VERIFY input

VERIFY function syntax

    VERIFY( TYPE(LIST | ALLOC | OPEN)
            TIME(timestamp)
            RCVTYPE(TSR | PITR)
            SOURCE(PRI | SEC)
          )

Parameter reference

The VERIFY parameters are described in the following list:

TYPE(LIST |ALLOC | OPEN)

Use the TYPE parameter to specify the verification level that VERIFY will perform.

TYPE(LIST) provides a list of all log, image copy, and change accumulation data sets that are required for recovery. The list contains information that is extracted from DBRC about each data set.

TYPE(ALLOC) provides the same detail as TYPE(LIST), but TYPE(ALLOC) also allocates each data set with a deferred mount for tape data sets to verify the existence and physical accessibility of each data set.

TYPE(OPEN) provides the same detail as TYPE(LIST) and TYPE(ALLOC) but TYPE(OPEN) also opens each data set to verify its availability and usability.

The default is TYPE(LIST).

TIME(timestamp)

The TIME parameter provides a way to obtain information about recovery assets for a timestamp recovery, including recoveries to any prior point in time. TIME specifies the timestamp value that determines how much log and change accumulation data would be processed during recovery. Only log data sets that contain data from before the recovery timestamp will be reported. Only change accumulation data sets from before an allocation boundary, as defined by DBRC, will be reported. TIME() is an optional parameter. If TIME() is not specified, the VERIFY function will process recovery assets for performing a full recovery.

You must supply the timestamp value within an interval where the databases and fast path areas in the input list are unallocated if you specified RCVTYPE(TSR). The timestamp value can be any earlier point-in-time if RCVTYPE(PITR) is specified.

The format of the timestamp specification can be found in TIME and RANGE parameter processing.

RCVTYPE(TSR | PITR)

Use the RCVTYPE parameter to specify the type of recovery that is being requested.

RCVTYPE is an optional parameter.

TSR is the default parameter if TIME() is specified. TSR specifies that recovery assets verification for a timestamp recovery is to be performed. The timestamp must be such that no ALLOC records in the RECON span the timestamp that is supplied with TIME(). All RECON ALLOC records that have an ALLOC time that earlier than the recovery time must have one of the following specifications:

DEALLOC time:

The DEALLOC time must be earlier than the recovery time.

STOP time:

The associated PRILOG record must have a STOP time that is earlier than the recovery time. The associated PRILOG record is the one with a START time equal to the START time of the PRILOG START time specified in the ALLOC record.

Use the PITR parameter to specify that recovery assets verification for a timestamp recovery to any prior point in time (Point-In-Time Recovery) is to be performed. At the timestamp that is specified, database data sets and areas can be in any allocation state as recorded in the RECON data sets. Log data sets that span allocation intervals for the database data sets and FastPath areas in the input list, up to and including the specified recovery time, are reported. If PITR is specified, the timestamp that is supplied can be any value before the current time, but after the run time of a valid image copy that is registered with DBRC.

SOURCE(PRI | SEC)

Use the SOURCE parameter to specify the source of image copies and log data sets for the recovery process.

If SOURCE(PRI) is specified, primary image copy and log data sets are used as the source for the verify process except for any that are marked as invalid in the RECON data sets. The status, as recorded in the RECON data sets, of the primary image copy and log data sets is reported.

If SOURCE(SEC) is specified, secondary image copy and log data sets are verified as the source for the recovery process. The status, as recorded in the RECON data sets, of the secondary image copy and log data sets is reported. The default is SOURCE(PRI).
