I am responsible for coming up with a quote on Web Servers for a contract we have with the State.
We are receiving servers any day now which I did not help configure. They are 1200s coming with
TruCluster SW (Don't know if it's ASE or PSE). It had been planned to run TruCluster, Oracle Parallel
Server and LSM, with the usual memory channel, private ether channel,etc. They will be running a
critical, albeit not 7x24 Oracle database on each cluster member. I understand that to fail-over the
database, I will need TruCluster PSE, not ASE.
I was going to spec. the Web Servers (which will run Oracle App. Server, and Developer Server) to
use TruCluster ASE (No database here). OAS performs it's own load balancing and fail-over of it's
remote nodes (2 out of 3). If the master server were to crash, they would all be down. Given that we
have Compaq Support, and that I can RAID 0/1 the disks to prevent a disk failure crash, I am pretty much convinced that I have a cheaper, faster Web server trio( I am settled on three ES40 1GB) if I don't run
any cluster software. I mean, all this cluster software related software has to take CPU time, and would
be prone to break or have problems. I see a TruCluster ASE problem currently on the list even now.
Since the database server HW/SW has already been purchased, I guess I'm obliged to run it, and it
is semi-critical.
Here's my questions:
Are there any benchmarks of before and after of a set of database servers each running their own instance
standalone vs. TruCluster sharing resources?
Would I be losing clock cycles running all the cluster related SW vs. a half day of downtime every 6 months
or so?
What are the best books covering set up/tuning of TruCluster ASE, PSE ?
Is there a good reference of exactly how TruCluster works? How it keeps track of processes, registers, etc.?
P.S. As you may have guessed, I've never even seen TruCluster/Oracle Parallel Server at work.
Thanks,
