ORA-01078: failure in processing system parameters
LRM-00109: could not open parameter file '/oracle/app/oracle/product/11.2.0/db_1/dbs/initicare1.ora '
原来打不开initicare1.ora，于是进入/oracle/app/oracle/product/11.2.0/db_1/dbs/目录，
[oracle@datatest ~]$ cd /oracle/app/oracle/product/11.1.0/db_1/dbs/
[oracle@datatest dbs]$ ls
hc_orcl.dat init.ora lkORCL orapworcl spfileorcl.ora
原来是没有initicare1.ora文件
解决此问题的方法就是到cd /oracle/app/oracle/admin/orcl/pfile/目录下，将ora.1114201016265复制到dbs目录下：
cp init.ora.4202014111350 /u01/app/oracle/product/11.2.0/db_1/initicare1.ora
注：在复制时有可能会遇到授权问题 用chmod命令： chmod -R 777 目标 /目标文件夹
然后再次用sqlplus连接数据库
[oracle@datatest dbs]$ sqlplus "/as sysdba"
