Know How! – IT Management Weblog

Today is “notfication day” I have to (re-) create several notfication subscriptions in OpsMgr 2007 R2 and tumble over some issues, which i have almost forgotten:

Note 1: Adding Subscribers for a existing subscription

If you add a new subscriber to an existing subscription, i recommend to delete ALL existing subscribers and then re-add them including the new subscribers. If you do no delete the existing subscribers i found out, that it is almost certain, that the added subscriber will not get notified…

Note 2: If you use Notification Command Channels, it might be useful to increase the maximum number of asynchronous responses

Maybe you will get an Alert:

The process could not be created because the maximum number of asynchronous responses (5) has already been reached, and it will be dropped.

Then you should consider increasing the number of responses, which can be run on the RMS. You can increase the number via this registry setting:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft Operations Manager\3.0\Modules\Global\Command Executer]
“AsyncProcessLimit”=dword:0000000a

But before doing so, i recommend to read the blog post from Clive Eastwood carefully: http://blogs.technet.com/cliveeastwood/archive/2008/04/16/some-more-command-notification-tricks-and-tips.aspx
