While we've never done any RMAN database backups (we simply instruct the
DBAs to dump their tables to flat files if they want their data backed
up!), Networker 'scheduled' backups are normally initiated by the
Networker Server via an enabled Group that the selected client is in...
and it will do an Index backup unless you have the Group set with a 'no
index' option. We never use CRON on the client to initiate a backup... A
manual backup is initiated by someone logged into the client via either
'save' or a Database/Application Module, and you do have to specify the
desired media pool, otherwise the server labels a tape in the 'Default'
pool and writes to that (with no index backup). Most folks turn the
Index backup off on their groups and run one group per day (we named
ours 'Index') to backup nothing but the Indexes, this does have to be
done from the command level on the Server via 'savegroup -O -l full
groupname' as the NMC does not really provide a way to configure a group
to do this automatically. Since our NW server is windows based, we use a
scheduled task to initiate the Index backup group (MS equiv to cron)
each morning @ 8 am after all our nightly backups have finished.

Subject: [Networker] NMDA RMAN Backup
All,
This is my first time setting up the Networker and trying to understand
scheduled backup from the client vs. manual backup. I guess both are run
from DB server except that scheduled backup are run via crontab and
manual is running the script on demand from command line. Did i capture
this right.
We have a 3 node RAC cluster (11gr2) on RH5.5, Networker 7.6 sp1 and
NMDA 1.1. I have networker client and nmda module on all DB nodes
installed and have the configuration file nmda_oracle.cfg configured and
created rman file (see below). Now, how to schedule this task from DB
node. Is it as easy as wrapping the rman scripts in a shell script and
calling that from cron? Anything else i should have it configured before
running this ? Also i read that client index files and bootstrap will
not get backed up if backup are initiated from client. How do i back
them up after successful RMAN scheduled backup? Thanks in Advance!
