ORA-01078: failure in processing system parameters(oracle 11g for Asianux3 ORA-01078 and LRM-00109 )

故障现象：ORA-01078: failure in processing system parameters
LRM-00109: could not open parameter file '/array/ora/oracle/product/11.2.0/db_1/dbs/initorc1.ora'

原理：在oracle9i和oracle10g中，数据库默认将使用spfile启动数据库，如果spfile不存在，则就会出现上述错误。
 解决办法：将$ORACLE_BASE/admin/数据库名称/pfile目录下的init.ora.012009233838形式的文件copy到$ORACLE_HOME/dbs目录下initoracle.ora即可。（注：initoracle.ora中的oracle为你的实例名 ORACLE_SID）

故障：
[root@db2 ~]# su - oracle
-bash: /home/oracle: is a directory
-bash: /home/oracle: is a directory
-bash: /home/oracle: is a directory
[oracle@db2 ~]$ sqlplus "/as sysdba"
