AutoUpgrade 21c Release: New Features/Enhancements

Belong to Below environment:

Oracle Database – Enterprise Edition – Version 12.2.0.1 and later
Oracle Database – Standard Edition – Version 12.2.0.1 and later

Overview:

Oracle Database AutoUpgrade allows DBAs to upgrade one or many databases without human intervention, all with one command and a single configuration file.

Advantages:

AutoUpgrade enables customers to upgrade one or many Oracle databases at the command-line with a single command and a single configuration file. AutoUpgrade will run the preupgrade tasks, perform automated fixups where needed, execute the database upgrade, and finish by taking care of post-upgrade tasks. It includes automatic retry and fallback, the possibility to schedule upgrades for future points in time, and the ability to set, change or remove initialization parameters as desired. It saves time and money by upgrading hundreds of databases with one command and replacing bespoke high maintenance upgrade solutions.

How to Install

As of the January 2019 Release Updates (DBJAN2019RU) and beyond, AutoUpgrade Support is available for Oracle Database 12c Release 2 (12.2) and Oracle Database 18c (18.5) target homes. For both Oracle Database 12c Release 2 (12.2) and Oracle Database 18c (18.5) target homes, you must download the AutoUpgrade Tool and place it under $ORACLE_HOME/rdbms/admin.

In Oracle Database 19c (19.3) and later target Oracle homes, the autoupgrade.jar file exists by default. However, before you use AutoUpgrade, Oracle recommends that you download the latest version and replace the one already existing under $ORACLE_HOME/rdbms/admin.

• Database restoration option is not available on an Oracle Database Standard Edition.

AutoUpgrade 21c Release: New Features/Enhancements

• Non-CDB to PDB Upgrades

  • Support for RAC and SI databases
• Unplug-plug upgrade
  • AutoUpgrade can perform an unplug of a pluggable database (PDB) from an earlier release source container database (CDB), plug it into a later release target CDB, and then complete all the steps required to upgrade the PDB to the target CDB release
• Supports RAC upgrades (Only for Linux or Unix-based systems)
  • Configuration of the RAC management system in the source and target home is automated
  • Supports native file systems, ASM and ACFS
  • Oracle Restart
  • Pluggable databases are supported in a RAC environment
• Ability to pass catctl_options (via config file)
  • This enables the DBA to control the level of parallelism for a specific upgrade.

  • AutoUpgrade restore job option allows the DBA to restore database back to source home if upgrade failed or succeeded
• Clear the recovery for a specific job by adding clear_recovery_data on the command line and use jobs parameter to specific exactly which jobs recovery data must be cleared.
• Upgrades on Data Guard environments
  • AutoUpgrade can detect Oracle Data Guard configurations, and defer shipping logs to standby databases configured for the primary database. It will also detect and defer shipping logs to standby database if the deployment is configured manually. Upon a successfully upgrade of the primary database, upgrades to the standby database must be performed and monitored by the DBA.

    • analyze: Check your system for readiness to upgrade
    • fixups: Perform fixups as needed on your source Oracle Database release in preparation for upgrade
    • postfixups: Perform fixups on your target Oracle Database release after upgrade is completed.
    • Reports are identical to what the preupgrade.jar originally produced.
• Starting Oracle Release 21c, Enterprise Manager, DBUA and ORAchk use AutoUpgrade to perform database upgrade readiness.
• Starting Oracle Release 21c, FPP performs database upgrades using AutoUpgrade
• Enhanced management of databases using Transparent Data Encryption (TDE)
