Upgrade Oracle Golden Gate 12cR1 to 12cR2

In this article, we will look at Oracle Golden Gate upgrade from 12.1 to 12.2 on a Linux server. Make sure you Allow golden gate processes to finish processing all current DML and DDL data in GG trail files.

If upgrading DB along with GG, upgrade DB first

Golden Gate Upgrade Prerequisite


Stop user activity on source objects which are involved in replication

Stop Extract

GGSCI> lag ext1
GGSCI> stop ext1

Make sure replicat applies all transactions on target

GGSCI> lag rep1

Stop pump and Replicat

GGSCI> stop dp1
GGSCI> stop rep1

Stop Manager on both source and target

GGSCI> stop mgr

Take backup of GG_HOME on both source and target


If you want to upgrade source and target DBs, this is the time. Once DBs are upgraded still, make sure there is no activity on source objects involved in the replication

Perform Golden Gate upgrade

  • Download the latest 12.2.0.2 Golden Gate and copy the zip file to both source and target DBs

  • Unzip and start the runInstaller

  • Give same old GG_HOME location while installation – Do not worry, this option will auto-upgrade old GG

  • Do not start manager

  • Perform installation on both source and target DBs in the same old GG_HOME location

Run @ulg script for supplemental log upgrade from GG_HOME

cd $GG_HOME
Sqlplus / as sysdba
SQL> @ulg.sql  press enter when prompted

Rollover Extract, Pump, and Replicat to next trail sequence number

On source DB:
=============
alter extract ext1 etrollover
alter extract dp1 etrollover
info ext1 detail
ALTER EXTRACT dp1, EXTSEQNO <above_seq_no>, EXTRBA 0
info dp1 detail

On target DB:
=============
alter replicat rep1, EXTSEQNO <above_seq_no>, EXTRBA 0

Start Manager, Extract, Pump, and Replicat

  • This is an oracle known error. You get prvtlmpg.plb script with GG binaries. This resides under $GG_HOME.

  • Run this script on both source and target database

cd $GG_HOME
Sqlplus / as sysdba
SQL> @prvtlmpg.plb

--> press enter when prompted

Allow activity on source objects involved in the replication.
