does it reproduce in sql*plus? 
 
ORA-3113 quite often means call Oracle support.
 
>From asktom.oracle.com:
 
The underlying cause of a 3113 can be diagnosed typically by:

o inspecting the alert log on the server.  There should be a message in there 
typically that tells of the error occuring and gives the name of a trace file.

o the trace file will contain more details.  Most importantly, you can see the 
SQL statement that was executing usually at the time of the crash.  This can be 
useful in diagnosing the statement that is giving us a hard time.  The 
remainder 
of the trace file will not be very useful to you -- but it will be useful to 
support which is your next step....

o contact support with the contents of the trace file.  For errors like this, 
the information in the trace file can be used by support/development to track 
down the cause of this error.

Hi Jeffrey, thanks for your help. I have added those parameters, but 
unfortunately it doesn't seem to make a lot of difference. The errors are now 
just appearing earlier:

DBD::Oracle::st execute failed: ORA-03113: end-of-file on communication channel
(DBD ERROR: OCIStmtExecute) at ./query_db2.cgi line 30.
DBD::Oracle::st execute failed: ORA-03113: end-of-file on communication channel
(DBD ERROR: OCIStmtExecute) at ./query_db2.cgi line 30.

The SQL Statement I am running is:

select max(request_id) from [EMAIL PROTECTED]

I can select rows from tables in the current DB with no problem. It's just the 
link that seems to be letting me down.

Help!
Richard

That's a client side error meaning that you have been disconnected
without 
trapping the server side error.

Try setting RaiseError => 1 in your dbhandle and see if that gets the 
server side error.

$dbh = DBI->connect($dsn, $user, $password,
{ RaiseError => 1, AutoCommit => 0 });

Depending on how your code is structured, and what the real error is,
that 
may trap the error before you get disconnected.

Also look for differences between what you are doing in your script and 
what you are doing when you run the query in sql*plus such as different 
user, different client version, etc.... (You can run the query 
successfully in sql*plus, right?)

Hi guys,

I am trying to resolve a horrible error I am getting, and I really don't

know
where to start! I have created a Database link in Oracle and created a 
view
to one of the tables in it. Now when I run the SQL statement, I get:

ORA-03113: end-of-file on communication channel (DBD 
ERROR: OCIStmtExecute)

I really have no idea where to begin on this one.

Hope you can help
Richard
