[AGENT++] Agent++Win32 and Set Operation Failure with Multiple Variable Bindings

[Dave White | Networking]

Hi Frank,

Our problem is with a Windows Extensible Agent DLL.  I realize that this is a
proprietary Microsoft protocol, but Agent++Win32 has implemented it with the
benefit of AgentX++.  It seemed to me that AgentX was processing the requests
one VB at a time.  However, if AgentX attempts to group VBs already, then any
fixes should be limited to Agent++Win32 alone, correct?  This is a problem
that we need to correct.  Do you have suggestions or ideas about what
functions/methods needs to change?  Any other ideas you have about what needs
to change, and how, would be helpful.

Thanks,
Dave

Hi Dave,

Do you refer to AgentX subagents or Windows Extensible Agent DLLs?
For AgentX all VBs of a SET request (served by a particular subagent )
are always passed within one AgentX PDU to the subagent. So this is
compliant to RFC 2741.

For Win32 Extensible Agent subagents, VBs are always passed individually
by the Agent++Win32 master.  Since this "protocol" is not AgentX I see
not why it should be compliant to the AgentX RFC.
Passing the VBs at once should be possible though, however this would
make the current framework a bit more complex. If you need such a solution
urgently then please contact me by email.

Best regards,
Frank
