CICS Transaction Gateway V5 The WebSphere ... - IBM Redbooks

1. We started the CICS TG on z/OS as a started task from SDSF using the
command /S SCSCTG5. Having started the job, we noticed this caused several
temporary tasks to be invoked. These tasks were called SCSCTG5n, where n
was a number from 1 to 9. However, once the CICS TG had started the
original job SCSCTG5 was left running but paged out, and a child process
SCSCTG55 was left running and paged in. SCSCTG55 is the UNIX Systems
Services JVM process that is executing the Gateway daemon. This is shown
in Example 7-9.
To stop the CICS TG, we simply use the MVS cancel command against the
original started task: /C SCSCTG5. Eventually, the second task will end as well,
though you can cancel it too.

2. Once the CICS TG had started we checked the log file
/ctg/scsctg5/logs/ctg.stdout for the message CCL6524I, indicating the TCP
protocol handler had successfully started (Example 7-10).
