You must define and initialize the IPROTECT format-2 global record before you use selective database recoup support.
About this task
The IPROTECT format-2 global record is a
control file that is used to track the processing and maintain statistics that are related to the
roll-in of a selective database recoup. The control file also
provides the capability to restart selective database recoup
processing when a system outage occurs.
Procedure
-
In each subsystem, enter the following command to define the IPROTECT format-2 global record:
ZGLBL GLOBAL DEFINE IPROTECT LOC-64BIT PROT-YES PROC-YES IS-NO KEY-YES SYNCH-NO
LOAD-DEM
-
In each subsystem, enter the following command to initialize the IPROTECT format-2 global record:
ZGLBL GLOBAL INITIALIZE IPROTECT SOURCE-ZERO SIZE-1000 PROC-ALL
-
On the processor that has the ownership of the POOL utility in the processor ownership table
(PROT), enter the ZRECP PROTECT command with the SETUP
parameter specified in each subsystem.
This parameter initializes the IPROTECT format-2 global record to the default settings for the selective database recoup.
-
If the z/TPF system uses the High Performance Option (HPO) feature and is running in a loosely coupled configuration, enter the following command to copy the
initialized IPROTECT format-2 global record to all
processors in the z/TPF complex:
ZGLBL GL INIT IPROTECT SO-GL FROMGL-IPROTECT FROMPROC-x
PROC-ALL
where x is the processor ID of the POOL utility owner.
