In this note we will cover how to install and configure Oracle Goldengate 19c Microservices on an Oracle 19c RAC environment.
We will then configure high availability for GoldenGate Microservices using Grid Infrastructure Agent XAG v10.
Finally we will test the high availability by simulating a RAC node failure and verify that the GoldenGate Microservices Service Manager process has failed over automatically to the surviving node in the RAC cluster.
Create the ACFS file system using the ASM disk group ACFS
Create the directories to install GoldenGate 19c Microservices, Service Manager and the Deployment home
