  • Thank you for your response.... But I have already done this and my database is working fine all the entries are inserted through it.. but my query is am not able to open database application window.... in case if want to view the list of tables and the entries to it in my database. how can i do so??? I have actually forgot the login details of my database.... can you help me to get that back???

  • You are getting ORA-12560: TNS:protocol adaptor error becuase of the following:

    1. Oracle_Sid is not property set(especially on windows), it is in manual mode
    2. Database services is not started

    Solution to this:

    1. To set Oracle_Sid in automatic mode. Go to Start>Run> type "services.msc". Select OracleServiceORCL(or OracleServiceSID), double click and change startup to Automatic.

    2. To start Database services. Go to Start>Run> type "services.msc". Select the OracleServiceXE name, Right Click and Start.
