REDEFINE for RECOVER BUILDINDEX
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 REDEFINE applies to all STOGROUP-defined index spaces included in a single RECOVER BUILDINDEX command statement. To rebuild multiple STOGROUP-defined index spaces with some reallocated and others not reallocated, you must use one RECOVER BUILDINDEX command statement for the index spaces to be reallocated and a second RECOVER BUILDINDEX command statement (in a separate execution of BMC AMI Recover) 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 allocates the VSAM data sets for the index space.
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:
Using this option eliminates mount messages for the primary site packs that do not exist at the recovery site. |
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. |
