Automated Upgrade Tasks

Automated Upgrade Tasks
After completing the pre-upgrade steps, DBUA automatically performs the following
tasks:
■ Modifies or creates new required tablespaces
■ Invokes the appropriate upgrade scripts
While the upgrade is running, DBUA shows the upgrade progress for each
component. DBUA writes detailed trace and log files and produces a complete HTML
report for later reference. To enhance security, DBUA automatically locks new user
accounts in the upgraded database. DBUA then proceeds to create new configuration
files (initialization parameter and listener files) in the new Oracle home.
