We are trying to install two T4-1 in a ORAC configuration, when there are more than eight concurrent processes, there overall load increase and the database is frozen.
Do you know some best practices for this configuration?
In particular it is hard too see if you have a database issue or a server related issue; and it is not obvious what 'Frozen' means.
Itis probably worth ensuring your servers are fully patched up to date with firmware, OS and database software patches; and raise a support call to Oracle if problem persists.
Are you doing LDOMs or just installing on the base Control Domain.
T4-1Bs come with Solaris 11, are you using that or Solaris 10?
If you're doing LDOMs, then have you given more than 1 Core to each LDOM? It is highly recommended to have more than 1 core, if you're Db is going to be heavily hit.
Check your patch level. There were some issues on Solaris 10 till we went to atleast Generic_147440-10 (Feb 2012 patch set).
I'm running Oracle RAC on T3-1Bs on LDOMs. The issues that are known for Oracle 126.96.36.199 are
1. Make sure that your OCR/OVD data group (Voting / Quorum disks) on ASM are set to "Normal" redundancy, even if you have external redundancy.
2. Make sure that your data groups are mounted on both nodes.
3. Check your Swap space as well. What did cluvfy tell you when you tried to install the cluster? Sometimes there are things in there that are ignorable, but they'll come to bite you.
Overall, the Cores, Memory, Swap and Patch level will probably play a larger role than anything else.
