    Unanswered: ORA-12560: TNS: protocol adapter error

    Dear all

    I installed

    - "Oracle Database 10g Release 2 ( for Microsoft Windows" and
    - "Oracle Developer Suite 10g ( for Microsoft Windows"

    My OS is Windows 2000 pro.

    I can login to the database by scott/tiger through OraDb10g_Home, Application Development, Sql plus.

    But when I try to login to the database through the DevSuiteHome (Sql plus, Forms Builder, Report Builder and Oracle Designer ) I receive this message:

    ORA-12560: TNS: protocol adapter error

    Any body helps me??

    Thanks in Advance

    Go to \network\admin directory into which you installed Oracle database. Take TNSNAMES.ORA, SQLNET.ORA and LISTNER.ORA and copy them into the \network\admin directory into which you installed Developer Suite. Don't forget to make backup copies of the Developer Suite .ORA files first!
