Oracle may retain archivelogs older than the retention window – it does a purge
only if the FRA is running out of space.
That can explain why some servers have older archivelogs – simply their FRAs
are larger relative to the sizes of the backups and archivelogs.
You should be running a “CROSSCHECK BACKUP OF ARCHIVELOG ALL” {not “crosscheck
archivelog all”} because you want to mark Expired the *backups* of archivelogs
that are not available to restore from.
Once you do a CROSSCHECK and find that some backups are marked EXPIRED, you
might want to DELETE EXPIRED BACKUP OF ARCHIVELOG ALL

Hi Andrew,
This is a script I've inherited and won't be able to change till next spring -
and I do appreciate any improvements. However, this script has been working
fine in thousands of servers for several years. I'm thinking there must be
something about this particular server.
Even though the "restore archivelog validate" is asking for the last 2 weeks,
shouldn't it be able to run successfully even if there are only 2 days of
backups?
Am I misunderstanding or missing something?
Thanks

I'm not sure I understand the problem. Everything seems to be working
properly. You have a recovery window of 7 days and are asking for archive logs
14 days old, and they are gone as they should be. I don't actually see a
problem here.

Hi, ( note, cross posted in Oracle community Database Backup and Recovery )
I'm not super-versed with RMAN but am trying to resolve an rman issue on a
development server. The DB environment can be rebuilt if needed, but I'd like
to try and resolve this with a crosscheck command, etc.
The weekly rman backup script looks like:
run {
configure controlfile autobackup on;
configure controlfile autobackup format for device type disk to '%F';
configure retention policy to recovery window of 7 days;
allocate channel d1 type disk maxpiecesize=5G;
backup as compressed backupset incremental level 0 cumulative tag 'L0'database
plus archivelog delete all input;
restore database validate;
release channel d1;
delete noprompt obsolete;
restore database check logical validate;
backup validate database;
restore archivelog from time 'SYSDATE-14' validate;
host 'copy C:\oracle\product\12.1.0\dbhome_1\NETWORK\ADMIN\tnsnames.ora
C:\oradata\fast_recovery_area\';
host 'copy C:\oracle\product\12.1.0\dbhome_1\NETWORK\ADMIN\sqlnet.ora
C:\oradata\fast_recovery_area\';
host 'copy C:\oracle\product\12.1.0\dbhome_1\NETWORK\ADMIN\listener.ora
C:\oradata\fast_recovery_area\';
host 'copy C:\oracle\product\12.1.0\dbhome_1\database\pwd*.ora
C:\oradata\fast_recovery_area\';
}
list incarnation of database;
list backup summary;
list backup by file;
list recoverable backup of database;
report schema;
report need backup redundancy=3;
report need backup recovery window of 3 days;
The command "restore archivelog from time 'SYSDATE-14' validate;" is throwing
the below error:
RMAN> restore archivelog from time 'SYSDATE-14' validate;
Starting restore at 07-OCT-15
using channel ORA_DISK_1

...
Note, that "RMAN> restore archivelog from time 'SYSDATE-1' validate;" does work
successfully.
I did find and removed on obsolete backup set, but that didn't resolve the
06026 error.
I tried "crosscheck archivelog all;", but that does not resolve the 06026 error
during the restore archivelog validate.
Is there a crosscheck command or other command that would sync the catalog and
disk to resolve the 06026?
Thanks for all replies.
