Overview of the Upgrade Procedure for Non-Oracle Databases

The upgrade performs a minimal feature upgrade to deploy only the core Oracle GoldenGate functionality, without implementing any of the major new features. It ensures easy troubleshooting of any upgrade related issues that may occur after the upgrade. After upgrading the Oracle GoldenGate environment successfully, you can implement the new functionality.

If you are upgrading multiple Extract processes that operate in a consolidated configuration (many sources to one target), you must upgrade one Extract at a time. All Replicat installations must be upgraded at the same time. It is critical to ensure that all trails leading to all Replicat groups on all target systems are processed until empty.

Note:

The hash calculation used by the @RANGE function to partition data among Replicat processes has been changed. This change is transparent, and no re-partitioning of rows in the parameter files is required. To ensure data continuity, ensure that you allow all Replicat processes on all systems to finish processing all the data in their trails before stopping those processes. If the Replicat processes are not upgraded all at the same time, or the trails are not cleaned out prior to the upgrade, rows may shift partitions as a result of the new hash method, which may result in collision errors.
