You tried to log in to the SAP system but encountered with error, “SAP System Message: No connect to database, session terminated”.
Solution
• Log in to the operating system level and check the database is up and running. For Oracle, ensure the listener is running fine.
• Check the developer trace message logs, especially on dev_w0 for any related errors.
• Last resort, clean restart SAP and database!
I am using SAP
i tried restarting also… but still find the same problem
Please check the error from the alert log as well.
