Oracle 管理用戶
用戶的驗證方式:數據庫,操做系統,網絡。
建立用戶(數據庫驗證):
SQL> create user simon identified by password
2 default tablespace users
3 temporary tablespace temp
4 quota 1m on users;
User created.
建立用戶(操做系統驗證):
SQL> create user root
2 identified externally
3 default tablespace users
4 temporary tablespace temp
5 quota 1m on users;
User created.
兩個初始化參數文件:
remote_os_authent=true 表示用戶能夠由遠程系統驗證身份
os_authent_prefix=ops$ 用戶能夠由操做系統或Oracle服務器驗證身份
刪除用戶:
SQL> drop user simon;
User dropped.
顯示用戶:
SQL> select username,default_tablespace from dba_users;
