Sorry for the delay in replying; something more urgent popped up.



Nope, the x$uganco doesn't show the db_links opened by other sessions.
The inst_id field looks like it would be useful only in Parallel Server
environments. Any other ideas?



I can't believe Oracle doesn't keep track of open database links. There
must be some x$ view for this. How to find it out?



Thanks & regards,


Charu.

There is an underlying x$table named x$uganco that contains a column
named inst_id which is being filtered in the view_definition for
V$DBLINK as found in V$FIXED_VIEW_DEFINITION.  Selecting from the
x$uganco should do the trick.  Mind you there are no rows in there when
the links are not active so this may be a real problem for you in terms
of capturing all the links.

I think I spoke too soon.



The v$dblink view shows the db_links opened by the current session only.



I want to be able to find out the db_links opened by all current
sessions and the sids for the sessions. This way I can monitor all the
application instances that opened the db_link and those that didn't
close it.



Thanks & regards,


Charu.

Darn!!



I had taken a hasty look at 'Oracle 8i reference', before posting the
query. Not my day today.



Thanks Allan.



Regards,



Charu

Dear Listers,



Oracle 8i HP-UX11.



We have a database link with a remote database which is accessed from
the application code. In the application code, a call is made to the
'dbms_session.close_database_link' procedure (that is what they
claim!!).



We want to track the call to the database link and the subsequent
closure. We don't have any access to the remote system to check the
remote session being created and closed.



Is there any way (dynamic performance view etc.) which would show the
database link being in use and closed again on the local database
itself?



Thanks & regards,


Charu
