11g on VMWare

159999Sep 29 2007 — edited Oct 1 2007
I understand that Oracle server is not supported on VMWare but this is just a test install and I am facing two major issues which I never faced in 10g under same environment. I have installed 11g RAC on a two node SLES 10 sp1 virtual machine. I am faced with two issues:

a) After reboot, the CRS doesn't start. It does not even start if I issue init.crs start command. After lot of experimentation, I found that after issuing init.crs start, the CRS cannot find the voting disk. However, if I rerun the root.sh script, the CRS starts up immediately. By itself the root.sh doesn't startup the CRS. I have to run it after running init.crs start. What does root.sh do to make CRS recognize the voting disk? Why init.crs cannot do the same? The disk permissions etc. are correct.

b) The virtual machines do not stay up for more than 30-45 minutes. They crash without any entry in CRS logs about node eviction. Is there a way to relax the timings so that even with missed heartbeats, the CRS would wait longer before evicting a node?

If someone has any insight, I would greatly appreciate. I had earlier tested the same setup with 10g RAC and did not face these issues.

Thanks

JRE may not be enabled in your browser. Check whether it is enabled or not?

You can verify that from 'Tools -> Internet Options -> Advanced -> Java (sun)'

I'm having trouble deciphering that message as well. ..Mostly because you did not copy/paste it.

The JVM being used by the browser is earlier than the version of javac you compiled the applet with.

So update the browser's JVM or use the -target switch of javac.

If you get a message you can't 'decipher', post it. Just saying you can't decipher it only wastes time.

I'm running Java SE 7, which should be the latest version of Java available. Does this mean I need to update my compiler?

Sorry that I keep asking these questions but I want to make sure my applets will run properly in the future.

No, it means that your browser isn't running Java 7, but has an older plugin.

Then maybe use the target flag when compiling so it's compatible with 1.5. Version 1.6 tops. Unless you really need to use all the new features.
