In our organisation we are trying to connect our offhost application (built using CA GEN) through HIS server (installed on Windows Sever) which connects to further CICS regions in mainframes through VTAM.
We are trying to get the HIS connectivity replaced with CA Gen multi socket Listener software. This would mean that our application (installed on a desktop) would be directly connecting to mainframes through CA GEN multi socket listeners instead of routing through HIS Server.
Query is to check if there is any limitation on number of concurrent Users that could be parallel acquire connection and serviced by CA GEN multi Socket Listener. Are these dependent on some parameters which required to be configured?
I believe the TIML concurrent user limit is effectively the socket limit for Listener which is set by parameter NUMSOCK in the EZACONFG file (IBM z/OS V1R9 Communications Server: IP CICS Sockets Guide - United States)
That defaults to 50 and we normally recommend a value of 100 as a starting point (I understand the max is 999)
Additional Information I found:
Hope that helps
