Oracle Golden Gate on Exadata | Configure OGG

In the previous article  Install OGG, we noticed that the installation of the software Oracle GoldenGate finished fine and could observe that the manager runs fine.

So, We need to start with the following steps to continue with the awaited moment, replication.

Also for easy administration and execution of the OGG command line, it recommends setting the environment variables.

Usually, I set the env variables to avoid issues.

export OGG_HOME=/ggate/OGG/11.2.0/<$ORACLE_SID>
export ORACLE_HOME=/u01/app/dbhome/

You can set it, on the .bash_profile or (I preferred using a simple env variable script on the user home) an script.

The config used in the previous step, avoid some error that will appear, for example:

./ggsci: error while loading shared libraries: cannot open shared object file

Keep in mind this check:

  • tnsnames
  • Define TNS_ADMIN
  • Create sub dirs [OGG_CONSOLE]
  • Prepare the Source Database
  • Configure Parameters on Source and Target Databases for Golden Gate.
  • Configure Users on Source and Target Databases.

Let’s start!

mv /ggate/OGG/STAGE
cd /ggate/OGG/STAGE
  • Set the X variables and execute the OGG installation.
cd fbo_ggs_Linux_x64_shiphome

Oracle Golden Gate on Exadata | Configuring ACFS

Good Morning Guys! I am starting a new challenge, and my articles will be written in English Mode, because the best part of the public and messages that I receive every day are from India, England, the USA and many countries around the world.

I love the Community and promise to continue giving support and answers to a lot of mails in Spanish that I receive every week. Let’s start!

Matrix Installation

Product Version
Oracle Golden Gate
Exadata Image Version
Oracle Grid Infrastructure

Pre Requisites

We’ll start with a summary of tasks that we need to keep in mind to start with the configuration and installation of Oracle Golden Gate on a RAC environment. It’s necessary :

  • As a share file system, we chose ACFS (ASM Cluster File System) under grid infrastructure 12.1.0
  • Oracle Golden Gate.

Creating and configuring ACFS on Exadata

When we working on an Oracle RAC environment, we must install an OGG on a cluster file system. As part of the architecture design, we choose the ACFS, but we could use NFS or DBFS.

My decision was based on my experience with this FS and listening to the council from others partners, that was used on ODA implementations.

Basically, my procedure is same that on Non-Exadata Environments:

. oraenv

On the next screen, we can see the name of the candidate DG.

Generally, we find typically three disk groups.

  • We choose the DBFS_DG .
