通过OCI8 PHP检查oracle密码是否已过期/无效

Question

Is there a way to check if Oracle Database password is expired or invalid using OCI8 in a PHP file without locking the DB user for invalid attempt? (PS: My database user gets locked after 3 invalid attempts)

Answer 1

If you connect to Oracle database as a privileged user (such as SYS) and check DBA_USERS:

SQL> desc dba_users;
 Name
 --------------------------------
 USERNAME
 USER_ID
 PASSWORD
 ACCOUNT_STATUS
 LOCK_DATE
 EXPIRY_DATE               --> this
 DEFAULT_TABLESPACE
 TEMPORARY_TABLESPACE
 CREATED
 PROFILE
 INITIAL_RSRC_CONSUMER_GROUP
 EXTERNAL_NAME
 PASSWORD_VERSIONS
 EDITIONS_ENABLED
 AUTHENTICATION_TYPE

SQL>

you'll see the EXPIRY_DATE so - check that value.

As of "invalid password": I think that you don't have to worry about it as Oracle won't let you store an invalid password anyway.
