Creating Additional DB2 Database Queue Tables

If you decide to add an additional message queue to your system, you need to:

1.

manually create the database queue table needed to hold the new message queue.

2.

create the new message queue and map the database queue table to it (using the SWDIR\bin\swadm utility).

3.

add the message queue to the appropriate Mbox set (using the SWDIR\bin\swadm utility).

Each individual message queue must be held in its own database queue table.

Each database queue table must have the following characteristics:

•

the same column definitions as a sw_db_bgqueue_n, sw_db_wisqueue_n, or sw_db_predictqueue_n table. (Each of these tables has the same structure.)

•

no primary key.

•

the iProcess background user (default swpro) must have at least insert, select and delete permissions on the table.

•

the iProcess foreground user (default swuser) must have at least insert permissions on the table.

Warning

If a table that does not conform to these requirements is used as a message queue, messages cannot be enqueued to or dequeued from that queue, and the iProcess Engine may not function correctly.
