ORA-01078 & LRM-00109

今天在启动数据库时出现了如下问题

错误信息：
SQL> startup
ORA-01078: failure in processing system parameters
LRM-00109: could not open parameter file '/opt/oracle/products/10.1.0.3/db_1/dbs/initjason.ora'

注：Oracle在启动过程中,需要读取参数文件(pfile/spfile)来创建实例.Oracle在启动过程中,寻找参数文件的顺序为:spfile.ora,spfile.ora,init.ora.
