I have 2 Oracle servers installed. Data guard is configured on both the servers. I saw http://www.symantec.com/docs/TECH127889. Now I have Backups working fine on one of the servers and the other one fails with error unable to detect remote agent.
I would like to know how Installation of Data Guard would affect the Oracle Backups or in other words what makes it unsupported by Backup Exec.
As mentioned in the technote Oracle Data guard is not supported with Backup Exec. So what you are running is an unsupported configuration.
The backups may or MAY NOT work and that is the reason that even if they run it is not supported.
