Thank you for this very useful script. It made upgrading to Apex 4 a breeze. If I could make one little suggestion, it is to tell users that when they are propmpted for a value for '1', they are to supply the path to the oracle home.

Thanks - useful...got my EPG Apex 4 running on 11g now after this...did have an issue with the lsnrctl status|grep HTTP bit...it didn't show up initially...needed to wait a while for it to register...might want to note that.
