Increasing the filesperset will result in fewer NetBackup savesets - less files 
to scan when NetBackup does its cleanup.  Also, make sure the format parameter 
is correct .

Can you explain more about what this will results in? I am not so familiar with 
oracle. Will it backup more often or more seldom but with bigger "chunks"?

 

Should we do these changes in the archive log scripts on each oracle client?

2 changes with regards to archive logs:

 - set the filesperset parameter back to 20

 - changed the format parameter to "oracle_arch_%p_%s_%t"

We run 4 channels four our oracle archive log backups.. It backups 1000-2000 
transactions a day...

 

How did you solve your problems?

 

Thanks,

We had a similar problem with our master server ( rp4440) that backs up oracle 
databases.  Found that the rman script *.rcv had the filesperset set too low ( 
we had turned it down from 20 to 5 for the archive logs), causing hundreds of 
backup images.  This resulted in the disk I/O being high when the cleanup ran, 
and loads of bpdbm processes.
