Change 5977383300318 for thread 2 is in sequence #4

Question

Hi All,
the database was a single one on 10gR2
i was doing a cold clone from one instance to another, when running recover
"recover database using backup controlfile"
it was always looking for sequence # 4 but in the archive log i only have #2 and #3.
i do not have sequence #4 anywhere on the system.
can you suggest a solution for this?
Thanks in advance.

Hello,
When you Backup the database you should either:
1. Make a Cold Backup:
- Shutdown the original database and copy it's datafiles, redolog files, controlfiles, PFILE/SPFILE.
2. Make a Hot Backup:
- Set the original database in BEGIN BACKUP mode, then copy the datafiles, controlfiles, PFILE/SPFILE.
- Generate a last Archive log alter system switch logfile; and copy all the Archived log since the beginning of the Backup.
- Set the original database in END BACKUP mode.
In the first case, you don't need to make a Recovery.
In the second case you'll have to make a Recovery.
Else, you may use the DUPLICATE statement from RMAN:

Hope this help.
