We have decision tables with over 12,000 rows. It is a basic ‘look-up’ table with 3 conditions and 2 actions. The conditions are, for example: Company = X Dept = X Class = X then value = X and log X. When I reduced the number of rows to approx. 500 . .. it works.<o:p></o:p></p><p class=MsoNormal>I have set the max memory in the JVM to 2 gigs. We have tried compiling the decision tables using the spreadsheet compiler as well as the decision table compiler.<o:p></o:p></p><p class=MsoNormal>Below is the error when using the decision table compiler. However, we get the same PermGen space error with the spreadsheet compiler.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Obviously, we need to be able to have more than 500 rows in our decision table(s). Any advice would be appreciated.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:Consolas;color:red'>Aug 14, 2014 6:33:09 PM
