查系统默认的策略，连续验证 10 次错误帐户即会被锁

SQL> select resource_name, limit from dba_profiles where profile=’DEFAULT’;

RESOURCE_NAME LIMIT
——————————– —————————————-
COMPOSITE_LIMIT UNLIMITED
SESSIONS_PER_USER UNLIMITED
CPU_PER_SESSION UNLIMITED
CPU_PER_CALL UNLIMITED
LOGICAL_READS_PER_SESSION UNLIMITED
LOGICAL_READS_PER_CALL UNLIMITED
IDLE_TIME UNLIMITED
CONNECT_TIME UNLIMITED
PRIVATE_SGA UNLIMITED
FAILED_LOGIN_ATTEMPTS 10
PASSWORD_LIFE_TIME 180

RESOURCE_NAME LIMIT
——————————– —————————————-
PASSWORD_REUSE_TIME UNLIMITED
PASSWORD_REUSE_MAX UNLIMITED
PASSWORD_VERIFY_FUNCTION NULL
PASSWORD_LOCK_TIME 1
PASSWORD_GRACE_TIME 7

16 rows selected.

查看用户被锁状态

SQL> select username,account_status from dba_users where username=’USER1′;

USERNAME ACCOUNT_STATUS
—————————— ——————————–
USER1 LOCKED(TIMED)
SQL> select name,lcount from user$ where name=’USER1′;

NAME LCOUNT
—————————— ———-
USER1 10

先处理问题，将验证错误次数改为不受限制，解锁用户

SQL> alter profile default limit FAILED_LOGIN_ATTEMPTS unlimited;

Profile altered.

SQL> alter user user1 account unlock;

User altered.

再查看用户验证的错误次数，如果此帐户一直在验证，可以看到次数一直在增加

SQL> select name,lcount from user$ where name=’USER1′;

通过日志文件 /u01/app/Oracle/diag/tnslsnr/localhost/listener/alert/log.xml 追查请求来源 ip，但是效果不理想

1. 看不到请求的用户名，看不到请求结果，对请求来源 ip 判断可能有误

2. 日志过多，暂时想不到关键字过滤

设置格式，查 returncode 为 1017 的，可以很清楚看到验证的用户 (userid) 计算机名 (userhost，局域网有用) 请求来源 ip(comment$text)

SQL> set pagesize 100;
SQL> set linesize 150;
