SYSBPM Utility - Buffer Pool Management

The utility SYSBPM is used for managing buffer pools of the type Natural, DL/I or SORT.

SYSBPM provides statistical information on the current status of the buffer pool including the buffer pool cache and on the Natural objects loaded in the buffer pool and the BP cache. SYSBPM also provides administration functions.

For a general description of the Natural buffer pool, refer to the Operations documentation.

The buffer pool is defined with the macro NTBPI in the Natural parameter module, or with the corresponding dynamic profile parameter BPI, both of which are described in the Parameter Reference documentation. The type of buffer pool can be determined with the TYPE subparameter of the NTBPI macro as described in Buffer Pool Initialization.
