遇到ORA-3136的解决之道

今天早上同事打电话说日照业务库第二个节点登录不进去，业务没法使用，weblogic第二个节点测不通。

PLSQL登录就死住,最后是end-of-communcation chanel  ,估计出现了严重的数据库故障。

    telnet进AIX小机,crs_stat状态,发现第二个节点为unkown,用命令crs_start  启动此实例,结果启动失败,crs_stop倒是能

关闭此实例。

   开始动手找原因，在oracle的安装目录下admin文件中bdump的警告文件和udump的trace文件中：

 

Tue Jul 18 23:09:22 2006 WARNING: inbound connection timed out (ORA-3136) Tue Jul 18 23:09:23 2006 WARNING: inbound connection timed out (ORA-3136) Tue Jul 18 23:09:25 2006 WARNING: inbound connection timed out (ORA-3136) Tue Jul 18 23:09:30 2006 WARNING: inbound connection timed out (ORA-3136) Tue Jul 18 23:12:15 2006 WARNING: inbound connection timed out (ORA-3136)

同时在sqlnet.log中记录了如下错误:

Fatal NI connect error 12170. VERSION INFORMATION: TNS for Linux: Version 10.2.0.2.0 - Production Oracle Bequeath NT Protocol Adapter for Linux: Version 10.2.0.2.0 - Production TCP/IP NT Protocol Adapter for Linux: Version 10.2.0.2.0 - Production Time: 19-JUL-2006 11:25:26 Tracing not turned on.

在eygle的网站有解决办法：

 

这是和网络连接相关的一个错误,Metalink上给出了如下的解决方案:

1.set INBOUND_CONNECT_TIMEOUT_<listenername>=0 in listener.ora
2. set SQLNET.INBOUND_CONNECT_TIMEOUT = 0 in sqlnet.ora of server.
3. stop and start both listener and database.
4. Now try to connect to DB and observe the behaviour

详细的解决：

修改listener的inbound_connect_timeout参数的方法
方法一:

LSNRCTL> set save_config_on_stop on  #表示修改参数永久生效，否则只是临时生效，下次重启监听又还原为原来的值了
LSNRCTL> exit

方法二：
修改listener.ora文件，加入: INBOUND_CONNECT_TIMEOUT_LISTENER_NAME=0
问题解决

修改后依然是启动不了数据库，但在依然启动不了数据库连sqlplus环境都进不去，我查看来最新一个udump 下的

trc文件，其中有Dumping diagnostic information for LCK0:

依据此处和alterSID.log的内容：

可以判断是oracle内部的进程锁定的,上面的内容说的很清楚，就是422264      这个进程编号,

kill -9 422264 再进入sqlplus  "/as sysdba"  可以登录了，startup 数据库成功启动。

       看来解决问题还得具体问题具体分析,不过大佬们的文档还是需要借鉴的。
