Supported databases

A broker requires access to a database to store operational and state data. Databases from IBM and other suppliers are supported at specific versions on supported operating systems.

You must create the broker database before you create the broker, and specify the name of the database on the mqsicreatebroker command. The command creates tables to hold the broker data; these tables are listed in Database contents.

Start of changeYou can use the same database schema for all brokers that are at the same version, if appropriate, even if you create the brokers on different computers. The broker tables are created in a schema that is determined by the user ID that you specify for the broker database connection, and the rows within the tables are qualified by a unique identifier (UUID) for each broker. The schema user ID is set by -u dataSourceUserId (if you specified this parameter on the mqsicreatebroker or mqsichangebroker command), or by -i serviceUserId (if you did not specify the -u parameter).End of change

In most environments, the broker does not have to be running on the same operating system as the database server. For details about local and remote database use, and the restrictions that apply, see Database locations.

The following table, and the accompanying notes, indicate the minimum levels of products that are supported for databases on each operating system. For the latest information on all supported platforms, visit the WebSphere Event Broker Requirements Web site.

Notes:
  1. Supported releases of DB2, Oracle, and Sybase can participate as a resource manager in a distributed XA transaction, and can be coordinated by WebSphere MQ as the XA Transaction Manager. In WebSphere Event Broker, this support is referred to as globally-coordinated message flow support. On z/OS, all transactions are coordinated by Recoverable Resource Services (RRS).
  2. Start of changeAutomatic Client Reroute for DB2 is supported on all platforms except Solaris on SPARC and Windows.End of change
  3. Both the Oracle Database Server and the Oracle Runtime Client are required.
  4. Check the readme.html file for your product to check whether a fix pack or other fix is required.

    DB2 Version 8.2 is functionally equivalent to Version 8.1 Fix Pack 7. If you install DB2 Version 8.2 from the supplied CDs or DVD, you might see information that indicates the Version 8.1 level, for example when you use the command db2level.

  5. DB2 Version 9.1 requires WebSphere MQ Version 6.0.2.0 or later.
  6. You can use a remote SQL Server database on Windows from a Linux or UNIX® system using a supplied wire protocol driver.
  7. If you use DB2 Version 9.1 on HP-UX on PA-RISC, you must set the following environment variable, and export it in the broker's environment:
    MQSI_SIGNAL_EXCLUSIONS=10
  8. Start of changeThe Connect-Time Failover feature of Oracle RAC (Real Application Clusters) in a non-XA environment only is supported.End of change
  9. Start of changeIf you have installed Linux x86 (64-bit) Red Hat Enterprise Linux V4.0 or V5.0:
    • If you have installed DB2 Version 8 Fix Pack 9, you must use a 32-bit database instance. If you have a later release of DB2, you can use both 32-bit and 64-bit database instances.

      If you have installed Oracle, you must use the 32-bit client libraries.

    • XA is supported only if you use WebSphere MQ Version 6.0 (32-bit).

      If you do not require XA, you can install WebSphere MQ Version 6.0 (64-bit). XA is not supported because the 64-bit queue manager requires 64-bit ODBC drivers and switch files, which are not supplied.

    End of change
  10. If you have installed Linux zSeries® (64-bit) Red Hat Enterprise Linux V4.0, and you install a 31-bit DB2 Runtime Client, the client must be at DB2 Version 8 Fix Pack 10 or higher, and no other DB2 product can be installed on the same system. Therefore, the 64-bit DB2 server must be located on a separate Linux on System z image from the one in which the broker is installed.
  11. Solaris 10 on Solaris on SPARC requires DB2 Version 8 Fix Pack 9; Solaris 10 on Solaris on x86-64 requires DB2 Version 8 Fix Pack 11.
  12. You can use the embedded Derby database for verification, evaluation, and test purposes only. (Derby refers to the database product based on the Apache Derby open source project from the Apache Software Foundation.) For a production system, install and configure your chosen enterprise database.
  13. For XA coordination with Oracle 10g on Windows, you must install Patch Set 3 for Oracle 10g (10.1.0.4.0).
  14. On z/OS, DB2 is a mandatory requirement. You must create a unique database for each broker. See the Program Directory for WebSphere Event Broker for z/OS.
