Dan, The following response from Paul Kettley :-
You can set IDFORE and IDBACK to be high but realistically you wouldn't expect to hit those limits. These values relate to batch jobs , RRS batch jobs and TSO connections. Would you expect to have 1,000s of connected batch/RRS batch jobs at anyone time or would you expect to have 1,000s of TSO foreground users (even allowing for split screen). Probably not ! Maybe the important point is that IDFORE + IDBACK does not have to equal to CTHREAD. For example remember that each CICS regions will use 9 connections to the Queue Manager and the channel initiator will use the number of connections specified in ADAPS parameter of CSQ6CHIP (default =20). The CICS and CHINIT connections contribute to CTHREADS but have no link to IDFORE or IDBACK . I know this doesn't give you a specific answer but I hope it helps. cheers, Paul K Morag Hughson WebSphere MQ for z/OS Development Internet: [EMAIL PROTECTED] > It was recommended at the share conference to set CTHREAD to the max of > 32767.
