We had a similar issue with NFS mounted file systems and soft links, specifically the soft links for Veritas Quick I/O. We got around it by bypassing the links and registering the actual file names. The problem had to do with how the underlying protocol (I think it was UDP) is used by the rman executable. It's supposedly fixed in a later release of the microcode we are using but were not that brave.

I have been configuring RMAN to back up to disk on a Compaq Tru64, Oracle 8.1.6.

I have my script running successfully. Then the sys admin configures an NFS-mounted drive on the target system and asks me to write to it instead. When I do, I receive the message:

rMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03007: retryable error occurred during execution of command: backup

RMAN-07004: unhandled exception during command execution on channel d1 RMAN-10035: exception raised in RPC: ORA-19504: failed to create file "/rman/lpi
p/df_t464975695_s3_p1"
ORA-27040: skgfrcre: create error, unable to create file Compaq Tru64 UNIX Error: 13: Permission denied RMAN-10031: ORA-19624 occurred during call to DBMS_BACKUP_RESTORE.BACKUPPIECECRE
ATE I recalled that CREATE TABLESPACE is a good criteria of whether RMAN can back up to a disk, so I tried that and was successful. I also at the command line used touch to create the exact file RMAN was unable to. I searched Google and Metalink and found nothing that applied. I feel it has something to do with the NFS setup since I can write to regular disk just fine. Are there any configuration gotchas with NFS? I'm out of ideas. Can anyone give me a hint?
