I am trying to create a database troy2 using dbca – silent mode. there is already a database named troy running on this serever

new db - troy2
existing db - troy
server - oel6-node01.eu.brit 
listener - configured with floating ip remote.eu.brit / 1521

I recieved this error message

ORA-29532: Java call terminated by uncaught Java exception: java.net.BindException: Unable to bind endpoint, status = 12541<0.0.0.0,2482>

In my case i was creating database on HP-UX box which has service guard package floating IP assigned in the listener.ora

remote.eu.brit – service guard package floating IP

oel6-node01.eu.brit – my actual host 

 cat listener.ora

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = TCP)(HOST = remote.eu.brit)(PORT = 1521))
      )
    )
  )

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = troy.eu.brit)
      (ORACLE_HOME = /u01/infra/oracle/product/infra)
      (SID_NAME = troy)
    )
  )

as there were other databases running on this server using this default listener so i added one more listener with host=localhost.

note that you have to use port 1521 and localhost in the new listener. instead of locahost you can try oel6-node01.eu.brit as well. If there was already a default listener with host=oel6-node01.eu.brit and port 1521 then you might not receiev this error message.

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = TCP)(HOST = remote.eu.brit)(PORT = 1521))
      )
    )
  )

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = troy.eu.brit)
      (ORACLE_HOME = /u01/infra/oracle/product/infra)
      (SID_NAME = troy)
    )
  )


LISTENER_troy2 =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
     (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
     )
    )
  )

SID_LIST_LISTENER_troy2 =
  (SID_LIST =
    (SID_DESC =
        (GLOBAL_DBNAME = troy2.eu.brit)
        (ORACLE_HOME = /u01/infra/oracle/product/infra)
        (SID_NAME = troy2)
      )
    )

start the listener LISTENER_troy2 and try again dbca. it should succeed now.
