Oracle杀掉系统进程描述

在导入附件表AFFIX的时候,数据量很小就1w多条数据,但是AFFIX中有一个blob的大字段,这就使得查询起来很慢,因为工作的环境网络特别的不稳定,开始导入了大概快一半了,突然网络断了,当时真的很生气,但是也没有什么办法,网络好后接着导入此时总是出现导入错误、甚至导入了很长时间,数据条数根本没发生变化,就是这样的反反复复,查看了一下Oracle锁表的情况:
结果就看到如下结果:
果然有表锁死了,,心想kill掉锁死的表很简单,命令如下:
执行的时间很长,后来居然出现了下图的错误:
一看就是报错了,查了一些资料是因为oracle锁死的表被杀死后,状态被标识为“killed”但是锁定资源很长时间才能得到释放,有的时候实在没有别的好的办法我们就需要重启数据库了,我的理解是如果等半天或者更长时间的话是可以被释放的。于是就开始查询资料、例子,解决办法如下:
此时可以得到 PADDR ,在通过SQL得到:
这个时候就可以直接在系统中把oracle进程杀掉了,可以使用 kill -9 SPID 或者 ORAKILL SID SPID
此时整个操作完成,如果遇到此类问题不能解决大家在一起讨论。
