The Database Link is not active
Two database links were imported into a schema. I tested one of the dblink by describing one of the remote table (i.e. desc <schema>.<table>@<dblink>) successfully. But, when I test the same dblink from the EM Console by pressing the test button, I got the following error:
The Database Link is not active.
ORA-02019: connection description for remote database not found
Could someone explain why the error occurs? By the way, both dblinks are valid objects.
I did a query on user_db_links and saw no passwords listed. Are the passwords supposed to be encrypted?
