Home -> Community -> Usenet -> c.d.o.server -> Re: Can OFA and multiple instances lead to DBWR contention
Please expand on that thought. Why would numerous SIDs be a VERY BAD
IDEA.???
We have IBM's M80 servers. They have multiple processors, 8 Gig of RAM, and
configured on Shark disk. One instance on this server would have little to
no load on it. On some of our smaller servers we have multiple instances
because they are either small or have very little activity. Are you saying
each of these should also be on seperate servers????
