ORA-00439: feature not enabled: Real Application Clusters

还原spfile后启动到nomount

SQL> startup nomount

ORA-00439: feature not enabled: Real Application Clusters

SQL>

这是由于主库集群参数

SQL> show parameter cluster_database

NAME TYPE VALUE

------------------------------------ --------------------------------- ------------------------------

cluster_database boolean TRUE

cluster_database_instances integer 1

SQL>

查看参数特性

SQL> select name,issys_modifiable from v$parameter where name = 'cluster_database';

NAME ISSYS_MODIFIABLE

------------------------------------------- -------------------------------------

cluster_database FALSE

我就直接创建了个pfile把那一行删除了
