Setting up access to CICS for Data Replication for VSAM
The target CICS® region uses a z/OS® IP CICS socket (or CICS listener) to communicate with the apply service in the target server.
About this task
In the Data Replication for VSAM environment, there is one CICS target region per target server, with a CICS listener started.
- A connection to the CICS replication utility
- A connection to each instance of a CICS replication writer that is started
If you are setting up multiple replication environments, you must set up one z/OS IP CICS socket per target CICS region.
To ensure that your CICS listener is active, you can
issue the following TSO command on the apply server: DISPLAY
TCPIP,procname,NETSTAT,CONN
. You can also
issue this command from the system console on the target server to
display the listeners.
For information about setting up a CICS listener, see the section about setting up and configuring CICS TCP/IP in the z/OS Communications Server: IP CICS Sockets Guide.
