I found a TN that may help.
Please have a look at http://www.symantec.com/docs/TECH46255
The DLL mentioned in the TN is for NBU 6.0. The 6.5 DLL will probably be newer.
Have a look at the Overview section for problem description, then Resolution section (bearing in mind that the Adaptive Server Anywhere version and dll version will probably be newer - adjust steps accordingly):
Resolution:
The path to a critical DLL for allowing ODBC communication to the EMM database can not be found at the specified location. The DLL is called DBODBC9.DLL. Check to see if the DLL exists in the correct location, \<InstallPath>\VERITAS\NetBackupDB\WIN32\DBODBC9.DLL
If the DLL is there, check the registry to make sure it is pointing to the correct working path for this DLL:
HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI\VERITAS NB Adaptive Server Anywhere 9.0.1\ and verify the keys named Driver and Setup are pointing to the correct path. If they are incorrect, change them to reflect the correct path to DBODBC9.DLL.
Once the path statements have been adjusted, stop and start the NetBackup services:
1. Stop NetBackup services by running the following command:
<installPath>\veritas\netbackup\bin\bpdown
2. Verify all processes have been stopped by running the following command:
<installPath>\veritas\netbackup\bin\bpps
Note: A reboot may be necessary to fully eliminate any lingering NetBackup processes that might not terminate when the services are stopped.
3. Start the NetBackup services by running the following command:
<installPath>\veritas\netbackup\bin\bpup
