Issue/Introduction

Planning to have a large number of concurrent users using the Gen CICS Multi Sockets Server Listener connection.
What is the best way to plan ahead and ensure that there are no impacts when the number of users is increased?

Resolution

The suggestion is to stress test by simulating the concurrent usage. 

From the Gen side of things, may need to adjust timeout values in EZACONFG and/or TIRSIPEX as needed. There could also be some CICS values that may need adjusting. For any questions on CICS values please check with CICS Administrator.

The adjustments for the Gen product would be:
In EZACONFG: 
ACCTIME ===> xxx Timeout Value for ACCEPT 
GIVTIME ===> xxx Timeout Value for GIVESOCKET 
REATIME ===> xxx Timeout Value for READ 

In TIRSIPEX: 
01 WORK-TIME-VALUE. 
03 WORK-SELECT-SECS-DEF PIC 9(8) BINARY VALUE 0.
03 WORK-SELECT-MICROSEC-DEF PIC 9(8) BINARY VALUE xxxxxx.
