DSNB610I csect-name MAXIMUM ALLOCATABLE BUFFER POOL STORAGE OF int1MB HAS BEEN REACHED. UNABLE TO CREATE/EXPAND BUFFER POOL bp-name TO SPECIFIED SIZE int2. BUFFER POOL IS NOW int3
Explanation
A buffer pool could not be created or expanded
to the requested size. The maximum amount of allowable buffer pool
storage, indicated by int1, has been reached.
The maximum allowable buffer pool storage is calculated to be twice
the amount of real storage that is available on the z/OS® image, or 1TB, whichever is less.
- bpname
- Indicates the name of the buffer pool that was affected.
- int2
- Indicates the size of the buffer pool that was requested.
- int3
- Indicates the actual size of the buffer pool that was created/expanded.
System action
The buffer pool is created or expanded to
the size allowed by the available storage within the maximum. If
the maximum has already been reached, then the buffer pool is allocated
at a minimum size as follows:
- 2,000 pages for 4K page size
- 1,000 pages for 8K page size
- 500 pages for 16K page size
- 250 pages for 32K page size
Once the maximum has been reached, buffer pool sizes are not allowed to be increased.
System programmer response
Analyze the buffer pool sizes and determine if any can be decreased, or consider adding more memory.
