ORA-12560 with installation of 9i Database and Developer Suite

I installed Oracle9i Database Personal Edition and Oracle9i Developer Suite. I received acknowledgement that the install was completed successfully; however, when trying to open the first form, I received the following error message: "The browser loaded the applet." Then I got: "ORA-12560: TNS: protocol adapter error." For connection to the database I used username "SCOTT" and password "tiger."

I installed Oracle9i Database Personal Edition and Oracle9i Developer Suite using these instructions. I received the acknowledgement that the install was completed successfully; however, when trying to open the first form, I received the following error message: "The browser loaded the applet." Then I got: "ORA-12560: TNS: protocol adapter error." For connection to the database I used username "SCOTT" and password "tiger." Any assistance will be appreciated.

Ensure that the Oracle database listener is running and that it allows connections to your database. To check if the listener is running, type:

lsnrctl status
… after setting your environment properly so that you are using the proper $ORACLE_HOME. If the database resides on a Windows server, you can open up the Service panel and see whether the listener service is running (it will be called something similar to OracleOraHome92TNSListener). If the listener is not running, it can be started as follows (assuming a default listener with no name):
lsnrctl start

Remember to set your environment to the proper $ORACLE_HOME first.

Test connectivity to your database by starting SQL*Plus from the desktop and providing the relevant information to connect. If connecting to the database with SQL*Plus is successful, but you are still having problems connecting via Forms, you may have to turn on SQL Net tracing to resolve the problem.
