修改用户错误密码尝试次数为无限次

以下百度复制来的：

具体修改方法：
1、修改FAILED_LOGIN_ATTEMPTS的值
SQL>select * from dba_profiles where RESOURCE_NAME='FAILED_LOGIN_ATTEMPTS';
PROFILE              RESOURCE_NAME                  RESOURCE LIMIT
-------------------- ------------------------------ -------- ----------
DEFAULT              FAILED_LOGIN_ATTEMPTS          PASSWORD 10
SQL> alter profile default limit failed_login_attempts 100;
SQL> select * from dba_profiles where RESOURCE_NAME='FAILED_LOGIN_ATTEMPTS';
PROFILE              RESOURCE_NAME                  RESOURCE LIMIT
-------------------- ------------------------------ -------- ----------
DEFAULT              FAILED_LOGIN_ATTEMPTS          PASSWORD 100
2、修改为无限次尝试
SQL> alter profile default limit failed_login_attempts unlimited;
SQL> select * from dba_profiles where RESOURCE_NAME='FAILED_LOGIN_ATTEMPTS';
PROFILE              RESOURCE_NAME                  RESOURCE LIMIT
-------------------- ------------------------------ -------- ----------
DEFAULT              FAILED_LOGIN_ATTEMPTS          PASSWORD UNLIMITED
