Connection to an external database.

Question

Hi we r using native sql commands and are connecting to external database. As far as I know from the discussions here i thought that these sort of connections are maintained in the table dbcon. But i don't see any entries in that table.
WHere as i could connect to that database succesfully and getting the records.
The table name for the external system is NOVARTIS.TABLE_ADDRESS@ANK like this.
Where could be that settings made.

Try this Forum Thread:-
1. In developer server you have to configure the tnsnames.ora. For doing this you should talk with a person who knows how to configure this file. In the register you should especify: protocol, host and port to connect to the other database system.
2. Then, you enter a register in the DBCON table. In this entrie you especify user, password, database id (in my case I wrote ORA because i am connecting to an oracle database), and in the enviroment field you write the name or alias of the register in the tnsnames.ora
3. In the abap program you use native sql sentences for connecting to the external database. This is an example:
EXEC SQL.
CONNECT TO :p_conexion AS 'C1'
ENDEXEC.
IF SY-SUBRC EQ 0.
EXEC SQL.
SET CONNECTION 'C1'
ENDEXEC.
EXEC SQL PERFORMING save_data.
SELECT COD_CGE, COD_SAX, TO_CHAR(FECHA,'YYYYMMDD'),
VALOR, HORA, TIPO, PAIS, SOCIEDAD
INTO :wa_serv_aux
FROM TEST_TABLE
WHERE FECHA >= TO_DATE( :W_FEC1 , 'YYYY/MM/DD')
AND FECHA <= TO_DATE( :W_FEC2 , 'YYYY/MM/DD')
ENDEXEC.
EXEC SQL.
ROLLBACK
ENDEXEC.
EXEC SQL.
DISCONNECT 'C1'
ENDEXEC.
In the form save_data i insert the work area into the internal table.
And that`s all. The most important thing is to configurate the tnsnames.ora file on the server side.
