DSNB542I csect-name THE TOTAL ACTIVE PGFIX YES BUFFER POOL STORAGE EXCEEDS THE DB2 ALLOWED REAL STORAGE CAPACITY WHEN EXPANDING STORAGE FOR BUFFER POOL bpname CURRENT VPSIZE = cbpsize NEW VPSIZE = nbpsize REAL STORAGE CAPACITY = rsc MB.
Explanation
When expanding the VPSIZE for an active PGFIX YES buffer pool, Db2 detects that the total storage allocated for all active PGFIX YES buffer pools will exceed 80% of the real storage capacity on this z/OS® image. The ALTER BUFFERPOOL command fails and the buffer pool will continue to be active with the current VPSIZE value.
The buffer pool attributes and real storage capacity
are:
- bpname
- The buffer pool name.
- cbpsize
- The current VPSIZE for the buffer pool.
- nbpsize
- The new VPSIZE that was specified on the ALTER BUFFERPOOL command.
- rsc
- The real storage capacity of this z/OS image in units of megabytes (1 MB = 2**20 bytes).
System action
The ALTER BUFFERPOOL command fails. The buffer pool continues to be active with the current VPSIZE.
System programmer response
Either allocate more real storage to this z/OS image, reduce the requested size of the buffer pool or use the PGFIX NO attribute.
