Oracle Rman Recover Archive Files
Oracle Restore Database Rman
ArchivelogRecordSpecifierSyntax::=::=PurposeA subclause used to specify an archived log or range of archived redo logs files for use in backup, restore, recovery, and maintenance operations.When backing up archived redo logs, RMAN can perform archived log failover automatically. RMAN backs up the log when at least one archived log corresponding to a given log sequence number and thread is available. Also, if the copy that RMAN is backing up contains corrupt blocks, then it searches for good copies of these blocks in other copies of the same archived logs.Specifying a range of archived redo logs does not guarantee that RMAN includes all redo data in the range: for example, the last available archived log file may end before the end of the range, or an archived log file in the range may be missing from all archiving destinations. RMAN includes the archived redo logs it finds and does not issue a warning for missing files.
