C Connecting Oracle GoldenGate Classic Architecture to Microservices Architecture

Oracle GoldenGate Classic Architecture uses the data pump Extract in GGSCI to connect to Microservices Architecture.

Follow these steps for establishing a connection betweenOracle GoldenGate Microservices Architecture and Classic Architecture:

Create a data pump Extract

Note:

To perform this task, an existing data pump Extract must be running in Classic Architecture.

  1. Log in to GGSCI.

  2. Add a data pump Extract using the command:

    ADD EXTRACT dp_name, EXTTRAILSOURCE ./dirdat/aa

    This example uses, dp_name as the name of the data pump Extract.

  3. Add the remote trail to the data pump Extract using the command:

    ADD RMTTRAIL ab, EXTRACT dp_name, MEGABYTES 500

  4. Edit the parameter file for the data pump Extract using the command:

    EDIT PARAMS dp_name

    Here’s an example of the data pump Extract parameter file:

    EXTRACT dp_name
RMTHOST hostname/IP address, PORT receiver service port
RMTTRAIL ab
PASSTHRU
TABLE pdb.schema.table;
Start the data pump Extract

Use the following command to start the data pump Extract dp_name:

START EXTRACT dp_name

Once the data pump Extract has started, the Receiver Server establishes a path and begins reading the remote trail file. The remote trail file appears in the $OGG_VAR_HOME/lib/data of the associated deployment running the Receiver Server.
