We are integrating two CICS applications. The interfacing mechanism is by means of CICS LINK from Application 1 to Application 2.
If application 2 is not responding to the request from Application 1 for a long time (about 5 seconds), then application 1
has to timeout and continue with its transaction processing. How this design can be achieved in CICS. Thank you!

EXEC CICS LINK has no mechanism for time outs -- so if you insist you have to use LINK, then what you want to do is not possible.

You could create a mechanism for time outs by using EXEC CICS START and using another transaction that is interval started to indicate when the time is expired. However, you would need to consult your site support group because problems with the transactions could cause you to start enough transactions to cause CICS to hit MAXTASK (causing problems for every application using that CICS region).
