REDEFINE for REBUILD INDEX

Use the REDEFINE option to avoid the normal deletion and reallocation of the index space data sets for STOGROUP-defined index spaces. This option is ignored for VCAT-defined index space data sets.

The value that you specify for the REDEFINE option applies to all STOGROUP-defined index spaces included in a single REBUILD INDEX command statement. To rebuild multiple STOGROUP-defined index spaces with some reallocated and others not reallocated, you must use one REBUILD INDEX command statement for the index spaces to be reallocated and a second REBUILD INDEX command statement for those index spaces not to be reallocated.

Regardless of the value of REDEFINE, if the data sets for a STOGROUP-defined index space do not exist, BMC AMI Recover creates the data sets.

Important

When you are rebuilding a multi-data-set, nonpartitioned index space, more or fewer data sets may result than were previously used.


Option

Description

REDEFINE YES

REDEFINE YES is the default. If you specify REDEFINE YES, BMC AMI Recover deletes and reallocates the VSAM data sets for STOGROUP-defined index spaces prior to the start of the BUILD phase. For more information, see Storage-group-defined-data-sets.

NOSCRATCH

If you specify NOSCRATCH with REDEFINE YES, BMC AMI Recover issues IDCAMS to uncatalog without scratching. You can use NOSCRATCH to support disaster recovery scenarios where the following items are true:

  • DASD volumes at the recovery site differ from those at the primary site.
  • The operating system catalog and the Db2 catalog and directory are restored before running BMC AMI Recover.
  • DB2 STOGROUPS are changed to point to the recovery site packs.

Using this option eliminates mount messages for the primary site packs that do not exist at the recovery site.

Important

REDEFINE YES has no effect if you specify INDEP OUTSPACE. For the instructions for creating data sets for INDEP OUTSPACE, see INDEP-OUTSPACE.

REDEFINE NO

REDEFINE NO tells BMC AMI Recover not to delete and reallocate the VSAM data sets for the index space. Use this option to treat STOGROUP-defined index spaces as VCAT-defined index spaces and to reallocate the VSAM data sets manually. New volumes are used as needed from the STOGROUP, even with REDEFINE NO specified.
