DBUA will then prompt you to back up the database as part of the upgrade process. If you
have already backed up the database prior to starting DBUA, you may elect to skip this step. If
you choose to have DBUA back up the database, it will shut down the database and perform an
offline backup of the datafiles to the directory location you specify. DBUA will also create a batch
file in that directory to automate the restoration of those files to their earlier locations.
The next step is to choose whether to enable Oracle Enterprise Manager (OEM) to manage the
database. If you enable the Oracle Management Agent, the upgraded database will automatically
be available via OEM.
You will then be asked to finalize the security configuration for the upgraded database. As
with the database-creation process, you can specify passwords for each privileged account or
you can set a single password to apply to all the OEM user accounts.
Finally, you will be prompted for details on the flash recovery area location (see Chapter 14),
the archive log setting, and the network configuration. A final summary screen displays your choices
for the upgrade, and the upgrade starts when you accept them. After the upgrade has completed,
DBUA will display the Checking Upgrade Results screen, showing the steps performed, the related
log files, and the status. The section of the screen titled Password Management allows you to
manage the passwords and the locked/unlocked status of accounts in the upgraded database.
