ORA-02080: database link is in use Problem

Dear experts,

I'm running a PL/SQL procedure to insert some values to a table in another database using DBLINK. My PL/SQL procedure uses Commit and then Alter Session Close Database Link commands. However, sometimes I got  ORA-02080 errors. The database link being used is not used by any other process I know. One more thing, the database link mentioned is based on Oracle Gateway to Sybase. In other words, other database is actually "Sybase".

Could you please help me.

Maybe you have other links open you don't know about or some other branch of your code is reopening links.

you can query v$dblink to find db links in use.  If you have ended your transactions you can iterate though them all and close them with a block like this...  (or use execute immediate with alter session, same effect)

    for l in (select db_link from v$dblink)
    end loop;

you can extend the above logic by checking the IN_TRANSACTION column and issuing a commit or rollback as needed before closing the link

The database user is not DBA, could it run "select db_link from v$dblink"?
by default, probably not.  

however I don't think there is anything public to check for open links in your own session.
