About Oracle Database AutoUpgrade
The AutoUpgrade utility is designed to automate the upgrade process, both before starting upgrades, during upgrade deployments, and during postupgrade checks and configuration migration
When you perform upgrades, Oracle
recommends that you download the most recent version of the
AutoUpgrade utility (autoupgrade.jar) to prepare
for and to deploy your upgrade. You use AutoUpgrade after you have
downloaded binaries for the new Oracle Database release, and set up
new release Oracle homes. When you use AutoUpgrade, you can upgrade
multiple Oracle Database deployments at the same time, using a
single configuration file, customized as needed for each database
deployment. You can now download the latest AutoUpgrade utility
release directly from the Database Upgrades and
Migrations page without having to log in to My Oracle
Support: Download the AutoUpgrade
utility
The autoupgrade.jar file exists by default in the Oracle home
(Oracle_home/rdbms/admin).
However, before you use AutoUpgrade, Oracle strongly recommends that you download the
latest AutoUpgrade version. AutoUpgrade is included with each release update (RU), but
the most recent AutoUpgrade version is always available from the Database Upgrades and
Migrations page.
Note:
AutoUpgrade is available for Oracle Database Enterprise Edition, and Oracle Database Standard Edition. It is not available for other Oracle Database editions.
Preventing Issues: Analyze and Fixup Modes
Before the upgrade, in Analyze mode, the AutoUpgrade utility performs read-only analysis of databases before upgrade, so that it can identify issues that require fixing. You can run the utility during normal database operations. In Fixup Mode, the AutoUpgrade utility detects and identifies both fixes that require manual intervention, and fixes that the AutoUpgrade utility can perform during the upgrade deployment phase.
Simplifying Upgrades: Deploy and Upgrade Modes
In Deploy phase, the AutoUpgrade utility modifies the databases you indicate in your configuration file. It enables you to call your own custom scripts during the upgrade to configure databases. In many cases, the AutoUpgrade utility can perform automatic fixes to databases during the upgrade process without requiring manual intervention.
Deploy and Upgrade Postupgrade Checks and Fixes
After an upgrade completes with either Deploy or Upgrade modes, AutoUpgrade performs
postupgrade checks. It provides a process where you can enable your custom scripts
to be run on each of the upgraded databases, in accordance with the configuration
instructions you provide in the AutoUpgrade configuration file, and also can run
automatic postupgrade fixups as part of the postupgrade process. In Deploy mode,
AutoUpgrade also confirms that the upgrade has succeeded, and copies database files
such as sqlnet.ora, tnsname.ora, and
listener.ora from the source home to the target home. After
these actions are complete, the upgraded Oracle Database release is started in the
new Oracle home.
