在Oracle数据库操纵中,登录Oracle账号时提示失败,并且Oracle账号频繁被锁定,本文将介绍如何解决此问题

在Oracle数据库操纵中,登录Oracle账号时提示失败,并且Oracle账号频繁被锁定。造成此故障的原因是什么呢?本文就介绍了这一过程,经由过程慢慢排查我们就能找到该故障的原因了。
下面记录下查找这个题目的步调。
1. 找到账号被锁按时候
哄骗sqlplus或者sqldeveloper,查询账号被锁定的时候,相干语句如下:
--批改当前会话的日期显示格局
alter session set nls_date_format = ""yyyy-MM-dd hh24:mi:ss"";
--查询被锁定账号的锁按时候
username,lock_date dba_users where username like ""TRSEKPV65_DEMO"";
比如这里的查询到的锁按时候为:20:03:03

2. 找到oracle的安装目次
项目组常识库的oracle安装路径为:C:\devsoftware\oracle11g

3. 找到监听日记
找到
C:\devsoftware\oracle11g\diag\tnslsnr\DEV2-216\listener\trace\listener.log文件,该文件会记录oracle的一些跟踪信息

4. 查看监听日记
找到该文件后,发明很大,无法用editplus打开。把该文件上传到linux机械或者在windows机械高低载一个tail.exe法度,履行tail -20 listener.log号令,查看该文件的最后20行内容。

5. 定位题目
按照上方查询到的时候,在日记中找到对应的时候地位,可以定位到当前时候Oracle所履行的操纵。
01-8月 -2011 20:03:35 * (CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=portalteam)(CID=(PROGRAM=D:\TRS\TRSGateway4.6\gwserver_x64\TrsAgent.exe)(HOST=DEV2-216)(USER=Administrator))) * (ADDRESS=(PROTOCOL=tcp)(HOST=fe80::e816:9e03:60ac:fdaa%11)(PORT=13678)) * establish * portalteam * 0

6. 总结
从上边可以看到,造成Oracle的账号被锁定的原因是由” TrsAgent.exe”过程造成的。细心一想,本来批改了暗码,没有批改GateWay的登录信息,所以造成了该账号登录Oracle经常失败,因为我们设备了Oracle的最大容许登录错误次数为10,所以跨越10次错误后账号将被锁定。
