Setting CICS options for threads

The CICS® attachment facility provides a multithread connection to Db2 to allow you to operate Db2 with CICS

About this task

. Threads allow each CICS application transaction or Db2 command to access Db2 resources.

Procedure

Use the CICS resource definition online (RDO) to tune the CICS attachment facility and define the characteristics of your threads.

When a transaction needs a thread, an existing thread can be reused or a new thread can be created. If no existing thread is available, and if the maximum number of threads has not been reached, a thread is created.
