When looking in OpsCenter it was observed that the domain_jobarchive table only had the masterServerId, clientName, and id fields for some NetBackup jobs. All the rest of the fields for these jobs did not contain any data.
When the job monitor is busy it does not send JOBFINALIZED messages. OpsCenter is dependent on these messages for receiving job updates. When the JOBFINALIZED message is not sent out the job updates are not sent to OpsCenter.
Due to a redesign of bpjobd in NetBackup 7.5, this issue should not occur with 7.5.x master servers.
If unable to upgrade master servers to 7.5.x please contact Symantec Technical Support and reference ET2976014.
