looking for simple recovery scenario.
We have a 60GB 10gR2 database on ASM. A third party web application runs on this database. The application's version is old needs to upgrade to the latest version.
In order to upgrade I have to run about 24 sql scripts which has several DDL and DML statements against the database.
I have a full RMAN backup of database and archive logs before I start running the upgrade.
If something goes wrong during the upgrade, how can I go back to the previous state of the database i.e., as if I didn't run any upgrade scripts and it should be same as the last full backup?
