DFS4155W Maximum limit for active APPC conversations has been reached. New requests will be queued in 64 bit storage.
Explanation
The number of active APPC conversations in 31-bit storage reached the limit that is currently in effect.
System action
IMS queues any new APPC /IMS conversation requests in 64-bit storage until IMS can accept them for processing.
Operator response
No action is required.
Determine if either IMS is having a problem processing APPC/IMS transaction requests or if there is a sudden flood of incoming APPC/IMS transactions.
If both IMS processing performance and the number of incoming APPC/IMS requests are within acceptable ranges, consider increasing the APPC/IMS limits that are currently in effect. The APPC/IMS limits are specified on the APPCMAXC parameter in the DFSDCxxx member of the IMS PROCLIB data set.
