You would like to identify the CICS region that is the point of origin for a set of tasks that run in a number of CICS systems communicating with IP interconnectivity (IPIC). For example, you might be investigating ways to enhance your tracking of the path taken through a number CICS regions by a set of tasks that can be initiated by a user.
Your CICS Transaction Server for z/OS (CICS TS) region receives the messages DFHLD0555I and DFHLD0556I in the CSLB transient data queue. You would like to understand when these audit log messages will display.
This Technote gives guidance with using sample REXX exec DFH$RING to set up key rings on RACF subsystems which are each on a different sysplex. It addresses problems such as being unable to acquire an IPCONN when attempting to use client authentication and IPIC communication for the first time. It shows how to use the RACF export facility for certain certificates to export from the sysplex of the client CICS system to the sysplex of the server CICS system.
