Oracle Communications Services Gatekeeper(OCSG) is designed to achieve “five nines” (99.999%) service availability for a fully redundant deployment. Please refer this document about how the Services Gatekeeper design implements that level.


OCSG's high-availability mechanisms are supported by the clustering mechanisms made available by Oracle WebLogic Server. For general information about Oracle WebLogic Server and clustering, see Oracle Fusion Middleware Using Clusters for Oracle WebLogic Server here.
