Validating Guest user password

We generally come across a situation where we have to validate our Guest user password. I am mentioning some steps via backend to validate your Guest user password.
1. Check Value in DBC File
grep -i GUEST_USER_PWD $FND_SECURE/hostname_SID.dbc
GUEST_USER_PWD=GUEST/ORACLE

2. Check profile option value
sqlplus apps/passwd
SQL> select fnd_profile.value(’GUEST_USER_PWD’) from dual;
FND_PROFILE.VALUE(’GUEST_USER_PWD’)
——————————————————————————–
GUEST/ORACLE

Value for step 1 and 2 must be sync.

3. Guest user connectivity check
sqlplus apps/passwd
SQL> select FND_WEB_SEC.VALIDATE_LOGIN('GUEST','ORACLE') from dual;
FND_WEB_SEC.VALIDATE_LOGIN('GUEST','ORACLE')
——————————————————————————–-----
Y

Above is the value, then everything is perfect.
Happy Troubleshooting !!!
