"how to access oracle database over network?" Code Answer


whenever you are sufering with this kind of errors while creating remote access for you database, do following things before.

  1. create a listener using net manager tool of oracle or create it manually.
  2. after generating listener, check out "listener.ora" [located : oracle_installed_dirproduct11.2.0dbhome_1networkadmin] file, for your entry. (is there any entry for the listener which you have created just before. if you found your entry than and than do next steps otherwise do it from first step.)
  3. if you found the entry for your listener, open command prompt and fire command lsnrctl status. this will give you all currently running listeners list, find out the one which you created just before.
  4. check out the host name and port number for your listener.
  5. generate the connection string as per the details you found in lsnrctl status
