ZPOOL GENERATION-Pool Generation and Reallocation Functions

Use this command to create new directory records or change existing directory records to conform to a changed file layout.

Requirements and Restrictions

Format




CREATE
creates initial pool directories or changes existing pool directories from FACE table (FCTB) generation input.

Notes:

  1. To preserve and merge existing pool directories into the newly created pool directories, enter ZPOOL GENERATION RECONFIGURE after you enter ZPOOL GENERATION CREATE. If you do not, all existing pool files are made available to the TPF system.

  2. Enter ZPOOL GENERATION UPDATE to make the newly created pool directories active.

RECONFIGURE
preserves and merges existing pool directories into the newly created pool directories.
Note:
You can specify this parameter only after you enter ZPOOL GENERATION CREATE.

UPDATE
rolls new pool directories into the pool rollin directory (#SONRI) and updates keypoint 9 (CTK9).
Note:
The current pool rollin directory (#SONRI) is first saved to the recoup SONRI save area (#SONSV) so it can later be used to restore the #SONRI if a problem requires you to do so.

FALLBACK
rolls the recoup SONRI save area (#SONSV) into the pool rollin directory (#SONRI) and updates CTK9.

ONLINE
specifies an action, where:

ABORT
forces ZPOOL GENERATION UPDATE or ZPOOL GENERATION FALLBACK processing to end without completing.

CONTINUE
continues ZPOOL GENERATION UPDATE or ZPOOL GENERATION FALLBACK processing.

INIT
creates the current pool segment table (#PSTXCUR).

Notes:

  1. Only specify this parameter when migrating to integrated online pool maintenance and recoup support. See TPF Migration Guide: Program Update Tapes for more information.

  2. Ensure that all pool segments in the FACE table (FCTB) are allocated. If you specify this parameter and there are pool segments in the FCTB that are not allocated, the #PSTXCUR and #PSTXNEW records that are built will not match the current pool configuration.

Additional Information

None.

Examples

The following example creates the information necessary for pool generation and reallocation.
