Default password and modification for oracle users

It takes too long to log on to the database using the default password. If you do not want to remember the password, you can use the following method to change the Sys user password and use sqlplus to log on to sqlplus/As sysdba. After you log on to the database using show user, you can see sys. user, because the System user logs on to the system using OS verification by default, and does not check the password. if you want to modify the password, run alter user SYS identified by newpass after entering sqlplus. newpass is the password you want to set [Oracle @ kfcs ~]. $ Sqlplus/As sysdbasql * Plus: Release 10.2.0.4.0-production on Wed Apr 17 09:25:09 2013 copyright (c) 1982,200 7, Oracle. all rights reserved. connected to: Oracle Database 10g Enterprise Edition Release 10.2.0.4.0-productionwith the partitioning, OLAP, data mining and real application testing optionssql> show user; user is "sys" SQL> alter user SYS identified by change_on_install; user altered.
