Check to see if you have any system triggers [eg a LOGON or LOGOFF trigger].
However, 4092 is an obvious "cannot COMMIT or ROLLBACK in a trigger "

People -
I have a puzzling situation here, and would be grateful for any
input.
We have two instances, geographically remote, both v8.1.7, and both
connected using Net8.
Database links are created differently on both instances - as thus:
On instance DB2:
create database link Ora1 connect to FRED
identified by xxxxxxx using 'DB1.WORLD ';
and on instance DB1:
create database link Ora2 connect to FRED
identified by xxxxxxxx using 'DB2 ';
DBlink 'Ora1 ' cannot be created using the form applied to the
creation of DBlink 'Ora2 '. The names are changed to protect the
innocent, and no, we are NOT using DB2... :-)
These links work, data can be queried, tables described etc.
However, if while connected to instance DB2, and one then retrieves
data from DB1 using the link, and then attempts to connect to DB1 as
thus: SQL >connect fred@(protected) - the following error appears:
If no use of the database link had been made during that session, a
connection to DB1 would have been entirely successful. Further, it
is not as though cause can be traced to a trigger on the remote
table being queried, as the error appears even after querying a
table with no triggers on it.
Can anyone advise on what we have overlooked here? I must admit
that I have not spent much time in the TNS area, so could have
overlooked something obvious. The text for the first error
message (0604) ends with the ominous 'contact customer support ' -
is it time to do this?
thanks,
peter
