Enterprise Manager 10.2.0.5 has Oracle VM Manager onboard
By Rene Kundersma on Mar 14, 2009
Today, I have tested the new Oracle VM Management capabilities that Enterprise Manager Grid Control (EMGC) 10.2.0.5 has.
The existing Oracle VM Manager, is rather quick and light weight, so you will probably think why do we need EMGC for that.
Well, think about the following advantages:
- All in one management console
- EMGC runs also on Windows, so now you can manage Oracle VM from windows, which was not possible before
- You can set thresholds
- Use the Single Sign On that EMGC has
- Use the security features EMGC has
- Setting notifications and alerts so that admins can manage on exception basis.
- Context based flows (even if manual currently).
For example, change the vCPU on para-virtualized linux guests if database diagnostics (ADDM) suggests additional CPU
- Specific EM features like Configuration compare, search, policies for host and hypervisor. The policies can span multiple tiers and can be user defined. Example, do not run mixed workloads (database and middleware) on the same Hypervisor.
- Guest patching with integration with Unbreakable Linux Network (ULN)
Some quick requirements had to be filled in before I could begin:
- install a one-off patch to the OMS (patch 8244731)
- install VnCViewer into $ORACLE_HOME/j2ee/OC4J_EM/applications/em/em
- also had to be sure Oracle VM Agent was updated to version 2.2-70 or higher.
This all went smoothly. Please note that it makes sense to install the patch and the VnCViewer at the same time when the OMS is down.
Please read note 781879.1 for full details (as information may change and there is only one singe source of truth)
First I had to create a server pool. After creating a server pool, it was just a matter of making the Oracle VM Server aware of the Vm images I already had on disk.
And exactly for this was an option, which you can see in the capture below.
This is the place where you can see all the VM Images discovered in your virtual server pool.
After this, it is just a matter of selecting the images and "importing" them into your vm "admin" page.
From here you can do the usual; start, stop, pause, suspend, clone and get to the console.
To me this seems a new step taken for EMGC to be the complete management framework.
