RMAN-04009: warning from auxiliary database: ORA-28002: the password will expire within 6 days

I have come across an issue when trying to duplicate a database by connection to Recovery catalog database. You will come across this warning when the user profile has reached PASSWORD_LIFE_TIME value limit and you have entered into PASSWORD_GRACE_TIME value

RMAN-04009: warning from auxiliary database: ORA-28002: the password will expire within 6 days

First check the profile that user has been assigned.

SQL> select username , profile from dba_users where username=’RMAN’;
username profile
------------- ---------------
RMAN DEFAULT

Check the current status of the user
SQL> select USERNAME, ACCOUNT_STATUS from dba_users where USERNAME = ‘RMAN’;
USERNAME ACCOUNT_STATUS
------------- ----------------- --------------------------------
RMAN EXPIRED(GRACE)

Check the RESOUCE_NAME, LIMIT for the Default profile.
SQL> select RESOURCE_NAME,LIMIT from dba_profiles where PROFILE='DEFAULT';

RESOURCE_NAME LIMIT
---------------------------  -------------------------------------------------
COMPOSITE_LIMIT UNLIMITED
SESSIONS_PER_USER UNLIMITED
CPU_PER_SESSION UNLIMITED
CPU_PER_CALL UNLIMITED
LOGICAL_READS_PER_SESSION UNLIMITED
LOGICAL_READS_PER_CALL UNLIMITED
IDLE_TIME UNLIMITED
CONNECT_TIME UNLIMITED
PRIVATE_SGA UNLIMITED
FAILED_LOGIN_ATTEMPTS 10
PASSWORD_LIFE_TIME 180
RESOURCE_NAME LIMIT
PASSWORD_REUSE_TIME UNLIMITED
PASSWORD_REUSE_MAX UNLIMITED
PASSWORD_VERIFY_FUNCTION NULL
PASSWORD_LOCK_TIME 1
PASSWORD_GRACE_TIME 7
INACTIVE_ACCOUNT_TIME UNLIMITED

As we see password PASSWORD_LIFE_TIME set to 180 days

First you need to change the password for the issue to resolve.
SQL> Alter user rman identified by rman_new_password;

As current password life time set 180 days, You can change the password life time to avoid this issue in future. Either you can set to specific number of days or UNLIMITED.

SQL> ALTER PROFILE DEFAULT LIMIT PASSWORD_LIFE_TIME UNLIMITED;
Profile altered.

You can check the modified resource limit for PASSWORD_LIFE_TIME
SQL> select RESOURCE_NAME,LIMIT from dba_profiles where PROFILE='DEFAULT' and RESOURCE_NAME='PASSWORD_LIFE_TIME';

RESOURCE_NAME   LIMIT
---------------------------  -------------------------------------------------
PASSWORD_LIFE_TIME UNLIMITED

Hope this helps
