FPOPN= parameter for procedures

Use the FPOPN= parameter in procedure to specify whether to reopen DEDB areas automatically during IMS restart. Valid values are N, P, R, A, and D. The default is N.

N
Specifies that areas should not be reopened automatically during IMS restart. Areas that are registered with DBRC for preopening are preopened before the completion of an IMS start or restart as usual; other areas are not preopened.

This is the default.

P
Specifies that after an IMS normal or emergency restart, IMS should preopen those areas that are registered with DBRC to be preopened asynchronously and concurrently with normal IMS online processing.
R
Specifies that during IMS emergency restart, IMS should automatically reopen all areas that were open at the time of the previous IMS failure.

IMS reopens the areas after restart processing is complete. Reopening the areas occurs asynchronously and concurrently with normal IMS online processing.

During IMS normal restart, this option behaves the same as option P.

A
Specifies that during IMS emergency restart, IMS should automatically reopen all areas that were open at the time of the previous IMS failure. This option also specifies that IMS should preopen those areas that are registered with DBRC to be preopened.

IMS reopens the areas after completing restart processing. Reopening and preopening the areas occurs asynchronously and concurrently with normal IMS online processing.

During IMS normal restart, this option behaves the same as option P.

D
Specifies that during IMS control region initialization, the DEDB area preopen process is disabled. Areas that are defined to DBRC with the PREOPEN option are not opened. The open process occurs when the dependent region first requests data or when a /STA AREA command is issued after restart is complete. This option is valid for an IMS cold start, normal restart, and emergency restart. This option has no effect on an XRF tracking system or an FDBR system.

The FPOPN option does not change any area options in DBRC. This includes PREOPEN, VSO, and PRELOAD. These options remain set in the RECON data set.

This option does not affect DEDB forward recovery (REDO) processing. If an area requires forward recovery during an emergency restart, the area is opened, updated, and then closed.
