Users may experience problems starting CCITCP/CCISSL or CCITCPGW/CCISSLGW. The job will attempt to initialize but terminate immediately after issuing messages similar to the following:
CAS9899I: Maximum # of Connection Threads = 199
ICH408I USER(user_id ) GROUP(STCUSERS) NAME(name)
INSUFFICIENT AUTHORITY TO THLMT
The message is due to CAICCI making use of the callable service BPX1STL to set the OMVS setting for MAXTHREADS to 2000.
Use the SETOMVS command to set the MAXTHREADS and MAXTHREADTASKS values to a minimum of 2001 and update your BPXPARM to reflect the change. Once this change is made, there is no need for CCI to make use of the failing callable service and the problem will be avoided.
You may also want to consult with your security team to determine why CCI is not authorized to make the change.
Console command to display current OMVS settings: D OMVS,O
Console command to set new value for MAXTHREADS: SETOMVS MAXTHREADS=2001
Console command to set new value for MAXTHREADTASKS: SETOMVS MAXTHREADTASKS=2001
