Steps for diagnosing CICS listener not initialized

Determine why the CICS® Listener did not initialize.

Perform the following steps:

1. Use the EZAC transaction to verify that the listener is defined in the configuration file.
2. In the configuration-file record for that listener, verify that IMMEDIATE is set to YES, and then verify that the correct APPLID and port number are specified.
3. Verify that the listener is properly defined in a CICS RDO group and that the RDO group is in the proper group list.
4. Check the message logs for failures.
   1. If there are no messages, start CICS with auxtrace active IP CICS Sockets CICS tracing enabled, and then request an SVC dump of CICS.
   2. If there are messages, call the Support Center.
5. If an EZY1292E message was issued, investigate why the CICS socket interface did not initialize. See Steps for diagnosing CICS socket interface not initialized.
6. If an EZY1369E message was issued, investigate why the TCP/IP stack as specified on the IP CICS Sockets interface TCPADDR configuration option did not initialize. See Steps for diagnosing problems for steps on diagnosing TCP/IP problems.
