Bug 33096609

Users who have enabled Oracle Sharding and are using Oracle Native Encryption to communicate between the shard catalog and the shards should be aware that sharding uses database links to communicate from the catalog database to the shards, and also enables shared servers (dispatcher) on the catalog database. This combination of settings is currently an issue and some sharding features such as cross-shard queries fail.

Workaround:

In Oracle Database Release 19c or later, it is no longer necessary to enable shared servers on the catalog database and we recommend that, if you are using Oracle Native Encryption with sharding, you should disable shared servers on the catalog database. This can be done by setting the database parameter shared_servers to 0 and restarting Oracle. This is a global parameter that must be set in the multitenant container database.

Bug 33090781

If the Oracle Database user password has expired, then you might not be able to use the password command to change the password if the network encryption is enabled.

Workaround:

Contact your database administrator to change or reset the password.
