The SDTRAN system
initialization parameter specifies the name of the shutdown transaction
to be started at the beginning of normal and immediate shutdown.
- SDTRAN={CESD|name_of_shutdown_tran|NO}
- The shutdown transaction enables CICS® to
shut down in a controlled manner, within a reasonable period of time.
For example, you can use it to purge and backout long-running tasks,
while ensuring that as many tasks as possible commit or back out cleanly.
For information about the CICS-supplied program, DFHCESD, started
by the default shutdown transaction, CESD, and how to use it as the
basis for your own transaction, see Shutdown assist program (DFHCESD).
Note: - The transaction runs under the userid authority of the issuer
of the shutdown command.
- If the program named by the shutdown transaction cannot be loaded, CICS waits indefinitely for all
user tasks to complete. This happens on an immediate, as well as
on a normal, shutdown.
- CESD
- Starts the CICS-supplied program DFHCESD.
- name_of_shutdown_transaction
- The 1- to 4-character name of your own shutdown transaction.
- NO
- Do not run a shutdown transaction. On a normal shutdown, CICS waits indefinitely for all
user tasks to complete.
