Sys and system schema are expired & locked after doing disaster recovery.

Hi All,
In one of our development database, I performed disaster recovery and it was successfull.
After completing thre recovery, sys and system schema are expired & locked.
So, I am not able to perform any kind of operation which is performed by sys and system user.
Database Version : 11g r2
Operating system : Red hat 5.5
Please kindly suggest me, How can i solve this problem?
Thanks,
Viren Patel.

This is some sort of a mirracle. SYS even if expired and locked - can login:
SQL> SELECT d.username, u.account_status
  2  FROM DBA_USERS_WITH_DEFPWD d, DBA_USERS u
  3  WHERE d.username = u.username and u.username=’SYS’
  4  ORDER BY 2,1;
USERNAME                       ACCOUNT_STATUS
SYS                            OPEN
SQL> alter user sys account lock;
User altered.
SQL> alter user sys password expire;
User altered.
SQL> quit
