Installing 9i...use it as 8i.
we've sold our product, and the client wishes to use 9i instead of 8i which we've used until now.
Our product is nearly changed to work with the dll's of 9i, but there's something I'ld like to ask.
For the moment I'm not really familiar with 9i (I'm OCP8iDBA), I'm going to take the '9i New Features' course next year. Is it possible to install 9i "BASIC" -->like a 8i
and afterwards make adjustments to use f.i. Real Application Clusters, or is this an intensive operation?
I am not sure if you can setup a non-RAC database, and then "convert" it to RAC...but I can share this with you:
We just went live with a 4 node 9i RAC setup. Initially we created 2 instances (cause we only had 2 servers)...then we added 2 more instances (when the 2 add'l servers came in).
I would suggest creating the database as a RAC instance, but have only 1 setup. When you have add'l machines, and you are comfortable handling multiple instaces, you can expand RAC. But even to setup the 1st one is going to take some RAC knowledge. I would suggest going thru some pretty complete DOCs on Metalink...to setup RAC. There are DOCs for each OS type.
Maybe what you are looking for is the compatability parameter, which allows you to limit 9i to the features of an earlier release.
Here is a (badly formatted) quote from the Oracle 9.2 Database Reference documantation ...
COMPATIBLE allows you to use a new release, while at the same time guaranteeing
backward compatibility with an earlier release. This is helpful if it becomes
necessary to revert to the earlier release.
This parameter specifies the release with which the Oracle server must maintain
compatibility. It allows you to take advantage of the maintenance improvements of
a new release immediately in your production systems without testing the new
functionality in your environment. Some features of the current release may be
When using the standby database feature, this parameter must have the same value
on the primary and standby databases, and the value must be 220.127.116.11.0 or higher.
The default value is the earliest release with which compatibility can be guaranteed.
The value of COMPATIBLE must be set to 8.1.0 or higher in order to use stored
columns of UROWID type. You can use ROWID pseudo columns for index-organized
tables regardless of the parameter setting.
Parameter type String
Syntax COMPATIBLE = release_number
Default value 8.1.0
Parameter class Static
Range of values Default release to current release
Multiple instances must have the same value.
