The Client Option for CICS and Server Option for CICS versions 12.50.01 and 12.50.02 changed the SYGWCAAC, SYGWCAAS, SYGWCACC, and SYGWCACS user application stubs. These stubs are linked with the Client Option for CICS or Server Option for CICS user application programs. These application programs must be re-linked if any of the following situations apply:
EXEC CICS HANDLE CONDITION conditions are handled incorrectly in application programs.
Application programs are running under any version of z/OS after having been migrated from OS/390.
There is insufficient CICS storage (below 16Mb).
You do not need to re-link existing Client Option for
CICS or Server Option for CICS applications with the 15.0 version
if you have already re-linked with version 12.50.02.
