Straight forward error & resolution. In attempting to increase this parameter using 'alter system set ... scope=memory;', it worked successfully. 'show parameter' shows the new value. However, the application continues to fail and we can see it is hitting the old value as it shows in v$open_cursors & v$sesstat. Rebooting the instance resolve it as the new values takes effect. At least according to the official doc, this parameter is 'ISSYSMODIFIED' with a value of 'IMMEDIATE'. Rebooting the instance is not needed, but it does not appear to behave this way?
