the tnsnames.ora file and ensure that it points to the correct server and port. If the Forms server is on another machine, test the TNS resolve with tnsping from the command prompt. Finally, check the listener. First, ensure that your listener service is running. C:\Documents and Settings\ME>lsnrctl stat This should show the status of the listener and the services it is listening for. Remember that when you run SQL*Plus on the database server, it does not need the listener to connect unless you specify the database tnsnames.ora entry.Try to start the listener service using lsnrctl from DOS prompt. set ORACLE_HOME= cd %ORACLE_HOME%/bin lsnrctl start LISTENER If the listener service is not running, re-start the listener service using the Windows task manager or use the DOS command line utility to re-start the Windows service with the "net start" command: C:\Documents and Settings\ME>net start OracleOraDb10g_home1TNSListener You can use the lsnrctl status command to verify that the listener is down, and lsnrctl start to start your listener.

This can be due to the listener not being started or being incorrectly configured, or it can be due to a network connection problem. Solution Two likely reasons for the error: the database was briefly unavailable at the time when you tried to access. the Oracle client application on your machine is not configured correctly.
