IMS Connect security and the OTMARTUX user exit

The OTMA Resume TPIPE Security user exit (OTMARTUX) is not an IMS Connect exit routine, but it is one of two possible methods that you can use to secure messages queued on the OTMA asynchronous hold queue. The other method is to use an external security product, such as RACF®. You can use the OTMARTUX user exit and an external security product each by itself or in combination.

The OTMARTUX user exit runs in the IMS control region and not in the IMS Connect address space.
