MetaLink Note:290985.1 Incomplete RMAN Recovery gives error ORA-01547



Symptoms
RMAN recovery with an 'until' clause giving errors:

RMAN-11001: Oracle Error: ORA-01547: warning: RECOVER succeeded but OPEN
RESETLOGS would get error below
ORA-01152: file ... was not restored from a sufficiently old backup
ORA-01110: data file ............


Cause
In order for the database to open after recovery, the datafiles must be 
consistent. If incomplete
recovery is performed, the recovery must be (at least) enough to make the files 
consistent. With
online backups, because the files are changing as the backup occurs, recovery 
must apply all archives generated between the beginning through the end of the 
backup.

The main error is the ORA-01152. This occurs because one file is ahead of the 
others at the requested recovery stop time.


Fix
To implement the solution, please execute the following steps:

1. Reexecute script using a longer recovery with the 'set until' clause.

If using 'SET UNTIL LOGSEQ' consider the definition of 'set until logseq' from 
Oracle9i Recovery Manager Reference, untilclause:

"Specifies a redo log sequence number and thread as an upper limit. RMAN 
selects only files that can be used to recover up to but not including the 
specified sequence number. For example, REPORT OBSOLETE UNTIL SEQUENCE 8000 
THREAD 1 reports only backups that could be used to recover through log 
sequence 7999."

In short, be sure the LOGSEQ specified is one greater than the last one created 
after the database backup completes.
