1.用Xshell遠程連接安裝數據庫的服務器,切換到安裝oracle數據庫的用戶下,(我的oracle數據庫就安裝在oracle用戶下)
命令: su - oracle;
2.進入oracle控制台
命令: sqlplus /nolog;
以dba角色進入
命令: conn /as sysdba;
3.連接成功后,查看用戶列表
命令: select username from dba_user;
4.若修改某一個用戶密碼,修改用戶口令格式為: alter user username identified by newpassword;
例如修改用戶demo的密碼:
命令: alter user demo identified by demo123;
5.修改成功
以下為修改詳細過程:
