The utility SYSBPM is used for managing local and global buffer pools of type
Natural
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".
Instead of Message Buffer Pool, the abbreviation Message Pool is often used both in the user interface and in the documentation.
