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

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
C"挌m盈/CC"6Porcl.__db_cache_size=205520896

2、切换到root用户,查看内核内存大小
[oracle@OEL54db11gR2 ~]$ su -
