[Networker] Backup of Solaris files and Oracle (via RMAN) incremental ba

Hello all,

I'm maintaining an old backup procedure written by somebody else, notvery well documented and I'm having a hard time understanding aparticular aspect of NetWorker incremental backups.

The procedure backs up some flat files on a Solaris 10 machine, Oracleconfiguration files and RMAN backups of the Oracle instance (NetWorker7.2 client and NMO 4.2 packages installed on the client machine).The NetWorker 7.2 server has the client, driver, node and serverpackages installed.

Inside NetWorker, there is a client configured for this backup set(<clientHostname>), with a specific schedule created(<prefix>_backup_<clientHostname>), specific group(<prefix>_backup_<clientHostname>), save set (<saveSetTag>) and backupcommand (of the save* form).There's also a specific pool (<prefix2>_backup) with the aforementionedgroup attached (the save set <saveSetTag> is not attached to the pool).

The backup command is a shell script calling another Perl script andpassing the parameters received in $@ from NetWorker. The Perl scriptuses the NetWorker /usr/bin/save commands to backup some files from theserver and the Oracle configuration files (spfile, tnsnames.ora, etc.)and RMAN sequences to backup the contents of the database.

When I'm scheduling an incremental backup (without prior full backup),the nwadmin interface signals that no full backup of the saveset<clientHostname>:<saveSetTag> exist, which is correct. However, afterperforming the full backup, I get the same message, even though a fullbackup has been performed - the RMAN-generated files are saved on thebackup media as a <clientHostname>:RMAN:<rman_tag> saveset, which doesnot match the <saveSetTag> saveset. The backup command is sending theparameter -l (level) at full every time to the Perl script actuallylaunching the RMAN backup sequences (which have NSR_SERVER andNSR_DATA_VOLUME_POOL parameters correctly set), so the Oracle backup isallways done as full.What's even more strange to me is that this procedure was working in thepast, doing incremental backups on Oracle instances of hundreds of Gb,where the difference between a full and an incremental backup is easilyseen.

What am I missing here? Should I define the save set differently insidethe client defined in NetWorker, in order to recognize the<clientHostname>:RMAN:<rman_tag> savesets provided by the Perl script?


Thank you for your time,
Adrian
