Hi Group,
I have a RAC (10.2.0.4 on RHEL 5.3 Linux x86-64) cluster and we do a large
amounts of sorts and things in Parallel. I was looking at Fusion I/O cards
which are kept in the server. What I was thinking was, if I used a Temporary
Tablespace Groups and assigned users to this, would it be possible to store
1 temporary tablespace locally on each node (4 total), or does this have to
be on shared storage as well? If I can store them local, then I can use the
Fusion I/O device.
Our hardware rep is trying to sell our Linux admins this for swap, but the
problem is my boxes don't really swap as I have a large amount of physical
memory, but if I can use it for super fast sorts, then I might have
something. I prefer not to store my Undo or Redo though, since I want other
nodes to be able to reoer if something fails, but Temp doesn't need to be
shared if we use groups, or do we? That's the question.
Looking for some thoughts.
Thanks!
Tom
