Work file recover options

The following options enable you to specify values for the work files required during recovery.

Description

WORKFILE_MAX_PRIMARY

Limits the amount of primary allocation space to be used for the sort work space. It also applies to copies made to DASD. Valid values are 0 - 9999. Zero (0) indicates no limit.

BMC AMI Recovery Manager compares the maximum primary allocation to the value of the calculated primary allocation value and selects the smaller of the two. If the maximum primary value is selected, the primary space allocation is set to that value, the secondary space allocation is set to 1/15 of that value, and the value set for percent prime (if any) is ignored.

BMC AMI Recovery Manager calculates the number of units based on the maximum primary value. The unit parameter is UNIT=( workUnit, n) where n is the calculated number of units up to a maximum of 59.

Important

You must ensure that you use a maximum primary value that fits on your DASD devices. If the maximum primary value exceeds the capacity of a volume, the job will fail.

The capacity of typical DASD devices

The following gives examples of the capacity of some typical DASD devices:

Physical Data for 3380 (per device)		Physical Data for 3390 (per device)		Physical Data for 9345 (per device)
Single Density (Models D & J)	tracks: 13,275 cyls: 885	Model 1 (Single)	tracks: 16,695 cyls: 1,113	Model 1	tracks: 21,600 cyls: 1,440
Double Density (Model E)	tracks: 26,550 cyls: 1,770	Model 2 (Double)	tracks: 33,390 cyls: 2,226	Model 2	tracks: 32,340 cyls: 2,156
Triple Density (Model K)	tracks: 39,825 cyls: 2,655	Model 3 (Triple)	tracks: 50,085 cyls: 3,339	Not applicable	Not applicable
Not applicable	Not applicable	Model 9 (Mod 9)	tracks: 150,255 cyls: 10,017	Not applicable	Not applicable

WORKFILE_ALLOCATION_TYPE

Specifies whether the work file allocation quantities are expressed in cylinders (CYL) or tracks (TRACK) for the work files.

WORKFILE_WORK_UNIT

Use this option to specify a disk file for use when dynamically allocating work files.

Tip

To determine the size of the work file, run DSN1LOGP with SUMMARY(ONLY) and allocate the output to a disk file.

WORKFILE_PRIMARY_ALLOC

Use this option to specify the primary allocation quantity for work files. The default is 10, 20. This value is used when BMC AMI Recovery Manager is unable to estimate the quantity due to problems or when the DATASET_SIZING option is set to DEFAULTS.

WORKFILE_SECONDARY_ALLOC

Use this option to specify the secondary allocation quantity for work files. The default is 10, 20. This value is used when BMC AMI Recovery Manager is unable to estimate the quantity due to problems or when the DATASET_SIZING option is set to DEFAULTS.

WORKFILE_WORKDDN

Use this option to direct the sorting of extracted index keys in index recoveries.

Value	Description
NO	(Default) Sorts the keys without writing them to SYSUT1 and omits that file from the recovery JCL.
YES	Writes extracted index keys to a work file (SYSUT1) before sorting.

BMC AMI Recovery Manager ignores this option if you specify a value greater than 1 for MAXKSORT.

WORKFILE_WORKPREFIX

Use this option to specify the high-level name to use when allocating sort and work files.

If you specify a work prefix in the object set options, BMC AMI Recovery Manager uses that work prefix.
If you do not specify work prefix in the object set options, BMC AMI Recovery Manager uses the value of Work File Prefix in ARM$OPTS (see Product-options).
If Work File Prefix has no value in ARM$OPTS, BMC AMI Recovery Manager uses the user ID.
