We need to do our production 11i upgrade to 12.1.3 . Now, in this scenario , during the upgrade process, I need to lay the r12 file system in the new application server.Rapid Install 12.1.1 doesn't support RAC installation, so you need to shutdown all instances and keep one up, lay down the software and do the upgrade, then once the upgrade is done bring the remainings instances up.
We have RAC in production, now how do I install R12 with pointing to both instances of RAC ? . SO, if not possible, during this time,
If, when running the upgrade driver, how can I change the connection string to point to both the instances ?
So, I will run rapidwiz using single node of the RAC and do upgrade using a single instance. After completion, how and what I need to change in the application in order to point to both the RAC instanceThe steps are covered in the doc referenced in my previous reply.
