从信息上看，是对pfile没有能够打开。
2、一次不成功的尝试
从日志信息上，看到是不能够打开文本参数控制文件。初步猜测是文件权限原因，下面进行检查。
[grid@SimpleLinux oraagent_grid]$ cd/u01/app/oracle/product/11.2.0/db_1/dbs/
[grid@SimpleLinux dbs]$ ls -l
total 20
-rw-rw---- 1 oracle asmadmin 1544 Sep 1212:58 hc_ora11g.dat
-rw-r--r-- 1 oracle oinstall 2851 May15 2009 init.ora
-rw-r----- 1 oracle oinstall 887 Sep 29 09:31 initora11g.ora
-rw-r----- 1 oracle asmadmin 24 Sep 12 12:58 lkORA11G
-rw-r----- 1 oracle oinstall 1536 Sep 1213:11 orapwora11g
[grid@SimpleLinux dbs]$ id oracle
uid=500(oracle) gid=500(oinstall)groups=500(oinstall),501(dba),502(oper),602(asmdba)
[grid@SimpleLinux dbs]$ id grid
uid=501(grid) gid=500(oinstall)groups=500(oinstall),501(dba),600(asmadmin),601(asmoper),602(asmdba)
权限内容是oracle用户读写、组用户读。从权限上看，grid和oracle读取和修改的问题不算特别严重。但是还是进行测试尝试。
[oracle@SimpleLinux dbs]$ chmod 770initora11g.ora
[oracle@SimpleLinux dbs]$ ls -l
total 20
-rw-rw---- 1 oracle asmadmin 1544 Sep 1212:58 hc_ora11g.dat
-rw-r--r-- 1 oracle oinstall 2851 May15 2009 init.ora
-rwxrwx--- 1 oracle oinstall 887 Sep 29 09:31 initora11g.ora
-rw-r----- 1 oracle asmadmin 24 Sep 12 12:58 lkORA11G
-rw-r----- 1 oracle oinstall 1536 Sep 1213:11 orapwora11g
尝试启动数据库。
[grid@SimpleLinux ~]$ srvctl start database-d ora11g

启动失败。那么，试着使用传统sqlplus命令行方式启动是否可行？
[oracle@SimpleLinux ~]$ sqlplus /nolog

启动成功，使用sqlplus命令行可以启动，但是Oracle Restart启动就会失败。那么问题在哪儿？
3、Spfile vs. Pfile
从直观上看，Oracle Restart启动的时候是希望访问到参数文件pfile。从直观的感觉上，好像被替代很长时间的pfile为什么会被提及。利用已经启动的数据库实例，看一下当前使用的是什么参数文件。
SQL> show parameter spfile
