Locks

These locking metrics are reported for each monitored DB2 Data Sharing Group:

Deadlocks: Displays the total number of times that an application on a member subsystem could not obtain a lock from the internal resource lock manager (IRLM) because of a deadlock during the last polling interval.
Escalations: Displays the total number of times that member subsystems successfully performed lock escalations on a table space during the last polling interval.
Global Requests: Displays the global number of lock requests that member subsystems made for physical locks (P-locks) during the last polling interval.
Global Suspensions: Displays total number of suspensions on member subsystems because of an IRLM global resource contention (conflicting IRLM lock states) during the last polling interval.
Local Requests: Displays the total number of times that a member subsystem requested a lock from IRLM on behalf of the application during the last polling interval.
Local Suspensions: Displays the total number of times that an application on a member subsystem was delayed in obtaining a lock from IRLM during the last polling interval. The requested resource was being held by another task with an incompatible lock.
Timeouts: Displays the total number of times that an application on a member subsystem could not obtain a lock from IRLM after waiting for a site-specified period during the last polling interval.
