Connect to Oracle AI Database
Learn how to create a connection to an Oracle AI Database to use as a source or target.
Before you begin
Ensure that you:
- Review how OCI GoldenGate connects to your sources and targets.
- Depending on your Oracle GoldenGate version:
- For Autonomous AI Database, Unlock the GGADMIN user.
- Configure the required policies to enable secure Vault and Secrets access, such as use secrets, use vaults, and read secret-bundles. For more information, see Minimum recommended policies.
Create the connection
To create an Oracle AI Database connection:
After the connection is created, it appears in the Connections list. Ensure
that you assign the connection to a deployment to use it as a source or
target in a replication.
Known issues with Oracle AI Database connections
Network timeouts affect database connections using private endpoints
If you're using a private endpoint to connect to a database, then you may encounter network timeouts when starting or stopping Extract processes.
Workaround: You can do one of the following:
- Apply the latest patches from your deployment details page. In the Deployment Information section, under GoldenGate, for Version, click Upgrade.
- If you're unable to apply the latest patches at this time, you can
update the connection string to include
EXPIRE_TIME=1. By default, you may have an EZ connection string in Oracle GoldenGate. This connection string needs to be updated in the Oracle GoldenGate Credential to a long connection string as follows:<username>@//<hostname>:1521/<service_name> <username> @(DESCRIPTION = (EXPIRE_TIME=1)(ADDRESS_LIST = (ADDRESS = (COMMUNITY = tcp)(PROTOCOL = TCP)(Host = <hostname>)(Port = 1521))) (CONNECT_DATA = (SERVICE_NAME = <service_name>)))
Redirect session mode with SCAN listener connection doesn't support TCPS and TLS
OCI GoldenGate doesn't support connections that use Redirect session mode with Oracle Single Client Access Name (SCAN) using TCPS and TLS. TCP is supported.
Workaround: Configure a connection using the Direct session mode to an individual Real Application Cluster (RAC) node.
