<br>
Thanks for your help, Karl. There should not be any rules on the<br>
table but I've no idea how to check. This is all getting way beyond<br>
my knowledge. Anyway I've looked at articles about enabling SC930<br>
tracing but I don't see any output since I made the changes.<br>
<br>
We have the II_SC930_LOC environment variable set to a valid directory<br>
and I have added "SET TRACE POINT SC930 1" to the code, but no files<br>
appear in the II_SC930_LOC directory and stdout has the following:<br>
<br>
"trace directory has not been set or is invalid, tracing will not be<br>
enabled.<br>
Please enter 'SET TRACE RECORD <logdir>' or set II_SC930_LOC and<br>
re-try."<br>
<br>
I will try to get some help from Ingres themselves, if possible!<br>
