昨天刚刚将oracle 11G安装完成，今天想通过sqlplus来连接数据库，在启动oracle时，突然报错：

ORA-01078: failure in processing system parameters
LRM-00109: could not open parameter file '/u01/app/oracle/product/11.1.0/db_1/dbs/initDATATEST.ora'

[oracle@datatest ~]$ sqlplus "/as sysdba"

SQL> startup
ORA-01078: failure in processing system parameters
LRM-00109: could not open parameter file '/u01/app/oracle/product/11.1.0/db_1/dbs/initDATATEST.ora'

原来打不开initDATATEST.ora，于是进入/u01/app/oracle/product/11.1.0/db_1/dbs/目录，

[oracle@datatest ~]$ cd /u01/app/oracle/product/11.1.0/db_1/dbs/
[oracle@datatest dbs]$ ls
hc_datatest.dat  hc_mm.dat  initdw.ora  init.ora  lkMM  orapwmm  spfilemm.ora

原来是没有initDATATEST.ora文件

解决此问题的方法就是到cd /u01/app/oracle/admin/datatest/pfile/目录下，将ora.1114201016265复制到dbs目录下：

cp init.ora.1114201016265 /u01/app/oracle/product/11.1.0/db_1/initDATATEST.ora

mv init.ora.1114201016265  initDATATEST.ora

然后再次用sqlplus连接数据库

[oracle@datatest dbs]$ sqlplus "/as sysdba"

SQL*Plus: Release 11.1.0.6.0 - Production on Wed Dec 15 11:04:25 2010

OK,可以了

如还是报错。也可将SPFILE文件重新建立。
