schema:text: If you are unsure of whether you require our Universal Data Access drivers, please review the questions posed below: Do you need to query a database with a 3rd party application? Is your application ODBC- or JDBC- compliant? Does your network environment support the TCP/IP or SPX protocol? OpenLink's Data Access Drivers provide ODBC and JDBC connectivity between compliant applications and databases. Moreover, OpenLink's drivers use the TCP/IP network protocol to achieve this connection. Consequently, if your response is YES to the aforementioned questions, you need these drivers. If you are still unsure, please consult your Database Administrators, System Administrators, or other knowledgeable staff. Users who respond NO to one or more questions must clarify their needs with either a Support Consultant or their Account Manager. We offer other solutions which might be what you require.

Query two or more heterogeneous databases simultaneously? -- Category 3. Migrate data from one DBMS to another? If you fall into Category 1, you require our UDA drivers. If you fall into Category 2, you require our Virtuoso suite. For category 3, we recommend the Virtuoso suite. Alternatively, if you are using an existing Data Migration tool such as Oracle HS services, UDA is what you require as these drivers work in conjunction with other data migration utilities such as Ms SQLServer's DTS Wizard. Does OpenLink provide Single-Tier or Multi-Tier drivers for the evaluator's DBMS? -- Category 1 - Yes. -- Category 2 - No. Evaluators in Category 1 may use the appropriate UDA driver for your database. If you fall into the second Category, you may use OpenLink's generic ODBC UDA drivers. Both the generic Single-Tier and Multi-Tier ODBC drivers connect to 3rd-party Data Sources, which allow connectivity to your DBMS. Does your evaluator have the database native client? -- Category 1 - Yes. It is installed on the same machine as the client application. -- Category 2 - Yes. It is installed on a different machine on the network. -- Category 3 - No. For evaluators who fall into the Category 1, we recommend Our OpenLink Single-Tier drivers. We recommend OpenLink's Multi-Tier drivers to evaluators in Category 2. Evaluators in Category 3 must install the OpenLink server components on their database server. NOTE:Evaluators in Category 2 may install the OpenLink server components on their database server or any machine, which contains the database native client. In this scenario, the OpenLink database agent can connect to the database through that database client. Please see the technical article on connecting via in a three-tier environment

schema:name: How can I prevent performance problems? -- Answer
schema:category: JDBC UDA ODBC
schema:text: As the OpenLink MT and ST drivers are middleware software, it is important to note that its performance can be influenced by the Client and Server configurations in use. This means, lack of system memory, kernel configurations, disk space, sql queries, coding techniques, un-indexed tables, network can all play a major part in the performance of the driver. Notwithstanding, we have outlined below ways in which you can increase the performance of the drivers. 1. Use OpenLink Single-Tier drivers where possible. 2. It is always recommended that, OpenLink's latest drivers are used where possible as these contain patches that might alleviate any performance bottlenecks you are facing. Only use OpenLink 4.2 drivers where we do not have a driver available. If you request this driver, please contact a Product Support consultant who will liaise with your Account Manager. 3. Establish 3-Tier Multi-Tier connections when Single-Tier connectivity is not possible. 4. Establish shared memory connections to databases that provide sockets and shared memory alternatives. 5. Check your DSN's "Defer fetching of long data" check box, when your result-sets contain binary data. 6. Locate the Row Buffer Size box that appears on your DSN setup dialog. Set this value to 1. Test. Next, set Row Buffer Size to 99. Test. Do you see a difference? If the first test is faster, your performance problems may stem from the makeup of your result-sets. If the second test is faster, your performance problems may stem from network latency. This awareness will help you set your Row Buffer Size in a manner that is beneficial to your situation. 7. Test a variety of client and server cursor modalities. Choose the modality that suits your application needs and provides the best performance. 8. If you are using the Multi-Tier Drivers, you can also increase the Send & Receive sizes. These might have an adverse effect on the network if you increase it sharply. Please consult your Product Support consultant if you want more information on this. If you increase this value, please ensure the Client (Send size) matches the Server (Receive size) and vice versa. Typically, this value is only increase when sending data from the Server to the client 9. If using the Multi-Tier drivers, please ensure your Reuse Rule is set in a manner that is appropriate for your system. If you anticipate long and complex queries, it is recommended that you do not reuse the agent. Alternatively, if you are in an environment that utilizes short, sharp bursts at the system, it might be conducive if you share agents, this means less system processes and resources will be instantiated on your system. 10. In OpenLink 5.x Multi-Tier, we have introduced the Linger Timeout. This creates a Connection Pooling environment on the server when handling connections. This means dormant connections can be reused.

Unix users must login to their Unix servers and cd into the root of their OpenLink installations. These users may run openlink.sh in a Bourne or Bash shell. Alternatively if you are using a C shell, you require openlink.csh. 2. All users must open their Session Rules Books. The Session Rules Book is the oplrqb.ini file, which reside in the /bin sub-directory of the OpenLink installation. Users may open oplrqb.ini with vi, Notepad, or another text editor. Locate the Environment section that corresponds to your OpenLink database agent and set the variables that are appropriate to to your Database setup. Typically, the main information required is the installation directory and location of the database libraries. If you are unsure what these values are, please request them from your Database or System administrator. Typically running the command `env' under the guise of the database owner will provide you with the necessary information 3. Users must start their OpenLink Request Broker services. To do this on Unix, from the shell or terminal prompt run ./oplrqb either from the /bin sub-directory of your OpenLink installation or if openlink.sh/csh has been run, anywhere in the system. Windows users may start oplrqb with their Services Control Panel utility.

The first part of the URL designates the machine (openlinux.openlinksw.com) on which it started. The number appended to the end of the machine is the TCP port on which it listens. This port is also the HTTPServer port that appears in the www_sv.ini file. The www_sv.ini file appears in the /bin/w3config sub-directory of OpenLink server components installations. The Admin Assistant will write simple error messages to the log when startup fails. Consultants must search the knowledge-base for the import of these errors. Finally, we have reviewed the default Admin Assistant log entries. However, users can cause the Admin Assistant to run at log level 7. This is achieved by setting the log level in the [www_sv] of the Session Rules Book. For example: [www_sv] Program = w3config/www_sv Directory = w3config CommandLine = +loglevel 6 Log level 7 causes the Admin Assistant to output an HTTP log that display individual scripts and images as it serves them.

schema:category: JDBC UDA ODBC
schema:text: Do you have an OpenLink 4.x or newer license? If so, take the following action: 1. Save the license to the directory that contains asnprint.exe. 2. Open a DOS prompt. 3. cd into the directory that contains asnprint.exe. 4. Run asnprint.exe . For example: asnprint.exe oplrqb asnprint.exe reveals the following, useful information: -- SerialNumber - Does the user report Duplicate Serial Number errors? If so, gather all licenses from the user environment and compare serial numbers. The serial numbers must not be identical. Identical serial numbers show that the user is attempting to break the licensing agreement by using one license on multiple machines. Direct such users to Account Management. -- RegisteredTo - This parameter has no support value. -- NumberOfUsers - This value represents the number of client machines that can connect simultaneously. It is useful in resolving "exceeded maximum number of licensed connections errors." If a user experiences this error, compare the NumberOfUsers parameter to the number of client machines that connect at one time. Traces,log files, or database monitoring tools may also be needed to ascertain the true number of clients that are connected at one time. -- NumberOfConnections - This value represents the number of database sessions that may be opened simultaneously. It is useful in resolving "exceeded maximum number of licensed connections errors." If a user experiences this error, compare the NumberOfConnections parameter to the number of open database sessions. Traces,log files, oplshut -s output, or database monitoring tools may also be needed to ascertain the true number of sessions that are open at one time. -- NumberOfCPUs - This value must match the number of CPUs installed in the user's machine. -- Clients - An ODBC designation will prevent users from using the JDBC Data Access Mechanism. An JDBC designation will prevent users from using the ODBC Data Access Mechanism. -- ExpireDate - Check this parameter, if the user reports license expiration errors. Compare with the current date. -- Platform - Check this parameter, if the user experiences errors that suggest the license is invalid for the operating system. Compare with a uname -a from the actual machine. -- Availability -- Release - Check this parameter, if the user reports invalid license or upgrade license errors. Compare with Multi-Tier Broker and/or agent strings or Single-Tier version information. Consultants may open OpenLink's 1.x and 3.x licenses to obtain the same information. Finally, if licensing problems persist, take the following action: -- Insure that only one license appears on the relevant machine. -- Insure that Multi-Tier Request Brokers are restarted or reinitialized. -- Insure that Single-Tier drivers and Single-Tier licenses share the same product code. As a last resort, reinstall and relicense the product. Wipe references to OpenLink products from Windows registries, where appropriate.

schema:text: Use the following guidelines to interpret Request Broker Log files. Tue Oct 15 2002 Make sure the log date corresponds to the occurrence of the problem. 12:25:46 using rule-book /home/openlink/32bit/v42/bin/oplrqb.ini Check the path to oplrqb.ini. Insure that the correct file is referenced. Users can encounter problems, when they have multiple, Multi-Tier installations. Specifically, users will notice that the wrong agents are spawned and the wrong environment variables may be employed. 12:25:46 bound UDP protocol to 0.0.0.0.60001 Check for UDP and "address in use" errors. Use netstat -a & the services file to debug any problems that occur with the UDP port. Likewise, insure that UDP is enabled on the client and server machines that produce UDP broadcast errors. 12:25:46 bound TCP protocol to 0.0.0.0.5000 Check for "address already in use" and other TCP port problems. Use netstat -a & the services file to debug any problems that may occur. In the event of a port conflict, users may change the Broker's Listen port. Users will find the Listen parameter in the [Protocol TCP] section of oplrqb.ini. 12:25:46 using UDP address 192.168.11.116.0 for IPC Check for UDP and "address in use" errors. Use netstat -a & the services file to debug any problems that occur with the UDP port. Likewise, insure that UDP is enabled on the client and server machines that produce UDP broadcast errors. 12:25:46 request broker started by openlink Brokers started by root may cause resource problems or Progress "login by batch" errors. Search for "batch" and resource related problems later in the file. 12:25:46 spawning /home/openlink/32bit/v42/bin/w3config/www_sv www_sv www_sv powers the Admin Assistant. Moreover, it uses the HttpPort passed in the www_sv.ini file. If "address" or other TCP port usage problems occur, run netstat -a and services to debug port conflicts. If necessary, have the user change the HttpPort in ~/openlink/bin/w3config/www_sv.ini file. 12:25:46 started persistent www_sv (pid=12219) 12:25:53 example.com called (*******) 12:25:53 request: domain=Progress 91C database=demo.db serveropts= 12:25:53 connectopts=-S pro91c -N tcp -H **** user= demo_user=unix readonly=0 These parameters are read from the Data Source Name. Check for inappropriate values. Additionally, watch for "Broker cannot resolve your request" errors. "Request" errors occur when the Domain name passed in this parameter list does not appear in the [Domain Aliases] section of oplrqb.ini. Users must create the appropriate in oplrqb.ini or choose an existing alias. 12:25:53 application=odbctest processid=12220 12:25:53 solve mapping: pro91c:demo:blank:other:example.com:odbctest:rw 12:25:53 using mapping: pro91c:*:*:*:*:*:* The Broker takes the abbreviated form of the domain alias and searches for matches in the [Mapping Rules] section of oplrqb.ini. The Broker will use the appropriate rule to prohibit or permit access to the database. Users may encounter "Mapping not found" errors, if their alias does not have an associated rule. Additionally, users may inadvertently create complex rules, which restrict their ability to connect. 12:25:53 using [generic_pro91c] ServerProgram=pro91c_sv Most mapping rules will point the Broker to a [generic] agent configuration section. This section passes the name of the database agent that is written in the database's CLI. It passes the location of database-specific environment variables, and it passes hard-coded connection parameters. Problems will occur on this line, if the agent configuration section does not exist in oplrqb.ini. 12:25:53 connect params: domain=Progress 91C db=demo.db serveropts=-T /tmp -d mdy -TB 31 -TM 31 -q -NL readonly=0 12:25:53 connectopts=-S pro91c -N tcp -H oplushp2 user= demo_user=unix machine=example.com application=odbctest This line shows the final list of parameters that will be used to establish the connection. In essence, the Broker tosses out specific Data Source Name parameters if corresponding parameters are hard-coded in oplrqb.ini. These hard-coded parameters can result in problems, if the user forgets they exist. Typically, users will discover that they are connected to the wrong database, they are authenticated as the wrong user, or they are restricted to read-only access. They may also experience authentication problems, which arise when OPSYSLOGIN is enabled. OPSYSLOGIN uses operating system parameters to authenticate. It does not recognize the typical database username and password. 12:25:53 spawning /home/openlink/32bit/v42/bin/pro91c_sv generic_pro91c This line shows the agent that is spawned for the connection. Problems occur if permissions prohibit spawning. Problems also occur when the agent is not compatible with the operating system or the agent cannot be found. 12:25:53 setting Environment PROGRESS91C 12:25:53 change environment 'CURSOR_SENSITIVITY' -> 'LOW' 12:25:53 change environment 'DLC' -> '/dbs2/progress/v91c' 12:25:53 change environment 'PROCFG' -> '/dbs2/progress/v91c/progress.cfg' The [generic] agent configuration section contains an Environment parameter. This parameter passes the location of an [Environment] section. This [Environment] section passes database-specific environment variables that are needed to establish the connection. Problems arise when the [Environment] section does not exist in oplrqb.ini. 12:25:53 asking agent for server handle "Server handle" errors occur when the preceding environment variables are incorrect. If environment variables are correct, consult the OPIE knowledge-base for additional information. 12:25:53 got it! 12:25:53 asking agent for connection handle "Connection handle" errors occur when connection parameters are incorrect.

schema:name: How Do I Interpret Request Broker Version Strings? -- Answer
schema:category: ODBC UDA JDBC
schema:text: Request Broker Version Strings produce the following information: Version Information - Is the Broker current? Is the Broker version associated with specific limitations, formal bugzillas, or other known problems? Platform of Compilation - Compare the platform of compilation information with the output of uname -a on the affected server. Is the Broker compatible with that operating system? Finally, version string errors provide useful, diagnostic information. Failure to produce version strings often stems from one of three problems: 1. The Broker does not exist on the system. 2. Permissions prohibit the execution of the Broker version string. 3. The Broker has file dependency issues. Users may need to adjust PATH or other environment variables to pick up needed libraries. Request Version Strings should be compared to Database Agent Version Strings and Client Version Strings to insure compatibility. Compatibility and stability problems arise, when Multi-Tier component versions differ.

schema:name: How Do Your Drivers Work? -- Answer
schema:category: ODBC UDA JDBC
schema:text: OpenLink's Single-Tier drivers are client-side drivers. Users install most Single-Tier drivers on a machine, which contains the database native client. The drivers connect to this native client and send queries-through the client--to the database. In essence, the database native client speaks a proprietary network protocol that bridges the gap between a local driver and a remote database. OpenLink's MS SQLServer, MySQL, PostgreSQL, and Sybase drivers are "wire protocol" drivers. These drivers contain libraries, which allow them to speak their database's native network protocol. Hence, users may install these drivers on any supported operating system. These drivers do not need the database native client to connect. OpenLink's Multi-Tier drivers are client/server drivers. All users install the client on the machine, which contains their client application. Most users install OpenLink's Multi-Tier server components on a machine that contains the database or the database native client. OpenLink's Multi-Tier server components consist of a Broker and a database-specific agent. The Broker responds to client requests and spawns the database agent that is designed to speak to the intended database. This agent is written in the database CLI and may speak directly to the database or proxy queries through the database native client. Moreover, the database agent is responsible for the return of data to the calling application. Finally, persons with MS SQLServer, MySQL, PostgreSQL, and/or Sybase databases may install their Multi-Tier server components on any supported operating system. These agents speak the database native communications protocol. Consequently, they can establish connections to remote databases without the aid of the database native client.

schema:text: The following guidelines enable you to establish the values that you need to pass in a client/server Data Source Name. Name Provide any descriptive title for your Data Source Name. Limit the name to 32 characters and start with an alphanumeric character. Description You may provide an optional description for your Data Source Name. Server This field passes the hostname or IP address of the machine that contains your OpenLink server components installation. It also passes the TCP port on which the Request Broker listens. If you do not know the hostname or IP address of the machine, you may run hostname on the console. If you do not have access to the console, contact its System Administrator. The Broker's TCP port is recorded in the Session Rules Book. The Session Rules Book is the oplrqb.ini file that appears in the /bin sub-directory of the OpenLink server components installation.

You may name your Data Source Name anything you want, so long as it observes length and special character considerations. However, you should consult your Database Administrator, if you need assistance with the database-specific connection parameters. The database-specific parameters are parameters that the various database native clients use to connect to the database. OpenLink Product Support Staff is familiar with many database native clients.

schema:name: I Suspect That My User Is Experiencing Port Or Networking Problems. What Do I Do? -- Answer
schema:category: ODBC UDA JDBC
schema:text: Port and networking problems arise in a variety of contexts. Choose the context that corresponds to your user: 1. Do firewall restrictions prevent a user from download OpenLink software? Test both HTTP and FTP links. Provide a DAV link to the file. Attempt to FTP the file to a user site. Attempt to email components to the user. Provide files to user via CD. (Requires Manager Approval.) 2. Do networking problems prevent transfer of an OpenLink download to the target machine? Urge the user to seek assistance from the on-site network administrator. Tell the user to transfer the file(s) via CD or disk. 3. Do port problems prevent Multi-tier users from starting their Request Brokers? Login to the machine that contains the Multi-tier server components. Use a text editor to open the oplrqb.ini file that resides in the /bin sub-directory of the OpenLink installation. Locate the [Protocol TCP] section. Locate the Listen parameter. (1.x and 3.x users locate PortLow.) Close oplrqb.ini. Run netstat -a. If Listen or PortLow is occupied, assign a new port in oplrqb.ini. If Listen or PortLow is not occupied, this may not be a port problem. 4. Do users not know what ports to pass in OpenLink data source names? Inform users that the only OpenLink-specific ports appear in the [Protocol TCP] section of the server component's ~/openlink/bin/oplrqb.ini file. Any other port would be gleaned from database-related configuration files or utilities. 5. Do firewalls prevent Multi-Tier clients from contacting Multi-Tier Request Brokers? Login to the machine that contains the Multi-Tier server components. Use a text editor to open the oplrqb.ini file that resides in the /bin sub-directory of the OpenLink installation. Locate the [Protocol TCP] section. For example: [Protocol TCP] PingWatchdog = No PingInterval = 600 ;IPAddress = 127.0.0.1 PortLow = 5000 PortHigh = 5020 Make sure PortHigh is uncommented and set. PortHigh should equal PortLow + the number of concurrent connections granted by the license + a few extra ports. Record the PortLow-PortHigh range. Record the Listen port value. (OpenLink 1.x and 3.x do not have Listen.) Close oplrqb.ini. Open the Listen and PortLow-PortHigh TCP ports on the firewall. Open UDP port #60001--in addition to TCP PortLow-PortHigh--to accommodate 1.x and 3.x drivers. 6. Do Multi-Tier port settings restrict the number of concurrent connections? Login to the machine that contains the Multi-Tier server components. Use a text editor to open the oplrqb.ini file that resides in the /bin sub-directory of the OpenLink installation. Locate the [Protocol TCP] section. For example: [Protocol TCP] PingWatchdog = No PingInterval = 600 ;IPAddress = 127.0.0.1 PortLow = 5000 PortHigh = 5020 Make sure PortHigh is uncommented and set. PortHigh should equal PortLow + the number of concurrent connections granted by the license + a few extra ports. Save changes and exit the file. Restart or reinitialize the Request Broker and test.

schema:name: What Do I Do If My Applications Fail To Connect After I Upgraded My 1x3x Drivers To 4x5x? -- Answer
schema:category: ODBC UDA JDBC
schema:text: OpenLink's 1.x and 3.x Multi-Tier drivers use different JDBC connection mechanisms. The older drivers route the request through a JDBC-specific agent that speaks to a database-specific agent. Here is the sequence of events needed to perform this task: 1. User creates a JDBC connection URL. For example: jdbc:openlink://localhost:5000/SVT=Ingres II/DATABASE=iidbdb/UID=ingres/PWD=ingres/JDBCAGENT=jodbc 2. The Broker associates all JDBC connection attempts with one of the JDBC Domains that appear in the [Domain] section of the Session Rules Book (oplrqb.ini). For example: [Domain Aliases] jodbc = jodbc judbc = judbc jdbc = jdbc 3. The Broker uses the Domain Alias to resolve the connection using one of the JDBC Mapping Rules from the [Mapping Rules] section of oplrqb.ini. For example: [Mapping Rules] jodbc:*:*:java:*:*:* = accept jodbc_client judbc:*:*:java:*:*:* = accept judbc_client jdbc:*:*:java:*:*:* = accept jdbc_client *:*:*:java:*:*:* = accept judbc_client 4. The Mapping Rules associate the connection attempt with a JDBC agent configuration section. For example: [jodbc_client] Program = jodbc_sv.exe CommandLine = ;+debug ReUse = never 5. The agent configuration section controls which JDBC agent is spawned to service the connection. In the above instance, jodbc_sv.exe is spawned. The JDBC agent spawns the database agent that corresponds to the SVT parameter of the JDBC connection URL. The following sections of the Rules Book shows how SVT=Ingres II causes the JDBC agent to spawn the oig2_sv database agent: Domain Aliases] Ingres II = oig2 [Mapping Rules] oig2:*:*:*:*:*:* = reject The Ingres II Database Agent is not configured [generic_oig2] Program = oig2_sv.exe Environment = INGRES_II OpsysLogin = Yes ReUse = never OpenLink's newest drivers omit the need for a distinct JDBC agent. JDBC-specific Domains, Mapping Rules, Agent Configuration Sections, and agents are omitted from the connection resolution. Instead, the Broker resolves the JDBC connection URL using only the SVT parameter. The database agent that is spawned is now able to handle both ODBC and JDBC connections Users may prevent most problems by removing JDBCAGENT= from their JDBC connection URLs. If problems persist, advanced users may resolve most problems by editing the Session Rules Book. New users are encouraged to contact OpenLink Product Support. Some 1.x and 3.x users create hybrid connections that pass an ODBC DSN in a Type 3 JDBC URL. For example: jdbc:openlink://localhost:5000/DSN=My Ingres Data Source/UID=ingres/PWD=ingres This connection format is no longer supported.

The actual Windows Single-Tier driver name begin with `ntl' (WinNT Lite) and end with a series of numbers and letters that denote the driver version and intended database. The actual Unix Single-Tier driver name begins with some combination of letters that represents the intended database, and it ends with _mt_lt (Multi-Threaded Lite) , _mt_lu (Multi-Threaded Lite Unicode), _st_lt (Single-Threaded Lite), _st_lu(Single-Threaded Lite Unicode). OpenLink's Unix-based iODBC Driver Manager is named libiodbc and ends with a .la, .sl, or .so extension. OpenLink's Multi-Tier Request Broker is named oplrqb. OpenLink's Multi-Tier Database Agents begin with a three or four character name that designate the intended database, and they end with a .sv (Single-Threaded version) or .mv (Multi-Threaded version) extension.

schema:name: What to do in case of Installation Failure? -- Answer
schema:category: ODBC UDA JDBC
schema:text: OpenLink's installers seldom fail. Furthermore, it is easy to troubleshoot installer issues, when they occur. Use the following guidelines to assist your users: 1.Obtain the name of the user's installation files. 2.Obtain the user's operating system and version. UNIX users should provide the output of uname -a. Linux users should provide the output of uname -a and rpm -qa | grep lib. 3.Insure that the installation files are compatible with the user's operating system. Most installers are compatible with the intended o/s and updated versions of the o/s. For instance, Solaris 2.7 software should run on Solaris 2.7 and 2.8. It may not run on 2.5. 4.Tell users to ftp installation shell scripts in ASCII. .taz, .dmg, and .zip files require BINARY transfer. If the problem persists, invite UNIX users to use tar -xvf file name to decompress their .taz files. Use of tar should create a functional installation. However, environment variables may remain to be set in the product configuration files: i.e., openlink.sh, openlink.csh, openlink.ini, oplrqb.ini. Ask Windows users to check their OpenLink installation directories and registry. Occasionally, Windows installers report registry problems. However, these same installers create functional installations with properly configured variables. Consequently, users should attempt to start their brokers and test their DSNs. Finally, some Windows users may need to make substantial edits to their registries after an installer failure. Address this course of action with expert users. Do not encourage novice users to pursue this task.

If on Unix, ensure that the Single-Tier license is placed in the b/in sub-directory of the OpenLink installation. Alternatively, users may pass the full path to licenses to OPL_LICENSE_DIR. This variable may be set using the command line, openlink.sh, openlink.csh, or your .profile. 3. Multi-Tier users ensure the licence is placed in the bin/ sub-directory of the server component installation. 4. Ensure that ftp transfers are conducted in binary. OpenLink's .lic licenses are binary-format files. 5. Windows Single-Tier users should uninstall their software, remove all references to Single-Tier software from the registry, and reinstall, if licensing problems persist. Occasionally, Windows Single-Tier users experience registry corruption, which necessitates the registry wipe and reinstall. OpenLink consultants have other utilities that may help debugging if you suspect a license-file is corrupt. The license version must match the Single-Tier driver version or the Multi-Tier request broker and agent version. Operating System Licenses must be generated for the appropriate operating system. CPU's The number of CPUs cited in the license must match the number of CPUs present in the machine. Access Mechanism Licenses may restrict ODBC or JDBC data access. Other licenses permit both ODBC and JDBC access. Database Licenses must list each of the databases to which the user intends to connect. Applications Certain licenses are limited for use with one application. OpenLink's 1.x and 3.x ship with a license text file. Consultants may open this license with Notepad or a similar text editor.

schema:name: What Does Disable RowsetSizeLimit Do? -- Answer
schema:category: ODBC UDA JDBC
schema:text: The OpenLink Scrollable Cursor Library (SCR) by default enforces a maximum cursor row-set size of 100 on any query. This is because the larger the row-set size the more memory the SCR will require to manage this, which could begin to unnecessarily impede performance as the system resources run low. Hence the need for this restriction as general no one should ever have the need to manipulate more data than can be viewed on their screen (ie a row-set). Thus if the an application makes SQLStmtOption(SQL_ROWSET_SIZE, value) where the value is greater than 100 our driver will return SQL_SUCCESS_WITH_INFO at which point a well written application which check SQLError and receive an "Option value changed" message at which point it should call SQLGetStmtOption(SQL_ROWSET_SIZE, &value) to see what it has actually been set to, which would be 100. Some applications, for example Power Builder, ignored the SQL_SUCCESS_WITH_INFO response and assumed the value they requested resulting in errors when they attempted to scroll paste the end of the row-set (100 rows) our driver returned. To enable such applications to work with our driver we thus introduced the Disable Rowset Size Limit option which if set removes our imposed restriction and trusts the application to set the row-set size to a reasonable value.

schema:name: What Does Dynamic Cursor Sensitivity Do? -- Answer
schema:category: ODBC UDA JDBC
schema:text: Enables or disables the row version cache used with dynamic cursors. When dynamic cursor sensitivity is set to High, the Cursor Library calculates checksums for each row in the current row-set and compares these with the checksums (if any) already stored in the row version cache for the same rows when fetched previously. If the checksums differ for a row, the row has been updated since it was last fetched and the row status flag is set to SQL_ROW_UPDATED. The row version cache is then updated with the latest checksums for the row-set. When dynamic cursor sensitivity is set to Low, (default) performance is improved. The calculation and comparison of checksums for each row fetched carries an overhead. as the application does not need to detect the row status, SQL_ROW_UPDATED.

For instance, select 10 + 12 in Progress will return the result as a numeric expression. In Progress SQL89/4GL, the Precision and Scale are returned as 0 as default. This means Applications, for example MSAccess, might interpret the results as a string and label it a char column. With these variables, the user has complete control over the Precision and Scale used for expressions. By default, the OpenLink drivers will return a default of 15,2 for Precision and scale respectively.

schema:name: What Does Field Size Maximum Do? -- Answer
schema:category: ODBC UDA JDBC
schema:text: This option is similar to the Expression Precision/Scale option. The Progress 4GL database engine allows the storage of character strings which are longer than the declared SQL width. For instance, creating a table with a char column will default to 8 but Progress will allow you to specify more than 8 characters. By specifying a Max value, with this option, the ODBC driver internally will override the value provided by the ODBC call SQLDescribecol and use the value provided.

schema:name: What Does Field Size Minimum Do? -- Answer
schema:category: ODBC UDA JDBC
schema:text: This option is similar to the Expression Precision/Scale option and is related to Field Size Maximum. As the Progress 4GL database engine allows the storage of character strings which are longer than the declared SQL width. For instance, creating a table with a char column will default to 8 but Progress will allow you to specify more than 8 characters. When the values are returned without this option, only the first 8 characters will be returned. By specifying a Min value, the ODBC driver will override the value provided by the ODBC call SQLDescribecol and will use the value provided instead. This is the more important of the two Field Size options and should always be specified first. For example, if your column as defined as char(8) but you have at least 255 characters, please specify a Min Field size of 255.

schema:category: ODBC UDA JDBC
schema:text: OCIPrefetchMemory and OCIPrefetchRows control parameters relating to the Oracle OCI's prefetching facility. However, use of this facility has been disabled in the OpenLink agent and Lite driver because of problems experienced with Oracle 8.x and indicator variables. To minimize server round trips and maximize performance, the OCI can prefetch result set rows when executing a query. This prefetching operates independently of OpenLink's prefetching facility. The OCI prefetching can be customized by setting two attributes, OCI_ATTR_PREFETCH_ROWS and OCI_ATTR_PREFETCH_MEMORY. The OCIPrefetchMemory and OCIPrefetchRows settings in the OpenLink setup dialogs map directly to these OCI attributes. OCIPrefetchMemory sets the memory allocated for rows to be prefetched. The application then fetches as many rows as will fit into that much memory. OCIPrefetchRows sets the number of rows to be prefetched. When both of these attributes are set, the OCI prefetches rows up to the OCIPrefetchRows limit, or until the OCIPrefetchMemory limit is reached, if this is lower.

When set to Full (-O 2), stored procedures are created for every call to SQLPrepare. This setting can result in decreased performance when processing statements that do not contain parameters. When set to Partial (-O 1) (the initial default), the driver creates stored procedures only if the statement contains parameters. Otherwise, the statement is cached and run directly at the time of SQLExecute. When set to None (-O 0), stored procedures are never created. The driver caches the statement, executes it directly at the time of SQLExecute, and reports any syntax or similar errors at the time of SQLExecute.

schema:name: Why Should I Upgrade? -- Answer
schema:category: ODBC UDA JDBC
schema:text: End-users are encouraged to upgrade to the latest software version. The latest software contains desirable new features and fixes for bugs. Additionally, support options are limited, when legacy software is involved. Development does not back-patch legacy bugs, and Support staff may have difficulties recreating legacy problems. The following table lists new features for recent software builds: 4.x ODBC 3.5 compliance. Multi-Threaded client & server components. Substantially-revised communications layer. 5.x Unicode support. Zero Config. Best communications layer.

schema:name: Answer to question: What is ODBC?
schema:category: ODBC UDA JDBC
schema:text: ODBC is short for Open Database Connectivity, an Application Programming Interface and Runtime Middleware that loosely-couples Applications and backend Database Management Systems (DBMS). ODBC was originally created by Microsoft as a Windows-specific API and Runtime component. Over the years it has been successfully ported and deployed across macOS, Linux, and a variety of Unix platforms via projects such as iODBC and unixODBC.

wdrs:describedby: n473:seo
schema:text: Configuration A: 4 cluster nodes, 3 instances per cluster node (quorum), 1 instance per host cluster node, 12 host cluster nodes. Configuration B: 4 cluster nodes, 3 instances per cluster node (quorum), 4 instances per host cluster node, 3 host cluster nodes. Performance has more to do with the number of Virtuoso Server processes running on each cluster node. One instance per cluster node will work better than four instances per cluster node. You will have more OS resources available as the Virtuoso instances are reduced. Ideally, you want to spread the instances over distinct machines so that you have resources pooled across those machines.

wdrs:describedby: n473:seo
schema:text: Virtuoso has supported Federated SPARQL a/k/a SPARQL-FED since the specification was created. Clustering has more to do with horizontal partitioning of the database across many machines (physical or virtual) to parallelize execution of queries, etc. SPARQL-FED may be used with a Virtuoso Cluster, just as with a Single-Server Instance.

Subject Item: n47:HighAvailAndRecoverAnswer
wdrs:describedby: n473:seo
schema:text: You can use replication for HA across Elastic Clusters or Single-Server instances. For example, nearly-instantaneous Transactional Replication is used by some of our larger customers (e.g., Globo of Brazil used a Transactional Replication setup for the entire World Cup 2014 without any issues).

Subject Item: n47:PlansCloudAnswer
wdrs:describedby: n473:seo
schema:text: Virtuoso Open Source Edition (VOS) is part of the LOD2 OpenStack deliverables, but this does not include Enterprise Edition features (i.e., no replication clustering, elastic clustering, fine-grained ABAC security, nor virtual DBMS functionality for making RDF views over external SQL data sources). That said, Virtuoso (both Open Source and Enterprise) may be instatiated on cloud services, including Amazon EC2.

schema:text: Yes. You start with Single-Server, enable the Elastic Cluster optionand then add nodes as scalability demands increase.

Subject Item: n47:VirtR2RMLAnswer
wdrs:describedby: n473:seo
schema:text: R2RML, a W3C Recommendation, is a language for expressing customized mappings from relational databases to RDF data sets. Such mappings provide the ability to view existing relational data in the RDF data model, expressed in a structure and target vocabulary of the mapping author's choice. R2RML mappings are themselves RDF graphs written in Turtle syntax. R2RML is becoming the generic standard adopted by most vendors of tools mapping relational data to RDF, enabling the interoperability of R2RML scripts, whether created with such tools or by hand. This page discusses how to use R2RML specifically with Virtuoso.
