没事装了个11g玩,安装软件dbca建库使用一切正常。今天启动发现报错

[Oracle@OEL54db11gR2 dbs]$ sqlplus / as sysdba

SQL*Plus: Release 11.2.0.1.0 Production on Thu Nov 22 20:07:45 2012

Connected to an idle instance.

SQL> startup

ORA-27102: out of memory

Linux Error: 22: Invalid argument

处理流程如下:

1、查看数据库内存大小

[oracle@OEL54db11gR2 ~]$ cd /u01/app/oracle/product/11.2.0/db_1/dbs/

[oracle@OEL54db11gR2 dbs]$ ls

hc_DBUA0.dat init.ora orapworcl peshm_orcl_0

hc_orcl.dat lkORCL peshm_DBUA0_0 spfileorcl.ora

[oracle@OEL54db11gR2 dbs]$ cat spfileorcl.ora

2、切换到root用户,查看内核内存大小

[oracle@OEL54db11gR2 ~]$ su -
