Mayen,
I don't know if this is still an issue, but when we migrated to Solaris containers several years ago, we ran into problems with instances crashing when Solaris reallocated the number of CPUs for the container. In particular, Oracle didn't like it when the number of CPUs was decreased. That was usually followed by a crash and the timing of the crash was all over the place. It could happen immediately or hours later.
One of the reasons for going to Solaris containers is the ability to dynamically change the allocation of CPUs, memory, etc. We had to turn this off to keep Oracle stable. This may or may not be your issue, as Oracle may have fixed it, but we've never dared to try turning it back on.

Subject: Oracle10g running on Solaris Containers
Hello everyone,
We recently migrated few database (10.2.0.3 and 10.2.0.4) from Solaris 9 running on E25k to Solaris 10 running on T5120 running multiple zones. Entire directory structure was moved from old machine to new machine. Oracle relinking was successful.
Since then, database are crashing frequently. mainly process (pmon or
smon) would simply die. Unix sas could not find any thing. I could not
find any thing either.
One thing I noticed, on old machine I had only one dbwriter dbw0 but on
new machine I have upto six or seven dbwrites (dbw0, dbw1,....). No
parameter change have been made. I am not sure why this change in number
of dbwrites and if it has any relevance.
I have forwarded metalink note 317257.1 to UNIX sas.
Does any one has been running Oracle10g on Solaris containers? Any problems/issues?
Any help/pointers are greatly appreciated.
Thank you
Mayen
