Hello All,
Catalog backup of one of our master server is getting failed with 2.
Master Server ---Linux
Master Server netbackup version----NetBackup-RedHat2.6 7.1.0.4
I am getting the below error when I ran the command ./nbdb_admin -validate NBAZDB
SQL error (-832) -- Connection error: Insufficient system resources - failed to allocate a SYSV semaphore
SQL error (-832) -- Connection error: Insufficient system resources - failed to allocate a SYSV semaphore
SQL Anywhere Validation Utility Version 11.0.1.2745
./nbdb_admin -validate BMRDB
Can't identify database BMRDB.
Solved! Go to Solution.

failed to allocate a SYSV semaphore
OK - This should be easy to fix. Take a look at this tech note and apply the kernel tunables.
http://www.symantec.com/docs/TECH203066
You need to re-start Netbackup (better to reboot) for changes to apply.
I usally apply these kernel tunabes to /etc/sysctl.conf and apply with with "sysctl -p"
# Netbackup tuning variables.

How many jobs are getting activated for Catalog backup?
Is parent or child job(s) failing?
Please show us all text in Details tab for all Catalog parent and/or child backup jobs.

Hello Marianne,
Child jobs are not generating.
Please find detailed status of parent job.

Did you resolve the SYSV semaphore you wrote about before ?
This look like a new error.

Problem has been around for a couple of weeks now.
No a big priority??
I am wondering about the health of NBU relational databases on this master server...
