Oracle – ORA-28000: the account is locked error getting frequently


I am facing this error given below :

 ORA-28000: the account is locked 

Is this a DB Issue ? Whenever I unlock the user account using the alter SQL query, that is ALTER USER username ACCOUNT UNLOCK, it will be temporarily OK.

Then after sometime the same account gets locked again. The database is using oracle XE version. Does anybody else have the same issue?

One of the reasons of your problem could be the password policy you are using.

And if there is no such policy of yours then check your settings for the password properties in the DEFAULT profile with the following query:

SELECT resource_name, limit
FROM dba_profiles 
WHERE profile = 'DEFAULT'
AND resource_type = 'PASSWORD';

And If required, you just need to change the PASSWORD_LIFE_TIME to unlimited with the following query:
