A broker requires access to a database to store operational and state data.
You must create the 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.
Multiple brokers
within a single instance can access the same database, if appropriate, because
the tables that are created are qualified by the broker name. Brokers in different
installation locations on the same system cannot share a database.
The
following table, and the accompanying notes, indicate the minimum levels of
database products that are supported on each operating system.
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.

Notes: - 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 aupport.
On z/OS, all transactions are coordinated by Recoverable Resource Services
(RRS).
If you use WebSphere MQ Version 6.0 as a transaction manager, all
datasources that are connected to DB2 from message flows in both 32-bit and
64-bit execution groups must connect to 64-bit DB2 instances.
- 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 FixPak 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.
- You can use a remote SQL Server database on Windows from
a Linux or UNIX system
using a supplied wire protocol driver.
On Linux (POWER platform), XA coordination is restricted to 32-bit
brokers only.
If you have installed Linux x86 (64-bit) Red Hat Enterprise Linux
AS V4.0:- DB2 is the only database supported on this operating system.
- If you have installed DB2 V8 FP9, 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.
- XA is not supported.

If you have installed Linux zSeries (64-bit) Red Hat Enterprise
Linux AS V4.0, and you install a 31-bit DB2 Runtime Client, the client must
be at DB2 V8 FP10 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 zSeries image from the one in which the broker is installed.
- Solaris 10 on Solaris (SPARC platform) requires
DB2 Version 8 FixPak 9; Solaris 10 on Solaris (x86-64 platform) requires
DB2 Version 8 FixPak 11.
- You can use the embedded Derby database for verification, evaluation,
and test purposes only. (Derby refers to IBM Cloudscape™ Version 10.0, a database
product that is built on the Derby database from the Apache Software Foundation.)
For a production system, install and configure your chosen enterprise database.
- On Windows, for XA coordination with Oracle 10G on Windows,
you must install Patch Set 3 for Oracle 10G (10.1.0.4.0).
- 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.
