Starting and stopping data sharing

Starting and stopping data-sharing operations involves starting and stopping the IRLM and database processing.

Starting the IRLM
Start the IRLM from the system console of each participating system with the START irlmproc,parms z/OS command.
Stopping the IRLM
You can terminate an IRLM normally only when all IMS systems that are using it have terminated. To stop an IRLM normally, use the STOP irlmproc z/OS command.
Starting and stopping database processing
In a data-sharing environment, IMS type-1 commands can act locally, that is, affect the local system only, or can act globally, that is, affect all sharing IMS systems in the sysplex.
