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.
