NetBackup resource broker single threaded Sybase query/evaluations
Hello,
Has anyone here had performance problems with 6.5 masters running on Solaris with T5220 or T2 Sparc class processors? I have noticed that during periods of heavy job load the nbrb evaluation cycle, which appears to handled via a single threaded dbsrv9 process, can take forever and leave jobs stuck between requesting & granted resources states. Sometime for 15 minutes a time, depending on the job load.
I am familiar with nbrb.conf tweaks, however this doesn't make much difference in my environment where we have many disk-based destinations. Seems like in large environments, the master needs to be on a processor better suited for single threaded performance.
Thoughts?

Don't if already done this. But you can increase the performance of the database by going into /usr/openv/db/bin/nbdb select 2 "Database space and Memory Management" - 4 "Adjust memory settings" - 3 "Large Configuration".
Make sure got memory for the large configuration.
