Oracle Database Exadata Cloud Service (ExaCS) is one of the offerings in Oracle Database Cloud Service. With ExaCS, you can have databases running on high-performance Exadata box in the cloud with a full stack of integration including database-to-disk optimization and automation. ExaCS brings a level of performance previously unavailable to customers with Oracle database instances running in the public cloud.
GGCS supports capturing from and delivering to Exadata Cloud Service and Other Database Cloud services. The replication is based on the remote capture and delivery architecture. To enable Oracle GoldenGate replication, all the configuration is the same as the setup for Oracle Database Cloud Services except that you need to file an SR to whitelist the GGCS IP address so that GGGCS can communicate with the Exadata DB instance with the SQL*Net connection. The SR would typically include the following information:
- IdentityDomain ID -xxxxxx of the GGCS VM
- Source Compute instance - GGCS VM IP address
- Exadata CS SQL*Net Port: 1521
1. Oracle GoldenGate Cloud Service doesn't support Oracle database 12.2 capture yet.
2. With Exadata CS X6, you can complete the whitelist operation using the UI interface.
