Additional updates to CICS CSD definitions

If you plan to run multiple, concurrently executing IBM® Transformation Extender for Application Programming for the CICS runtime environment tasks that share the map keyed-sequential data sets (KSDS), set the CSDSTRNO parameter for the map KSDS equal to the maximum number of concurrently executing tasks you want to allow in the z/OS CICS region.

If you are adding the IBM Transformation Extender for Application Programming to an existing IBM Transformation Extender for Application Programming installation (meaning, that this is not a new installation), you must update the CSD. Unless you are planning on running multiple versions of IBM Transformation Extender for Application Programming in a single CICS region, remove the ASCLDSTX group from the CSD and add the new system definitions.

The use of CICS Temporary Storage Queues might increase if you upgrade from Mercator Integration Broker or Ascential Datastage TX. The VSAM-based work space manager has been replaced with a TSQ-based work space manager.

The benefits of using a TSQ-based work space manager is that it simplifies the installation process and improves the performance of your map execution. The storage requirements for TSQ might be impacted. You must ensure that there is enough available TSQ.
