故障现象:ORA-01078: failure in processing system parameters 
 

LRM-00109: could not open parameter file '/u01/app/oracle/product/10.2.0/db_1/dbs/initorcl10g.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:
 
方法一:将$ORACLE_BASE/admin/orcl/pfile目录下的init.ora.0212012125517形式的文件copy到$ORACLE_HOME/dbs目录下initoracl.ora即可。(注:initoracl.ora中的oracl为你的实例名 ORACLE_SID,这里我的SID为:orcl10g)
 
方法二:将$ORACLE_HOME/dbs目录下spflieoracl.ora改名为spfileorcl10g.ora即可。(注:spfileorcl10g.ora中的orcl10g为环境变量中设置的SID,我的是orcl10g)
