Non-PROD instance clone has been completed successfully from PROD instance and no issues were encountered while performing the clone but, while trying to login into the application front end, we are unable to login and below is the error message from the log files.
Issue:
After the NON-PROD instance clone, while logging into the application in R12.2.4 we are getting the blank page, below is the error noticed in the log files.
javax.servlet.ServletException: java.lang.Exception: java.lang.RuntimeException: Guest user/pwd does not exist or match: GUEST/ORACLE
Cause:
This could be because of the Oracle executable failed to re-link. FND_WEB_SEC is unable to execute the code to change the GUEST user password in the database due to corrupted JVM.
SQL> select FND_WEB_SEC.VALIDATE_LOGIN(‘GUEST’,'<PASSWORD>’) from dual;
FND_WEB_SEC.VALIDATE_LOGIN(‘GUEST’,'<PASSWORD>’)
