這篇文章主要介紹“Oracle自動鎖住不經(jīng)常使用的用戶指的是什么”的相關(guān)知識,小編通過實際案例向大家展示操作過程,操作方法簡單快捷,實用性強,希望這篇“Oracle自動鎖住不經(jīng)常使用的用戶指的是什么”文章能幫助大家解決問題。
Starting with this release, you can configure user accounts to automatically lock if they have been inactive over a period of time.
The CREATE USER and ALTER USER SQL statements enable you to set a new profile parameter, INACTIVE_ACCOUNT_TIME, which enables you to automatically lock inactive accounts.
從12.2開始,Oracle會自動將不活躍(超過一定時間沒有操作)的用戶鎖住。該時間是通過參數(shù)INACTIVE_ACCOUNT_TIME
來設(shè)置的。
該參數(shù)單位:天。表示從該用戶上次成功登陸開始計算,如果超過參數(shù)設(shè)定的天數(shù),那么Oracle會自動鎖住該用戶。
該參數(shù)默認(rèn)是UNLIMITED,需要手動開啟。
SQL> select profile,resource_name,limit from dba_profiles t where t.resource_name='INACTIVE_ACCOUNT_TIME'; PROFILE RESOURCE_NAME LIMIT ------------------------------ ------------------------------ -------------------- DEFAULT INACTIVE_ACCOUNT_TIME UNLIMITED ORA_STIG_PROFILE INACTIVE_ACCOUNT_TIME 35 TEST_PROFILE INACTIVE_ACCOUNT_TIME 35
關(guān)于該參數(shù)的更多說明:
INACTIVE_ACCOUNT_TIME默認(rèn)值是UNLIMITED,也就是不啟用自動鎖用戶.
參數(shù)值是15到24855之間.
如果不想自動鎖用戶,則需要把 INACTIVE_ACCOUNT_TIME參數(shù)值設(shè)置為UNLIMITED.
想將該參數(shù)時間設(shè)置為默認(rèn)PROFILE中指定的參數(shù)值,可設(shè)置 INACTIVE_ACCOUNT_TIME 參數(shù)值為 DEFAULT.
You can set this parameter for all database authenticated users, including administrative users, but not for external or global authenticated users.
In a read-only database, the last successful login is not considered in the INACTIVE_ACCOUNT_TIME timing. It is not possible to lock a user account in a read-only database (except by performing consecutive failed logins equal in number to the account’s FAILED_LOGIN_ATTEMPTS password profile setting).
For a newly created user account, the timing begins at account creation time. When this user logs out and then logs again, the timing starts when the user successfully logs in.
In a multitenant environment, the INACTIVE_ACCOUNT_TIME setting applies to the last time a common user logs in to the root. A common user is considered active if this user logs in to any of the PDBs or the root.
For a proxy user account login, the INACTIVE_ACCOUNT_TIME begins the timing when the proxy user logs in successfully.
