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:
I agree with Jill, one Oracle DB in 8g ram is pushing it, much less two running different versions of the Oracle DB. I didn't think you could get an m3000 with 8g ram anyway, are you somehow zoning this server to share the resources or has someone replaced the ram with a smaller amount?
Just a quick note for macOS users.
I just installed (and removed) Parallels Desktop 15 Edition on my MacPro (2013) with 64GB memory and 12-cores, which is running the latest version of macOS Catalina as of this post. The reason for this install was to test some RIGOL test gear software which... (6 Replies)

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)

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
