Restart after IMS failure

Restart an IMS system in a data-sharing environment in the same way as in a nonsharing environment.

• Restart IMS normally, using the /NRESTART command, if you were able to shut the IMS system down normally.
• Emergency restart IMS, using the /ERESTART command, if the IMS system failed.

In a data-sharing environment, however, consider that if the associated IRLM also stops or fails, you must restart that IRLM before you start IMS in a block-level data-sharing environment. See Starting the IRLM.
