     然后就开始查看物理磁盘使用情况,是那个目录下的文件占用了大量的磁盘空间(du -sh /home/),最终在$ORACLE_HOME/dbs目录下找到了大量的数据文件

    看到这些文件之后,我有点懵;在Linux下创建表空间,数据文件命名上居然按照windows下来写;看了他们开发人员写的代码之后,原来是创建表空间的时候,没有指定具体的绝对路径,同时命名时候,居然是用windows下的路径风格来。接下来就是如何先解决数据库刮起的问题吧。

    首先,找到一个个头大点的,无关紧要的文件,先挪动到其他系统上去;这时,数据库挂起的问题得到解决(只要你腾出空间来,Oracle会自动恢复回来)

    其次,登陆Oracle,根据业务需要,适当调整一些数据表空间的位置,或者直接删除一些不必要的表空间。这个就要看具体情况了;

    最后,问题得到解决.
