  • Using the Pre-Upgrade Information Tool

Exercise 2 - Upgrading the Database

In this exercise, you will learn the following:

The easiest way to perform the upgrade is using the DBUA. There are certain situations where a manual upgrade needs to be done. The manual upgrade can be carried out for database versions 10.2.0.5, 11.1.0.7, 11.2.0.2 or higher. The tasks that are carried out in the manual upgrade are the same that are carried out using the DBUA. But for the prerequisite checks, the DBA is fully responsible before the upgrade takes place.
