We run our SOA suite dehydration store and error-n-audit databases on zones in T5120s. But since they are not highly transactional, we have not yet seen any issues. All the mission critical ERP systems are run on E20k or E12K domains. As for the number of DB writers, they are calculated automatically based on the number of CPUs that Oracle sees on a machine, which will actually be threads on a zoned box. You can limit DB writers by specifically setting the db_writer parameter.

Subject: Oracle10g running on Solaris Containers

Hello everyone,

We recently migrated few database ( and 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
