We have an M3000 single physical processor and 8gb of memory running Solaris 10. This system runs two Oracle Databases one on Oracle 9i and One on Oracle 10g.
As soon as the Oracle 10g database starts we see an immediate drop in system performance, for example opening an ssh session can take up to 2 mins. We are also seeing a very heavy processor queue and paging large, what appear to be, paging statistics.
This server has been hardened using JASS and the oracle user has been converted to a role.
Below is an example of a vmstat run - this was done with both databases up but not processing anything:
Just wondering if anyone has experienced the same or a similar problem.

Hello,
i have a a1000 connected to an e6500. There's a raid 10 (12 disks) on the a1000.
If i do a
dd if=/dev/zero of=/mnt/1 bs=1024k count=1000
and then look at iostat it tells me there's a kw/s of 25000.
But if i do a

Hello guys,
I have two servers performing the same disk operations. I believe one server is having a disk's impending failure however I have no hard evidence to prove it. This is a pair of Netra 210's with 2 drives in a hardware raid mirror (LSI raid controller). While performing intensive... (4 Replies)

dbix::class::storage::dbi::oracle::wherejoins
DBIx::Class::Storage::DBI::Oracle::WhereJoins(3pm) User Contributed Perl Documentation DBIx::Class::Storage::DBI::Oracle::WhereJoins(3pm)NAME
DBIx::Class::Storage::DBI::Oracle::WhereJoins - Oracle joins in WHERE syntax support (instead of ANSI).
PURPOSE
This module is used with Oracle < 9.0 due to lack of support for standard ANSI join syntax.
SYNOPSIS
DBIx::Class should automagically detect Oracle and use this module with no work from you.
DESCRIPTION
This class implements Oracle's WhereJoin support. Instead of:
SELECT x FROM y JOIN z ON y.id = z.id
It will write:
SELECT x FROM y, z WHERE y.id = z.id
It should properly support left joins, and right joins. Full outer joins are not possible due to the fact that Oracle requires the entire
query be written to union the results of a left and right join, and by the time this module is called to create the where query and table
definition part of the SQL query, it's already too late.
METHODS
See DBIx::Class::SQLMaker::OracleJoins for implementation details.
BUGS
Does not support full outer joins. Probably lots more.
