Default Disaster Recovery and Restarting Services

Please Login to Remove!

Hi All,
I seem to remember something at WES '07 about a DR plan where if your BlackBerry services went down, a secondary server would detect the failure and start it up on the backup server. Now the problem is that I can't seem to find my notes about it. Nor can I find it on the TSupport site. Nor can I find it here.

Anybody remember what I'm talking about? They had a cool onscreen demo showing how if a service failed on server BES01 (like Policy Service), BES02 would then automatically detect the failure and start that service on BES02. WES folks said the mechanism for this process could be run as a Windows Service and no 3rd party software was required. (Like Neverfail.)

So I've done my searching here and at TSupport and didn't find what I'm looking for. Little help? Thanks.

If your talking about the session you and I went to. I'm pretty sure that's in BES 5.

By Thursday morning, they were starting to blend together.
Didn't they show an animated PowerPoint demonstrating the failover process and how it could be done via Windows Services? Was that BES 5? If so, I can't wait that long. Might have to budget for Neverfail. Good think I know some people using it; they can provide a reference.

You could create some scripts that will check a service status along with performing actions based on results ... a homegrown automatic high availability failover if you will. That said, if you really need something like this I'd go to Neverfail group.

Hey Darth, that was BES5, was a good demo that got me excited about Argon. Hopefully it won't be too delayed, I am looking forward to this feature.

I agree, that was the demo on BES 5 (Argon). Now the seminar yesterday mentioned using windows cluster to mitigate till then. ( I assume 2008 Windows Server)

We are reviewing Neverfail as an option also.

Default Doubletake ?

anyone heard of them ??

i am comparing to neverfail, but
i understand that if bes services fail,
all mailboxes must do a "resync" which will take a while
dont think neverfail can do that can they ??

Neverfail is only available for Exchange and Domino. BES on these two mail platform work differently. From the Domino side, yes Neverfail can do it because you replicate the database that keep track of this info to the secondary server.

He's an Exchange user, it seems. The "resync" process is actually referred to as a "rescan" process, where all mailboxes are rescanned for updates. While RIM says this takes "a while" to complete, I find real-world message flow beginning within seconds to minutes with full capacity brought back within 20 minutes for all users. This is in an 8-server BlackBerry Domain with roughly 500 users per server. I'm sure if you have a 2000-user server, there may be a bit more time involved. Rescans can also vary based on hardware for the BES, hardware for the Exchange servers, and network latency between BES and Exchange (our Chicago users on New York BES servers take a little longer to initialize than the NYC users, for example).
