ORA-27101,ORA-27102 错误解决方法

错误提示如下

ORA-27101
shared memory realm does not exist

Cause:Unable to locate shared memory realm

Action:Verify that the realm is accessible

ORA-27102
out of memory

Cause:Out of memory

Action:Consult the trace file for details

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	复制代码
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。
