客戶端使用錯(cuò)誤的用戶密碼登陸數(shù)據(jù)庫(kù)

查詢最近1天由于密碼錯(cuò)誤登陸失敗的信息

查詢當(dāng)前審計(jì)中有哪些returncode值

1. 客戶端使用錯(cuò)誤的用戶密碼登陸數(shù)據(jù)庫(kù)

PS C:\Users\Administrator> sqlplus jingyu/ludan@jingyuSQL*Plus: Release 11.2.0.1.0 Production on 星期一 9月 7 11:28:08 2015Copyright (c) 1982, 2010, Oracle. All rights reserved.ERROR: ORA-01017: invalid username/password; logon denied

2. 查詢最近1天由于密碼錯(cuò)誤登陸失敗的信息

select sessionid, userid, userhost, comment$text, spare1, ntimestamp#from aud$where returncode = 1017and ntimestamp# > sysdate - 1;

查詢結(jié)果如下：

22479 JINGYU WORKGROUP\WIN-3KBILBGK27B Authenticated by: DATABASE; Client address: (ADDRESS=(PROTOCOL=tcp)(HOST=192.168.99.12)(PORT=49843)) Administrator 07-SEP-15 03.28.05.293986 AM

可以根據(jù)查詢結(jié)果定位到是哪臺(tái)機(jī)器使用錯(cuò)誤的用戶密碼嘗試登陸數(shù)據(jù)庫(kù)。

3. 查詢當(dāng)前審計(jì)中有哪些returncode值

SQL> select distinct returncode from aud$;RETURNCODE ----------2002101719201005028009280007 rows selected

查詢這些值對(duì)應(yīng)的相關(guān)錯(cuò)誤信息：

[oracle@JY-DB01 u01]$ oerr ora 28009 28009, 00000, "connection as SYS should be as SYSDBA or SYSOPER" // *Cause: connect SYS/<password> is no longer a valid syntax // *Action: Try connect SYS/<password> as SYSDBA or // connect SYS/<password> as SYSOPER // [oracle@JY-DB01 u01]$ oerr ora 28000 28000, 00000, "the account is locked" // *Cause: The user has entered wrong password consequently for maximum // number of times specified by the user's profile parameter // FAILED_LOGIN_ATTEMPTS, or the DBA has locked the account // *Action: Wait for PASSWORD_LOCK_TIME or contact DBA [oracle@JY-DB01 u01]$ oerr ora 1017 01017, 00000, "invalid username/password; logon denied" // *Cause: // *Action: [oracle@JY-DB01 u01]$ oerr ora 1920 01920, 00000, "user name '%s' conflicts with another user or role name" // *Cause: There is already a user or role with that name. // *Action: Specify a different user name.
