In 19c or higher, it is no longer necessary to enable ‘Shared Servers’ on the catalog database, so Oracle recommends that (if you are using Oracle Native Encryption with sharding) you disable Shared Servers on the catalog database. This can be done by setting the database parameter shared_servers to “0” and restarting Oracle. Note that this is a global parameter set in the Container Database.

Oracle Sharding on Oracle Container Engine for Kubernetes (OKE) uses StatefulSet to provide stable, unique network identifiers and stable, persistent storage so you can create and manage your Oracle Sharding replica set natively in OKE with Oracle supported helm and chart templates. In addition, data is stored on persistent volume, so all the data is still there when a pod is recreated.
