Cyral, The frame is nothing more than the component
that holds the equipment. Oracle can support upto 256
instances in a RS6000/SP environment. I have setup 16
instances on 16 nodes in SP environment and have seen
upto 100 instances on 100 nodes. This is the long
answer to you question which is
Hi
I am sorry if someone has replied this
But can someone PLEASE tell me
if IBM supports OPS
across their SP frames.
or only support OPS WITHIN SINGLE SP frame?
Thanks

Actually, failover (TAF - for connection, session, and select) works fine
without MTS. I've built six 8i OPS systems in the last year or so using TAF
without MTS. (None had direct Java clients though.)
MTS is not required for the older multiple

Hi,
on AIX platforms, Oracle actually uses it's post wait driver
architecture.
It's a substitute for the operating system's semaphores. The background

Gopal et al,
One of the main differences between Oracle on HP-UX/Solaris/Sequent and
Oracle on IBM is their use of the Post-wait driver which uses a
'test-and-set' lightweight mechanisn instead of semaphores. The other
difference (in this OS

Don, failover, dispatcher cross registration and server load balancing
require MTS. Second, I'm not on AIX, that is why I was guessing about
semaphores.

Hi,
You are right. IBM uses a light weight process
(post wait driver??) instead of typical System V
semaphores. It is dynamically allocated and

sys config files (Right John??)

Hi
it's the first time I'm going to install an OPS
(Oracle 8.1.6 and AIX 4.3).
What things should I take care of? (patches, some
tips, etc)
Where can I find some documentation (besides Oracle
Concept Manual), can someone point me good docs?
TIA

Sorry I forgot to ask this one too:
In the manual says that one OPS advantage is High
Avaiability, now, in a client-server application,if
node1 goes down, how do clients that ussually
connect to node1 access the DB now?
How do they know that node1 is down and that now
they have to connect
Hi Mladen Thanks for the answer.
I'm already doing some reading...
I'd like to ask you some questions about your answer
Here I go. Please be nice if I'm wrong
1)Log threads have to be private to each instance,
right? there's no Public thread I think.
2)Is it usual to use PUBLIC rollback
. Remember the following phone number: (800) 223-1711.
Take vacation when you're done.
