问题描述：rac环境节点1修改参数后，节点2启动出现ORA-01105、ORA-01677告警，如下所示：
环境：oracle rac(双节点) 11.2.0.4 此为双节点rac dg环境
1、问题重现
--节点2启动报错

2、问题排查
--查节点1参数

3、解决过程
--节点2执行
SQL> create pfile='/home/oracle/pfile.ora' from spfile;

File created.
[oracle@hisdb2 ~]$ vi pfile.ora
添加如下内容：
*.db_file_name_convert='+data/healdg/datafile/','+data/heal/datafile/','+data/healdg/tempfile/','+data/heal/tempfile/'
*.log_file_name_convert='+data/healdg/tempfile/','+data/heal/tempfile/','+data/healdg/onlinelog/','+data/heal/onlinelog/','+data/healdg/controlfile/','+data/heal/controlfile/'
*.fal_server='healdg'
*.fal_client='heal'
