Restarting and reopening areas after an IRLM failure

The internal resource lock manager (IRLM) ensures the integrity of databases in a data sharing environment.

To avoid compromising the integrity of the data in DEDB areas when an IRLM fails, all DEDB areas under the control of the failed IRLM are stopped. After you correct the failure and reconnect IRLM to the IMS system, you must restart and reopen the DEDB areas that the IRLM controls.

You can specify how IMS restarts and reopens DEDB areas after the IRLM reconnects, by using the FPRLM= keyword in the IMS and DBC procedures.
