During our development if we wanted to check the report level UI changes, sometimes we will not see the changes immidiately. This is due to Presentation Server Cache. Eventhough we disable the BI Server cache, It doesnt make any effect on presentation Server objects.
So in that situations we need to disable Presentation server cache permanently across OBI Application, To do this add the following parameters in instaceconfig.xml. (Make sure that you have taken a backup copy of instanceconfig.xml)
Now restart the OBI Presentation server service and test the results.
Note: Keep in mind that this parameters cause Presentation Server to always bypass its cache. To be used only for testing – may have serious performance implications.
