Using the Database Utilities

>CONTROL

log ﬁle as separate transactions. If all of the databases involved in the

multiple database transaction are not speciﬁed in the >RECOVER or

>ROLLBACK command, DBRECOV will abort. It does not allow partial

recovery of multiple data base transactions. If a multiple database

transaction is dependent on any transaction that was not recovered, the

multiple database transaction will be rolled out.

NOMDBX causes DBRECOV to treat multiple database transactions contained in the

log ﬁle as single transactions. Therefore, each database can be recovered

separately. This option is useful if only part of a multiple database

transaction is to be recovered.

Record Numbers

DBRECOV identiﬁes detail records by their record number. Suppressing aborted or unended

transactions during recovery with the NOUNEND or NOABORTS options can cause

subsequent detail calls to DBPUT to use different record numbers. In order to change old

record numbers into new ones, DBRECOV uses an internal record table. The record table

provides a "before" and "after" location of the record numbers for DBPUT calls.
