1.用dba角色的用户登录,进行解锁,先设置具体时间格式,一边查看具体时间
SQL> alter session set nls_date_format='yyyy-mm-dd hh24:mi:ss';
Session altered.
2.查看具体的被锁时间
SQL> select username,lock_date from dba_users where username='TEST';
USERNAME LOCK_DATE
TEST 2009-03-10 08:51:03
3.解锁
SQL> alter user test account unlock;
User altered.
4.查看具体是哪个ip造成用户被锁
查看$ORACLE_HOME/network/admin/log/listener.log日志
10-MAR-2009 08:51:03 * (CONNECT_DATA=(SID=lhoms)(SERVER=DEDICATED)(CID=(PROGRAM=oracle)(HOST=omstestdb)(USER=oraoms))) * (ADDRESS=(PROTOCOL=tcp)(HOST=10.69.1.11)(PORT=49434)) * establish * lhoms * 0
10-MAR-2009 08:51:03 * (CONNECT_DATA=(SID=lhoms)(SERVER=DEDICATED)(CID=(PROGRAM=oracle)(HOST=omstestdb)(USER=oraoms))) * (ADDRESS=(PROTOCOL=tcp)(HOST=10.69.1.11)(PORT=49435)) * establish * lhoms * 0
这样可知是上面10.69.1.11的ip尝试多次失败登陆造成的被锁
注:
一般数据库默认是10次尝试失败后锁住用户
1、查看FAILED_LOGIN_ATTEMPTS的值
select * from dba_profiles
2.修改为30次
alter profile default limit FAILED_LOGIN_ATTEMPTS 30;
3.修改为无限次(为安全起见,不建议使用)
alter profile default limit FAILED_LOGIN_ATTEMPTS unlimited;
