Hi,
we are using multiplex archived logs.
First archive_log_destination is on the local hard disk.
Second destination is on the novell file server (via nfs mount)
The database will be backed up with rman. This is a full backup (datafiles + archivelogs). After backup, all archivelogs will be deleted from hard disk (delete obsolete).
But rman seems to hang. Rman allocates a channel 'type=disk', but after command "delete obsolete" rman seems to break.
I guess, rman has a problem with nfs mount.
Which parameters are necessary for nfs mount?
Best regards
Marie

There are no error messages.
The output is:
RMAN> delete obsolete;
RMAN> retention policy will be applied to the command
RMAN> retention policy is set to redundancy 1
After this rman will be aborted.

That mean the command is running successfully!
Delete obsolete only used to delete the backup sets. It will not delete the archived logs. If you want delete the archived logs, you can use "backup archivelog all delete input".

If the backup job runs seccessfully, the output is:
RMAN> delete obsolete;
RMAN> retention policy will be applied to the command
RMAN> retention policy is set to redundancy 1
using channel ORA_DISK_1
deleting the following obsolete backups and copies:
Backup Set ....
Archive Log .....
deleted backup piece handle=....
RMAN> **end-of-file**
Recovery Manager complete.
Thank you
What rsize/wsize means? Are the values default?

rsize=8192,wsize=8192
This will make your nfs connection faster than with the default
buffer size of 4096. (NFSv2 does not work with larger values of
rsize and wsize.)
for detail information, run "man mount"

Perhaps that's only because these is no obsolete backup sets.
Try to run report obsolete to see if there any obsolete backup sets.
