This topic describes the following discovery-related errors:

• Authentication Issue
  
• Connection Issue
  

11.2.2.1.1 Authentication Issue

Ensure that you are able to login to the Oracle GoldenGate Microservices URL using the correct credentials that you have entered in the Oracle GoldenGate Enterprise Manager Plug-in to successfully discover Oracle GoldenGate Microservices targets.

11.2.2.1.2 Connection Issue

If discovery is not successful and a Connection Exception has occurred, then you need to ensure the following:

• The Oracle GoldenGate Service Manager is up and running in case of Oracle Cloud Infrastructure (OCI) Marketplace instances or on-premises GoldenGate instances.
• Ensure that the Administration Service and Performance Metrics Service are up and running.
• There is no firewall blocking connection to the Oracle GoldenGate host from the Enterprise Manager Agent host.
• Oracle GoldenGate REST APIs (Performance Metrics Service) are accessible from the Enterprise Manager Agent. For example, use the cURL command to test the connectivity to the Oracle GoldenGate REST APIs. For more information about using the command, see REST API for Oracle GoldenGate.
• If Oracle GoldenGate is running with SSL, then you need to import the certificate at the Enterprise Manager Agent TrustStore. Ensure that the certificate is imported in the correct Enterprise Manager agent that monitors the corresponding GoldenGate targets. You can view and download the certificate using the browser by logging into the Oracle GoldenGate Administration Service UI or the Service Manager UI in case of OCI GoldenGate instance.
