Connection to external database

Question

Hi All,
we have an requirement to connect SAP R/3 to external database which is oracle and java tool for data uploading.
One of our team abaper requested us to establish the connection.
When explored , i got some info on DB11 and DBCON table.
I created the connection with the DBM user control and SAP user SAPR3.
Please let me know how to test the connection further and details on connection to external database from BASIS point of view.
Thanks

Hi,
Using transaction SE11, create a table (ZTABLE) with the same fields as the table in the external database, make sure that the type and lengths of the fields are identical.
Using transaction SE11, create a view (ZTABLE_VIEW, projection view) using BASIS table ZTABLE
Using SVRMGRL>
create dblink REMOTE_DB as connect to remote_user identified by password; (database link created)
drop table ZTABLE; (table dropped)
create synonym ZTABLE for ZTABLE@REMOTE_DB; (synonym created)
Using transaction SE16 , type in ZTABLE_VIEW and hit RETURN
Enter value in key fields and hit execute. (displays rows from the remote table)
In other words
To access an external database from ABAP via DBLINK (ORACLE)
Using transaction SE11, create a table (ZTABLE) with the same fields as the table in the external
database, make sure that the type and lengths of the fields are identical.
Using transaction SE11, create a view (ZTABLE_VIEW, projection view) using BASIS table ZTABLE
Using SVRMGRL>
create dblink REMOTE_DB as connect to remote_user identified by password; (database link created)
drop table ZTABLE; (table dropped)
create synonym ZTABLE for ZTABLE@REMOTE_DB; (synonym created)
Using transaction SE16 , type in ZTABLE_VIEW and hit RETURN
Enter  value in key fields and hit execute. (displays rows from the remote table)
