Upgrade 10g to 11g publisher with error oracle.xdo.XDOException: java.lang.reflect.InvocationTargetE
I upgraded 10g publisher reports to 11g and I encountered error oracle.xdo.XDOException: java.lang.reflect.InvocationTargetException for some reports. Some other reports are working fine after upgrade. After reading more in Oracle support site, I found that there is a bug 13827022 in version 11.1.1.5 for div function which all of my failed reports are using it. The working reports are not using div function. Patch p13879917_11g_Generic and p14691557_11g_Generic were applied to our server. After apply these patches, div function is working but subtraction is not working unless I have to use div function before subtraction.
