    We got this SCOM error last week along with a ton of the following warnings. Microsoft claims that this is a known issue that was supposed to be fixed with SCOM 2007 SP1 / SCOM 2007 R2, but I still encountered it running R2.

    This is caused by a high number of sql queries to the Datawarehouse database. The work around is to add an override for the Event Data Collector rule in the Data warehouse connection server scope.
    The Execution Attempt Timeout Interval Seconds property was changed from 0 to 6 and the Max Execution Attempt Count was set from 0 to 10. Restart the System Center service on the RMS and any gateway servers.

    I noticed one day that I stopped getting any SCOM alerts in my System Center Operation Manager 2007 R2 environment. As part of my troubleshooting I found a ton of the following warnings in the Operations Manager Event viewer. I contacted Microsoft tech support and discovered that my RMS was in maintenance mode. I had put my RMS in maintenance mode for 30 minutes when I did some windows updates, but it never come out of it. After stopping maintenance mode and re-starting the System Center Management service on the Root Management Server, alerts started coming in again. The Microsoft tech told me that you should never put your RMS in maintenance mode and when I asked to have some documentation where it said that, he said it does not exist. This a tip that they have discovered in their troubleshooting. During this time the RMS was unable to process agent requests, so the agent holds on to the notifications in a buffer until it can communicate with the RMS again. If you are getting this warning on the RMS there is a good chance that you lost any alerts that the agent was unable to store in the buffer.

    The Conficker worm aka Downadup worm continues to infect non-patched Microsoft computers a year after the initial outbreak. This worm scans your network and finds and infects other computers that are also not patched with the Microsoft MS08-067 critical patch. The worm can effect network performance since it floods the network with traffic while it scans  for other hosts to infect. It’s not in the news anymore since most companies have updated their systems, but just as many have not and are still vulnerable to attack. So get patched and update your anti-virus software.

    gamestream

    If you have purchased a graphic intensive PC game recently, such as Cryisis, you realize that  your computer runs the game like a choppy YouTube video. In order to get a better gaming experience you need to get the latest hardware, so a $60 game may end up costing you hundreds in hardware upgrades.

    Years ago when computing power was extraordinarily expensive, you had a server like a mainframe do all the number crunching serve out results to “dumb” terminals.  What if the graphics and physics calculations of today’s games were subcontracted to servers that did the heavy lifting. As computer power reaches pennies per Ghz and unlimited internet bandwidth increases steadily, the next evolution in gaming is in game streaming and subscription.

    Imagine subscribing to  the latest graphically intensive game that just came out over the internet. With the streaming model, video is streamed to your desktop while the game is running on a remote server at high resolution and with high game details on. That means your PC doesn’t have to run the latest hardware to play the game the way it was meant to be played. A recent article has revealed the OnLive will attempt do just that.

    Of course this would only work if you have the bandwidth to support it. The internet backbones are currently being upgraded, but higher internet speeds will likely cost you more as well. Another road block would be the ISP’s proposed cap on your monthly bandwitdh. If the unlimited internet bandwitdh model changes, entire business built on internet communcations will suffer, including the upcoming game streaming.

    Blackberry Curve

    I just got a Blackberry Curve and my first impression is not how cool it is, but instead how much the battery life sucks. I have to charge it up on a daily basis or the battery dies. I got a new battery and I charged it for 24 hours and I still don’t get the battery life that I expect to be getting. If I forget to charge it at night it’s dead by morning.  I’m on the Sprint network and I am connecting to my home WiFi for local internet connectivity. I leave it in the holster which I thought was supposed to use less battery. I was wondering if there might be some options I can change to conserve battery life. As I was searching I found an article about a company called M2E Power that is making a device that charges your cell phone or iPod while you walk. I thought this was a great concept considering how many devices that require batteries are for people “on the go”.
