The REST APIs for Oracle Clusterware enable you to remotely run commands on your cluster in the Oracle Cloud, at remote physical locations or locally provisioned. With the remote processing of REST interface commands, you can retrieve information about that processing, including output, error codes, and processing duration. In some cases, a command generates a file as output. In such cases, the REST interface also provides a Uniform Resource Identifier (URI) to retrieve the file. The REST interface provides secure support for Oracle Clusterware CLUVFY, CRSCTL, and SRVCTL command line interfaces (CLIs).
