ORA-7445(koioapm)错误

原创 Linux操作系统 作者:yangtingkun 时间:2008-03-14 23:50:49 0 删除 编辑

这个错误发生在11.1.0.6版本中。简单记录一下bug的现象。

 

 

首先记录一下错误信息:

Fatal NI connect error 12532, connecting to:
 (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=172.25.4.70)(PORT=1521))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=ora11g_s.ytk-thinkpad)(CID=(PROGRAM=oracle)(HOST=yangtk.ytk-thinkpad)(USER=oracle))))

  VERSION INFORMATION:
        TNS for Linux: Version 11.1.0.6.0 - Production
        TCP/IP NT Protocol Adapter for Linux: Version 11.1.0.6.0 - Production
  Time: 05-SEP-2007 18:57:32
  Tracing not turned on.
  Tns error struct:

问题发生在主库尝试归档到STANBY数据库失败之后。自错误发生之后,每次尝试连接STANDBY数据库报错后,都会出现这个7445错误。且主库重启之后,问题消失。

根据上面的信息判断,初步断定和STANDBY环境有关。由于问题无法重新,猜测是由于某些状态不正确引起的。

7445错误的trace文件中找不到什么有价值的信息:

由于是新版本的bug,目前查询metalink也没有找到任何相关的记录。
