我们的ORA-07445，根据DUMP文件分析，多半是因为乱码问题照成的，然后修改了服务器的字符集。（即添加export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK）。然后跟进我们这个包MONITOR.PACKAGE_GARBAGEDISTRIBUTING。一切OK了。

总结：乱码问题也可以导致ora-07445问题。遇到问题沉着冷静，细心才可以把问题解决好。

天哪，真是DEBUG状态！
一个因为在DEBUG状态，且是基于DELETE的TRIGGER触发了这个Oracle的BUG！
......
现在要么改这个TRIGGER的状态，要么打补丁（9.2.0.6）。第一种选择是明智而快捷且安装的。重新编译，检查不是DEBUG状态。应用启动，正常运行
