Overview of the Upgrade Procedure

Learn about the prerequisites of performing an upgrade for Oracle GoldenGate Classic.

As a best practice, perform a minimal upgrade first, so that you can troubleshoot more easily in the event that any problems arise. Once you know your environment is upgraded successfully, you can implement the new functionality.

The upgrade instructions also take into consideration the steps to take if you are upgrading the source or target database at the same time that you are upgrading Oracle GoldenGate. Take into account the following pre-upgrade requirements:

• Only if the trail file format is being changed, allow the Oracle GoldenGate processes to finish processing all current DML and DDL data in the Oracle GoldenGate trails.

• (Oracle only) Disable the DDL trigger if there is no native DDL support. Integrated Extract in Oracle 11.2.0.4 and up does not require the DDL trigger.

• When upgrading your database and Oracle GoldenGate simultaneously, you must upgrade the database first.
