今天一同事做提交数据库的时候提示内存不足了，再过一会发现监听自动停止了。打开预警日志发现如下错误：

在网上搜了下，看来还挺多人碰到这个错误的，目前我们的这个数据库是安装在windows系统32位的，而且oracle的版本是10.2.0.1，看来真是oracle的bug了。
解决方法：
1) Reduce the amount of SGA needed to be allocated for the database. 2) Limit the number of dedicated connections to the database and the amount of memory each user process will consume. 3) Change from dedicated connections to multi-threaded server (MTS) connections as MTS only uses a fraction of the amount of memory allocated to each user process when initial connection to the database is established.
