DDL Replication Configuration of Oracle GoldenGate 11g
We have already seen in my previous post How to install Oracle GoldenGate 11g and configure DML in it. In this post, let us continue with the same set up by configuring the DDL replication with Oracle GoldenGate 11g.
The Details are given below.,

Let us continue from the Previous post. Now is the Step 5. Request to follow the below to configure the DDL Replication.

CHANGES NEED IN EXTRACT
There are certain parameters to be added to the EXTRACT Process. Adding these parameters to the EXTRACT Process starts / enables DDL Operations in GoldenGate.
Login to the ggsci prompt and make the necessary modifications.

TO PERFORM DDL OPERATION
CHANGES IN REPLICAT – Similar to the EXTRACT Process, REPLICAT process also required some changes (some parameters to be added for DDL Operations).
Now Login to the GGSCI prompt.,

DDL INLCUDE MAPPED / ALL – All types of DDL operations are enabled for all objects.
For egs., we can enable only “create” or “alter” separately.
DDLOPTIONS REPORT – Creates and Manages REPORTS. When issuing VEIW REPORT <Group_Name> we can see the complete report of the DDL operations taken place.
DDLERROR DEFAULT IGNORE RETRYOP – When an error occurs in the DDL Operation, GoldenGate just IGNOREs it and retries the Operation. We can set the retry options in numbers like 3,4 and interval time in seconds.
GoldenGate process retries the operation for 3 times in a particular interval of time. If the operation is still not cleared the respective process will ABEND.

Now you can check if the DDL Replication is happening or not. Perform some DDL operations like create table, alter table etc in source and check if it is replicating it to the secondary database.
Hope you understood clearly on configuring the DDL Replication using Oracle GoldenGate between two databases.
