在linux下修改oracle的sys和system的密码以及默认密码

1、再linux系统上sqlplus '/as sysdba'

进入sqlplus后就可以修改sys和system的密码了

2、alter user sys identified by "密码"

alter user system identified by "密码"

其实就是先登录到oracle然后，在里面进行修改。

 

=====

默认的密码是

# sqlplus ‘/ as sysdba’

alter user system identified by manager;

alter user sys identified by change_on_install;
