Some Tips & Tricks for JCS

Based on our experience and customer feedback, here you can find some Tips & Tricks for Oracle Java Cloud Service:

To ensure that you can restore the database for an Oracle Java Cloud Service instance without risking data loss for other service instances, do not use the same Oracle Database Cloud - Database as a Service instance with multiple Oracle Java Cloud Service instances. Backups of an Oracle Database Cloud - Database as a Service instance that is used with multiple Oracle Java Cloud Service instances contain data for all the Oracle Java Cloud Service instances. If you restore the database while restoring an Oracle Java Cloud Service instance, data for all the Oracle Java Cloud Service instances is restored. Apply only patches that are available through Oracle Java Cloud Service. Do not apply patches from any other source. You can get the list of available patches for a service instance from the service instance's Patching page or through the Oracle Java Cloud Service REST API. Use only the default domain that was provisioned when a service instance was created. Do not add any Oracle WebLogic Server domains to the service instance. If you plan to integrate multi-domain environments, ensure that the first eight characters of your Oracle Java Cloud Service instance name are unique so that all domains and associated resources have unique names. For more information, clickhere for Oracle WebLogic Server 12.1.3.0 andhere for Oracle WebLogic Server 11.1.1.7. Add managed servers to a service instance only by scaling out the Oracle WebLogic Server cluster in the service instance. Do not use Oracle WebLogic Server administrative interfaces for this purpose. For information about how to scale out the cluster in a service instance, seehere. When Oracle Coherence is enabled for a service instance: The Coherence data tier is scaled independently of the application tier. Seehere for information about scaling out the Coherence data tier by adding a capacity unit. Add Oracle WebLogic Server clusters to a service instance only by using the Oracle Java Cloud Service REST API for scaling out a service instance. Do not use Oracle WebLogic Server administrative interfaces for this purpose. For information about the REST API for scaling out a service instance, seehere. When Oracle Coherence is enabled for a service instance: Note that you can scale out the Coherence data tier but you cannot add a second data tier WebLogic Server (storage-enabled) cluster in the domain. Seehere for information about scaling out the Coherence data tier. When Oracle Coherence is enabled for a service instance: Use only the DataGridConfigCoherence cluster that was created when the service instance was initially provisioned. Do not use defaultCoherenceCluster.
