Forgive me if this is a RTFM question - I have not been able to find the
right bit of the FM.

Can someone please tell me how to Net8 connect an 8.0 NT client to an 8.1
Linux server.

Everything was working fine until a second Oracle instance was installed on
the server.  I now get 

ERROR:
ORA-12545: Connect failed because target host or object does not exist


My tnsnames.ora looks like this...

ORANGE.WORLD =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 123.456.798.101)(PORT = 1521))
    (CONNECT_DATA = (SID = ORANGE))
  )

The server listener.ora looks like this

# LISTENER.ORA Network Configuration File:
/opt/oracle/product/8.1.7/network/admin/listener.ora
# Generated by Oracle configuration tools.

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
      )
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = TCP)(HOST = abc123defghi)(PORT = 1521))
      )
    )
    (DESCRIPTION =
      (PROTOCOL_STACK =
        (PRESENTATION = GIOP)
        (SESSION = RAW)
      )
      (ADDRESS = (PROTOCOL = TCP)(HOST = abc123defghi)(PORT = 2481))
    )
  )

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /opt/oracle/product/8.1.7)
      (PROGRAM = extproc)
    )
    (SID_DESC =
      (GLOBAL_DBNAME = TEST.abc123de)
      (ORACLE_HOME = /opt/oracle/product/8.1.7)
      (SID_NAME = TEST)
    )
    (SID_DESC =
      (GLOBAL_DBNAME = ORANGE.acn032hq)
      (ORACLE_HOME = /opt/oracle/product/8.1.7)
      (SID_NAME = ORANGE)
    )
  )

I anonymised the data (obviously)

Many thanks to anyone who understands this stuff.
