Today (Saturday) We will make some minor tuning adjustments to MySQL.

You may experience 2 up to 10 seconds "glitch time" when we restart MySQL. We expect to make these adjustments around 1AM Eastern Daylight Saving Time (EDT) US.

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

Does the fmadm command show any problems. If it is a hardware fault of almost any type, you can get information about it. Run fmadm from the global (or root) zone as the root user. If you see problems open a ticket with oracle support. Sometimes oracle problems cross software->hardware boundaries.

Hi,

Thanks for reply.

Oracle have been involved at DB and o/s level with no luck so they have reviewed zones and explorers (not 100% if that will contain fmadm info) but no luck as issue is not repeatable and random. I will check with our SA about running fmadm on global zone to see if that throws up anything unusual.

Thanks
