Goldengate Implementing Oracle for Oracle One-way DDL operation synchronization

In the http://lqding.blog.51cto.com/9123978/1695162 article we implemented the DML operation synchronization of the table.

We do the following tests

Truncate on the source side of the execution table

sql> truncate TABLE Tcustmer; Table truncated.

On the destination, view the table data

Sql> Select COUNT (*) from Tcustmer; COUNT (*)----------2

Data is not synchronized

How do we get goldengate to synchronize DDL operations?

To support DDL synchronization, you need to make some settings on the source database so that DDL operations can be traced. Includes the following trigger, marker, and history table, a user role, and a variety of other database objects.

1. First configure the Globals parameter to tell GG to use that schema to store DDL operations.
   

Ggsci (localhost.localdomain) 19> edit params./globals--GoldenGate GLOBALS parameter File--ggschema ggddl

2. Create a GGDDL user with Sqlplus and install DDL support

Sql> conn/as sysdbaconnected.sql> Create user ggddl identified by GGDDL; User created. Sql> Grant Connect,resource to GGDDL; Grant succeeded.

Turn off the data Recycle Bin feature

After creating the role, it is not to give the role to the GGDDL user, but to give the role to the schema used by Extract,replicat.

We previously configured the system user

Sql> GRANT ggs_ggsuser_role to System; Grant succeeded.

Enabling DDL is actually making trigger enable

Sql> @ddl_enable. Sqltrigger altered.

The data is synchronized.
