存在Oracle19c Rac数据库，共享存储使用ASM，以及Oracle19c单实例，数据文件为文件系统，在Rac环境通过PDB克隆或者Relocate单实例数据库时总是报错，无论指定CREATE_FILE_DEST、FILE_NAME_CONVERT 、PATH_PREFIX 、DB_CREATE_FILE_DEST 、PDB_FILE_NAME_CONVERT都无法实现将单实例的PDB克隆或者Relocate到Rac集群环境，但是若是两个都是单实例（存储都是文件系统）时正常，是在12c中不支持单实例至Rac此功能吗。

Rac发出Relocate命令
SQL> CREATE PLUGGABLE DATABASE cwsavpd FROM sapdb@DBLINK_CDB_ORCL RELOCATE PATH_PREFIX = ‘+DATA01’;
CREATE PLUGGABLE DATABASE cwsavpd FROM sapdb@DBLINK_CDB_ORCL RELOCATE PATH_PREFIX = ‘+DATA01’
