Home -> Community -> Mailing Lists -> Oracle-L -> Re: Parallel Server definition please.
Ron,
Are you using OpenVMS?
Simply installing Oracle onto shared disks is not OPS. Two (or more) =
instances running at the same time on different nodes accessing the same =
datafiles is OPS.
When I was running Oracle on a VMS cluster, I installed the software =
from one node onto the shared disks. This installation was accessible to =
all nodes, which meant that all nodes shared one common ORACLE_HOME. Then = I could start up databases on each node, using the same Oracle executables.= I ran test databases on Node A, and production databases on Node B. The =listener.ora had entries in it for two listeners - one for each node. I = never had two instances sharing the same datafiles (but that would be = possible if you installed and configured OPS). If one of the nodes = crashed, I could modify a few configuration files and bring up all of the = databases on the remaining node.
Let me know if you need more information.

List,
I have been reading the information provided by Oracle about parallel =
server option and I have confused myself (easy task lately).. Oracle =
states that Parallel Server Option allows 2 instances to access the same =
database at the same time. No problem understanding that part. We have an =
Alpha Clustered box that has 2 cpu boxes sharing the same os disk, =
multiple controllers and paths to the database disks. Is this the same as =
Parallel Server option? I would have to set each box up with a different =
IP address in the listner to allow access to both cpu boxes.
I am confused and need direction to clarify the answer.
Another option would be to use 1 cpu box IP as the development and the =
other as the production and then set up the listner to work in that =
manner. But what about the instances? there is 1 os drive for the 2 =
servers and where do I install Oracle because there is only 1 disk farm =
accessable to both cpu boxes?
Have I confused you too?
