Buffer Pool Statistics situations

You can monitor the system and determine when he number of locked buffer pool pages exceed the threshold.

IMS_BP_Locked_Count
Locked buffers will reduce the amount of storage available to the system, however they will also insure that the access to the data in the buffer is faster since the pages will be in memory. This is not a real problem unless your system has real storage constraints that are impacting other applications.

The formula is: Buffer_Pool_Statistics.Locked_Count GT 0
