oracle启动异常解决…

错误

SQL> startup ORA-01078: failure in processing system parameters
LRM-00109: could not open parameter file '/u01/app/oracle/product/11.2.0/db_1/dbs/initsznfpt.ora

启动的参数文件丢失

解决

1.进入sid保留的init
echo $ORACLE_SID  //查看当前sid

cd $ORACLE_BASE/admin/<sid>/pfile  
    init.ora.1131201617420   ---->  init<sid>.ora

2.复制init<sid>.ora到dbs/pfile中
/u01/app/oracle/product/11.2.0/db_1/dbs/pfile/  
　　initsznfpt.ora

3.启动数据库实例
sqlplus / as sysdba;
SQL> startup
ORACLE instance started.
