Hi.

The only time I've seen people have problems like this is when their host machine in under powered. Too few cores and/or not enough memory.

Remember, this is a 2 node RAC with a DNS server. The absolute minimum you should have is 16G of RAM, with all other apps closed. From a CPU perspective, if you open up task manager, or check top on a Linux/Mac host, and you see the CPU is being hammered, it's a safe bet to say it is still working, but just very slow.

Also remember the shared disks are just virtual disks on your physical disk. If you are using a hard drive, rather than SSD, it's going to be slower when dealing with disk.

Cheers

Nope, not the case. 24GB of RAM and dedicated CPU with SSD drive. I've used config file with no modifications just in case. I left more than 12 hours. Grid services seems to be running in the 1st node. After Grid install de 1st node restart by itself.

Thanks

OK. That's good.

Can you log into both RAC nodes and use "top" to see what the RAC nodes are doing? I would be interested to know:

• Are either of the nodes maxed out on CPU?
• Are either of the nodes swapping heavily? We aren't using enough memory really, so I would expect some swapping, but it would be interesting to know if something looks problematic.

Also, does everything look OK on the host machine?

FYI: I would not expect a restart of any nodes along the way.

BTW: I've just run a fresh build and it went through fine, so I don't think there is something fundamentally wrong with the build.

THANKS, New fresh build went smoothly. I added 8GB per node just in case. Now it works perfectly.

Thank You!

Awesome! :)
