Solaris 11.2 x86 Local Zones for Oracle RAC database, intermittent Memory corruption of db

Hi,

I was wondering if any Solaris fellow out there has dealt with running Solaris 11 x86 on Local Zones for Oracle RAC (which may or may not be relevant to issue), running on HP gen h/w. Every so often could be weeks between issues or some times days, there will be a memory corruption and db block read error, sometimes the block is reread from disk by db s/w and found valid on reread other times there will be real corruption. Is there any other person who has experience similar issues on Solaris 11 x86 running Local Zones. I can't see any issue at san , db or o/s level to point to an issue, also issue is not repeatable but random in nature so proving very difficult if not impossible to diagnose root cause.

Was starting to think maybe issue could be at h/w or bios level, maybe power management of CPU.

BTW i'm not a SA.

Thanks

NAME

       install-solaris - install the Solaris operating system

SYNOPSIS

       install-solaris

       install-solaris	invokes  the  Solaris  Install	program. Depending on graphical capability and available memory at the time of invocation,
       install-solaris invokes either a text-based installer or a graphical installer.

       The following minimum requirements for physical memory dictate which features are available during installation:

       For SPARC machines:

       128 MB

	   Minimum physical memory for all installation types

       128 MB

	   Minimum physical memory required for windowing system

       384 MB

	   Minimum physical memory required for graphical-based installation

       For x86 machines:

       256 MB

	   Minimum physical memory for all installation types

       256 MB

	   Minimum physical memory required for windowing system

       512 MB

	   Minimum physical memory required for graphical-based installation

       In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number  of  fea-
       tures available.

       install-solaris	exists	only  on  the Solaris installation media (CD or DVD) and should be invoked only from there. Refer to the  for more
       details.

       install-solaris allows installation of the operating system onto any standalone system. install-solaris loads the software available on the
       installation media. Refer to the  for disk space requirements.

       Refer to the  for more information on the various menus and selections.
