Hi Sebastien, > Oracle 8.1.5 with a jdbc2 driver from 9i ? We have been running opencms 5.0RC2 on Oracle 8.1.6 for quite a long time now w/o any problems. We used Oracle-Thin in classes12.zip and GENERICSQL-settings of opencms. I think, that´s unfortunately only "any hint", but maybe it helps. Best regards, Kai
