[nbu123]

Master: SUN OS 5.10 NBU 6.5.6

Media Server /Client Server : Windows 2008   NBU 6.5.6

Client is itself a media sever.

SQL backups are failing with EC6 whereas File system backups are working fine.

Please find attached DBclient Logs....

Let me know if any other info is required

Key of this issue is time out of reading dbext logs.

readCommFile: ERR - timed out after 900 seconds while reading from D:\Program Files\Veritas\NetBackup\Logs\user_ops\dbext\logs\4668.0.1367389638

Questions:

Is this a new setup that has never worked before?

What is SQL version? Have you checked compatibility guide?

Are you aware of the fact that NBU 6.x is no longer supported?

Errors seen in dbclient log (13 instances of this error for different Db's):

Dbbackrec::PerformNBOperation: USER - Backup operation inhibited because database Edge_Billing is in standby state.

00:18:49.257 [10956.4668] <16> GetMappingForShMBackup: Unable to open shared memory (Global\NetBackup Media Manager SHM Info Path waboth9eodsba01-ebr_1367391510) to get shared memory information: (error 2)

I found 2 Unix-related TNs that suggest a permissions issue with /usr/openv/netbackup/db/config/shm folder on the db client-server. Windows equivalent: <install-path>\netbackup\db\config\shm 
On Windows server, the NBU Service logon account used for backups should have local admin rights as well as SQL admin rights.

Please start by checking Compatibility Guides:

NetBackup 6.x Application/Database Agent (CL):    http://www.symantec.com/docs/TECH43684 

NetBackup 7 Application/Database Agent (CL):    http://www.symantec.com/docs/TECH126904
