I have overcome the connection description for remote database not found error but now get the following error : Looks like a privilage thing, but I do not understand this. Since I am able to run dbms_aqadm commands under my user on both databases surely the privileges are OK?

Why is it trying to use VAN9.US.ORACLE.COM ??? The entry in tnsnames.ora is simply named VAN9. From: John Dunn [mailto:jdunn@xxxxxxxxx] Sent: 17 February 2005 10:46 To: 'Oracle-L@xxxxxxxxxxxxx' Subject: Advanced queuing : dequeing from remote database I am experimenting with advanced queueing in Oracle 9i and am able to enqueue and dequeue messages within the same database. However I would like to dequeue messages on a remote database via a database link. I am confused as to what I need to set up on the remote server in order to dequeue the message. I have set up the database link that points back to the enqueueing database, The database link works OK. I am then trying to dequeue the message on the remote database using the following code(which is the same I use when doing this all on the same database except for the references to the database link). I get the error : message opd4678.new_job_message@DEMO; * ERROR at line 6: ORA-06550: line 6, column 34: PLS-00331: illegal reference to OPD4678.NEW_JOB_MESSAGE@DEMO Any ideas what I have done wrong?
