Hi Mikael ,
We use Cloverleaf 5.4 Rev 1 with WinXP for the client and Aix 5.2 (Unix) for the server and using Oratcl and it’s working great. But you willl need to do a specific setup to use Oratcl. I can send you and example of TCL proc if you contact me directly to my email address : gaetan.michaud.chum@ssss.gouv.qc.ca
That proc read and update in Oracle database.
Bye
Ga
