I have a case open with EMC Support right now for a similar issue, using NMO
5.0 and NSR 6.4.1.
When we run with the recommended setting of filesperset=1 for all three
sections of the RMAN script (archive log, data files, archive logs), it will
fail every time with the sequential file error for the Oracle instance and
client I have been using for the test.
The debug log files they have me collecting indicate that it is timing out
connecting to the NSR server for the client file index. If we run with
filesperset of 10/40/10, which has been our standard config, it only fails
intermittently. We need to run with filesperset of 1 to get better
deduplication on the Data Domain library.
We've been working on this off and on for a month. EMC engineering just got
involved but has no answers yet.

Subject: [Networker] NMDA Oracle RMAN backups fail only when when nsrexecd is
running
We're running oracle backups via NMDA 1.1 on Solaris x86, and we've
run into an odd issue. First, the client details:
$ uname -a
SunOS client 5.10 Generic_142910-17 i86pc i386 i86pc
$ pkginfo -x LGTOclnt
LGTOclnt NetWorker Client
(i386) 7.6.2.2.Build.651
$ pkginfo -x LGTOnmda
LGTOnmda NetWorker Module for Databases and Applications
(i386) 1.1 [LNMs_2010.Build.231]
The NSR server is a Solaris 10 sparc server running 7.6.2.2.Build.651.
The issue we see is that Oracle backups via NMDA succeed only when the
nsrexecd process is not running. When nsrexecd is running, we get the
following error in the RMAN logs:
RMAN-03009: failure of backup command on ch00 channel at 08/17/2011 15:57:04
ORA-19506: failed to create sequential file, name="09mk7rku_1_1", parms=""
ORA-27028: skgfqcre: sbtbackup returned error
ORA-19511: Error received from media manager layer, error text:
lnm_index_cfx_connect retry failed. See previous error messages. (3:3:11)
channel ch00 disabled, job failed on it will be run on another channel
We didn't have this issue with the older NMO 5.X package. So now we have to
start nsrexecd to do "normal" filesystem backups, and then stop it to run
the RMAN NMDA backups -- clearly not an optimal approach :-)
In case it's relevant, the client is a Solaris non-global zone. Let me know
if you need any additional information, but any insight is
appreciated.
Cheers,
Paul
