How do I turn off Oracle password expiration?

Question

I\'m using Oracle for development. The password for a bootstrap account that I always use to rebuild my database has expired.

How do I turn off password expiration

Answer 1

I will suggest its not a good idea to turn off the password expiration as it can lead to possible threats to confidentiality, integrity and availability of data.

However if you want so.

If you have proper access use following SQL

SELECT username, account_status FROM dba_users;

This should give you result like this.

   USERNAME                       ACCOUNT_STATUS
------------------------------ -----------------

SYSTEM                         OPEN
SYS                            OPEN
SDMADM                         OPEN
MARKETPLACE                    OPEN
SCHEMAOWNER                    OPEN
ANONYMOUS                      OPEN
SCHEMAOWNER2                   OPEN
SDMADM2                        OPEN
SCHEMAOWNER1                   OPEN
SDMADM1                        OPEN
HR                             EXPIRED(GRACE)

USERNAME                       ACCOUNT_STATUS
------------------------------ -----------------

APEX_PUBLIC_USER               LOCKED
APEX_040000                    LOCKED
FLOWS_FILES                    LOCKED
XS$NULL                        EXPIRED & LOCKED
OUTLN                          EXPIRED & LOCKED
XDB                            EXPIRED & LOCKED
CTXSYS                         EXPIRED & LOCKED
MDSYS                          EXPIRED & LOCKED
