Important! This parameter should only be used with the assistance of CA Support representatives. This parameter should not be used unless you have received the GV812 error message during an attempted restore.

XTNDOFF
►►─┬─────────────┬────────────────────────────────────────────────────────────►◄ └─ XTNDOFF=n ─┘
The XTNDOFF parameter applies only to data sets that were compressed by CA EXTEND/DASD for VSE. Thus, only data set exported by CA/FAVER for VSE or CA-FAVER2 for VSE would be candidates. The value of "n" overrides the offset to compression that was recorded in the CA EXTEND/DASD for VSE Control File. That value was extracted by CA-FAVER for VSE or CA-FAVER2 for VSE and stored in the exported data set's header record. In the rarest circumstances, this value might not have been updated when important structural changes to the compressed data set were made. In this event, the offset to compression stored in the header record must be overridden. The reload process validates the stored offset and automatically overrides it if is not at least the sum of key offset plus key length. If this occurs, a GV811 message is issued indicating the actual offset being used. The correct value is the offset, relative to zero, of the first data byte past all keys. That is, if this data set has an alternate index and the key area used by the alternate index is beyond the base cluster's key, then the XTNDOFF value would be the sum of the alternate index's key length plus its key offset.
