A broker requires a database to contain operational and state data. Multiple brokers within a single instance can access the same database, if appropriate, because all tables are qualified by the broker name. Brokers in different installation locations on the same system cannot share a database. You can also configure message flows to access user databases.
The broker tables are created when you invoke the mqsicreatebroker command. The tables that are created are listed in Database contents.
The following table indicates which levels of database are supported on which operating systems. In most situations, the broker that accesses the database does not have to be running on the same operating system as the database server. For details about local and remote database use, and existing restrictions, see Database locations.

XA coordination for messages in the MRM domain on Windows requires DB2 Version 8.2 FixPak 10 or later.
If you use WebSphere MQ Version 6.0
as a transaction manager, all datasources connected to DB2 from message flows
in both 32-bit and 64-bit execution groups must connect to 64-bit DB2 instances.
If you deploy message flows that access databases, you can define
the message flows to be coordinated so that updates to those databases are
synchronized with updates to other resources.
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.
