ARCserve 6.61 registry settings

[cscomm]

I've recently started working with an Oracle 8.06 database which is being backed up using ARCserve 6.61 on Windows NT4.

The registry setting (HKEY_LOCAL_MACHINE) for ARCserve is :
SOFTWARE
Computer Associates
ARCServeIT
DSAgent
CurrentVersion
Agent
Dbaora7@

All documentation that I've read (most of it less than helpful) indicates that Dbaora7@ should be followed by SID name so I'm concerned that ArcServeIt is not installed properly. Can anybody confirm that this is valid setting and if not, how do I fix it ?

Any advice or suggestions will be greatly appreciated.
