But the main problem I still have is that I cannot access my database on another computer using my laptop as the server and the other one as the client. I also want to access it via the internet apart from using the LAN cable connection. I do not know how. I posted it on Apex Forum. A solution was sent to me by one contributor, which worked with the following code: EXEC DBMS_XDB.SETLISTENERLOCALACCESS(FALSE); on the LOCAL AREA NETWORK connection initially.I later had problem with my laptop so I did new window intallation by first formatting the computer. Thereafter, when I installed Apex 11g, inspite of using the above code, I cannot access the application on another computer as before.
Should enable the access from other PCs.
EXEC DBMS_XDB.SETLISTENERLOCALACCESS(FALSE); COMMIT;
