今天在centos6上发现oracle shutdown&startup都起不来了，之前都好好的，报如下错：

代码如下

SQL> shutdown immediate

ORA-01034: ORACLE not available

ORA-27101: shared memory realm does not exist

Linux-x86_64 Error: 2: No such file or directory

SQL> startup

ORA-27102: out of memory

Linux-x86_64 Error: 12: Cannot allocate memory

Additional information: 1

Additional information: 1736716

Additional information: 8

然后根据这二个ora-去找啊找啊，没有进展，参数什么的也没有变化。

最后突然想起在server上开了一下vncserver这个恶心的家伙，但木有随手关了它，top一下，我去，吃了好多的CPU+内存，赶紧用root stop它，然后，就正常了
