Set oracle user password to never expire

Modifying the oracle user password never expires. It is convenient to use in the test environment. This setting should not be set in a production environment.

method/step

1. Check which user's proifle is, usually default:

   sql>SELECT username,PROFILE FROM dba_users;

2. View password expiration settings for a specified profile (such as default):

   sql>SELECT * FROM dba_profiles s WHERE s.profile='DEFAULT' AND resource_name='PASSWORD_LIFE_TIME';

3. Change the password validity period from the default 180 days to "unlimited":

   ALTER PROFILE DEFAULT LIMIT PASSWORD_LIFE_TIME UNLIMITED;

   No need to restart the database after modification, it will take effect immediately.

4. 4

   After modification, accounts that have not been prompted with ORA-28002 warning will not encounter the same prompt again;

   Accounts that have been prompted must change their passwords again, for example:

    $sqlplus / as sysdba

   sql> alter user smsc identified by <original password> ---- no need to change the new password
