IMS_Largest_Freeblock_Critical
The pool identified in this exception has exceeded the threshold for largest free storage area. When the largest area available becomes too small to handle the request, applications can stall or terminate. You can address this issue by reducing the amount of work being requested or increasing the amount of storage available in the pool.
The formula is:
Pool_Utilization.Largest_Free_Block LE
4096
IMS_Largest_Freeblock_Warning
The pool identified in this exception has exceeded the threshold for largest free storage area. When the largest area available becomes too small to handle the request, applications can stall or terminate. You can address this issue by reducing the amount of work being requested or increasing the amount of storage available in the pool.
The formula is:
Pool_Utilization.Largest_Free_Block LE
4916 AND Pool_Utilization.Largest_Free_Block GT 4096
IMS_PoolFreeBlocks
The pool identified in this exception has exceeded the threshold for number of pool fragments. This can lead to excessive amounts of paging or to applications stalling because they cannot get a large enough pool area to handle the request. You can attempt to reduce the fragmentation by terminating tasks that may not be critical to your environment.
The formula is:
Pool_Utilization.Free_Blocks GT 1
IMS_Pool_Util_High_Warning
The pool identified in this exception has exceeded the threshold for utilization. When pool space is exhausted, applications will stall while waiting for the pool space to become available again. You can address this issue by reducing the amount of work being requested or increasing the amount of storage available in the pool.
The formula is:
Pool_Utilization.Utilization_Percentage
GE 48.00 AND Pool_Utilization.Utilization_Percentage LT 60.00
IMS_Pool_Util_High_Critical
The pool identified in this exception has exceeded the threshold for utilization. When pool space is exhausted, applications will stall while waiting for the pool space to become available again. You can address this issue by reducing the amount of work being requested or increasing the amount of storage available in the pool.
The formula is:
Pool_Utilization.Utilization_Percentage
