Hello All,
I logged into Oracle 10 using sqlplus / as sysdba
I am trying to alter user SYS or SYSMAN, and each time I am getting the following error:

SQL> alter user sys identified by password;
alter user sys identified by password
*
ERROR at line 1:

Please help, and thank you for your help in advance.

This issue was because there was a trigger that was enabled.
I have been able to resolve the issue by setting below to false
Alter system set "_system_trig_enabled"=FALSE
change the password and
Alter system set "_system_trig_enabled"=TRUE
