19c RMAN-04006: error from auxiliary database: ORA-12514: TNS:listener does not currently know of service requested in connect descriptor

 19c RMAN-04006: error from auxiliary database: ORA-12514: TNS:listener does not currently know of service requested in connect descriptor


Before doing an RMAN DUPLICATE DATABASE from an Active Database, we need to set up listener on the target environment with static registration.  Else when the RMAN shuts down the auxiliary database for creating spfile or making changes in it, it will not be able to connect the auxiliary and start the database (nomount) and throw the error :


RMAN-04006: error from auxiliary database: ORA-12514: TNS:listener does not currently know of service requested in connect descriptor


To Solve this issue ensure that listener is configured with static registration using the below syntax :

========= LISTENER.ORA==================

EBSUPG=

  (DESCRIPTION_LIST =

    (DESCRIPTION =

      (ADDRESS = (PROTOCOL = TCP)(HOST =<hostname>)(PORT = 1536))

      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1536))

    )

  )



SID_LIST_EBSUPG=

  (SID_LIST =

    (SID_DESC =

      (GLOBAL_DBNAME = EBSUPG)

      (ORACLE_HOME = /u01/app/oracle/product/19.0.0/dbhome_1)

      (SID_NAME = EBSUPG)

    )

  )


ADR_BASE_LISTENER_EBSUPG = /u01/app/oracle

=================================================================

When we check the listener status, it should show as UNKNOWN instead of BLOCKED 

-bash-4.4$ lsnrctl status EBSUPG

This solved my issue and it started with the ACTIVE DUPLICATE.
