The fields in the RFPP panel are described below.

DBBF

DBFX

BSIZE

Total number of Fast Path database buffers defined. This is the DBBF parameter in the IMS startup procedure. Buffers defined for system use. This is the DBFX parameter in the IMS startup procedure. Size of each Fast Path buffer. This is the BSIZE parameter in the IMS startup procedure.

Avg number of regions waiting for free buffers

Average number of regions waiting for a free buffer during this interval.

Total DBBF

Total buffers in the Fast Path buffer pool.

Unfix Bufs New Region

Average number of Fast Path buffers defined that are not page fixed for use by regions or output thread use.

Unfix Bufs New Region is the number of non-fixed buffers that are available for normal buffer allocation (NBA) for additional (new) regions.

SDEPS

Average number of page fixed buffers that have a sequential dependent control interval (SDEP CI) defined.
