12c: PDB Listener Configuration for Different Timezone (Unix only)
It is possible to configure a listener so that a PDB uses a different ENV than the CDB.
See the following document:
12c: How to Configure ENVS for Different Timezones for PDBs (Doc ID 2183101.1)
It is advisable to use a listener.ora configuration that is separate from the listener configuration where the CDB
and any other PDBs are dynamically registered. The document calls for the USE_SID_AS_SERVICE_listenername=ON
setting which can impact the connections to the dynamically registered services.
