How to Define PDB Listeners With Different Ports In A Multitenant Setup Goal

 This Note will discuss the necessary steps to create and configure listeners for a Pluggable Database (PDB) in a Multitenant environment.

Solution

 1. Using netca create a 2nd listener on a unique port
     This creates a listener.ora file in the ?/network/admin directory similar to: 

PDB_LISTENER =
   (DESCRIPTION_LIST =
     (DESCRIPTION =
       (ADDRESS = (PROTOCOL = IPC)(KEY = test))
       (ADDRESS = (PROTOCOL = TCP)(HOST = host.us.oracle.com)(PORT = 1524))
       (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1524))
     )
   )

 ENABLE_GLOBAL_DYNAMIC_ENDPOINT_PDB_LISTENER=ON          # line added by Agent
 VALID_NODE_CHECKING_REGISTRATION_PDB_LISTENER=SUBNET           # line added by Agent

  



 2. Within the PDB issue the following statement:  


alter system set listener_networks='(( NAME=net1)(LOCAL_LISTENER=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=host.us.oracle.com)(PORT=1524)))))' scope=spfile;

  Remarks:
     - use scope=memory for testing only
     - LOCAL_LISTENER and REMOTE_LISTENER parameters are not PDB modifiable.

3. modify the PDB service definition in tnsnames.ora to point to the correct port
  


PDB1 =
   (DESCRIPTION =
     (ADDRESS = (PROTOCOL = TCP)(HOST = host.us.oracle.com)(PORT = 1524))
     (CONNECT_DATA =
       (SERVER = DEDICATED)
       (SERVICE_NAME = pdb1)
     )
   )

  

4. The LREG process will automatically register the service with the listener after executing the command from section 2.

 Connections and lsnrctl service/status pdb_listener output are all correct for the connection.
