In Unity 3.x if the exchange server fails while unity is up messages are stored and forwarded to exchange when the server comes back up. If the exchange server is down, and unity is down, unity will not start without the exchange server? Is there a way around this? It may take a while to recover Exchange from failure.<br><br>
Based on the 3.x question and answer above. Will the system start in UMR mode? Or does it require exchange to start and then if exchange fails it goes into UMR mode?
The UMR was designed to kick in if Unity was running and Exchange hit the dirt.
Unity wont start if the Exchange messaging services of the server you select in part 2 setup is down (doesn't matter if this is on or off box Exchange). There's no easy way to get Unity to start up in UMR mode since so many components attach to Exchange and expect it to be there at startup time (the MAL and the notifier for the most part are your problem components here).
There MIGHT be a way to manually force Unity to not try to initalize these and come up in UMR mode if your Exchange is going to be down for a while. I'll run a few tests...
Jeff, the exchange server ran out of disk space. We are in the process of repairing exchange but it is taking a considerable period of time for this to complete. Trying to at least get Unity up into UMR mode so we aren't completely without while exchange repairs.
OK, talked with the messaging boys and just tried this out on my 3.1(2b) server with Exchange installed locally (I forced all Exchange services to "disabled" to try it) and it seems to work OK. You need to manually edit/add keys to the registry for this to fly.
First, go to: HKLM>Software>Active Voice>AvWm>1.00
and add a new DWORD key called "All Servers Down" and set its value to 1.
Next, got to: HKLM>Software>Active Voice>Doh>1.0
And edit the "LogonDefault" value to be 3 instead of the default of 7 (this forces Unity to not try to connect to the messaging service)
Finally, go to: HKLM>Software>Active Voice>UMR>1.0
and add a new DWORD key called "EmulateExDown" and set it's value to 1.
Unity should come up in UMR mode then. Of course when you're Exchange server is healthy again, you need to undo these changes. Let me know if that works for you...
You can set the first and third values to 0 but the second needs to be returned to "7".
