RAC环境在修改参数后，重启一个节点遇到ORA-01105和ORA-01677错误。数据库版本11.2.0.4。具体操作如下，以下操作在节点1。

SQL> alter system set db_file_name_convert='+DATA/erpdb/datafile/','/u01/app/oracle/oradata/erpdb/','+DATA/erpdb/tempfile/','/u01/app/oracle/oradata/erpdb/' scope=spfile sid='*';

System altered.

SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.

SQL> startup
ORACLE instance started.

ORA-01105: mount is incompatible with mounts by other instances
ORA-01677: standby file name convert parameters differ from other instance

这是因为节点1重启后，新修改的参数已经生效，而节点2此时没有重启，使用的还是旧的参数，两边不一致。关闭或重启节点2，节点1可以成功启动。
