DSNB536I   csect-name THE TOTAL VIRTUAL BUFFER POOL STORAGE EXCEEDS THE REAL STORAGE CAPACITY

Explanation

This message is issued as a warning that the total amount of allocated virtual buffer pool storage for this DB2® subsystem has exceeded the real storage capacity of the z/OS® image. The amount of real storage should be at least as much as the total amount of virtual buffer pool storage, and should also be enough to accommodate the EDM pool and DB2 working storage in addition to the virtual buffer pool storage. Paging activity in the buffers is an indication of a performance problem.

System action

Processing continues.

System programmer response

Allocate more real storage to the z/OS image. If there is not enough real storage to hold the buffers, then the number of buffers needs to be reduced. This might mean fewer concurrent users. If the number of buffers is reduced, then DB2 will issue the DSNB538I message when the total amount of virtual buffer pool storage no longer exceeds the real storage capacity.
