The utility SYSBPM is used for managing local and global buffer pools of
type Natural
, DL/I
or SORT
and message
pools.
In addition to functions for administration, SYSBPM also provides statistical information on the current status of a buffer pool of any type including the buffer pool cache (BP cache) and a message pool (if activated).Information is also provided on the Natural objects loaded in a buffer pool and the BP cache, and the messages loaded in a message pool.
For a general description of the Natural buffer pool (that is the buffer
pool of type Natural
) refer to
Natural Buffer Pool -
General, in 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
options are described in the Parameter Reference
documentation. The type of a buffer pool is determined by the
TYPE
subparameter of NTBPI
or BPI
.
Notes:
RUN
command will not be loaded into a buffer pool, only Natural objects executed
with the EXECUTE
command, that is the objects must
be stowed or cataloged.
The SYSBPM Utility - Buffer Pool Management documentation is organized in the following parts:
Note:
In this documentation, the buffer pool is also referred to as
"BP".
