I came across a great article on TechNet which is essentially a compilation of useful SCOM information, it includes everything from the basics and key concepts, to deployment guidelines and information on how to configure and use different features.
Update Rollup 4 for System Center 2012 Service Pack 1 has been released:
Note: This Post from Microsoft hi-lights issues with the SCSM UR4 and explains why it was pulled from the download center. “Our team realized today that no Debug Symbols were available for the MSI. Giving us no ability to support any issue that may occur. We are asking everyone that has downloaded it as of now to please “NOT” install UR4 into your Service Manager 2012SP1 environments. If you have already installed the update, we ask you to please bear with us while we sort out the issue. “
.This update contains many fixes listed below, particularly for SCVMM and overall seems like a good update, there are 20 updates for SCOM and the SCOM Unix agent , however as usual test before implementing as these updates can cause their own complications.
