Region

Region name.

SYNC poin

ts

Number of successfully completed sync points during this interval.

DEDB call DEDB I/O MSDB call OBA high

Total number of DEDB calls during this interval. Total number of DEDB I/Os during this interval. Total number of MSDB calls during this interval.

Highest number of overflow buffers used during this interval.

NBA defn

Average number of normal buffers defined for this region during this interval.

This field is obtained from internal IMS control blocks, not from IMS log records.

UOW cont

Number of unit-of-work contentions during this interval.

DEDB buffer waits

Number of waits for a database buffer during this interval.

To limit the scope of the RFPR panel, add a sub-operand. An example is shown below.

DISPLAY RFPR (FPMSG3) Limits scope of display to the region named FPMSG3.
