我需要解决方案
We have a 4 node Exadata system. The Oracle admins have created a DBFS (DataBase File System) that is shared among the nodes. They want to back this up. We were originally able to back it up, but only on the node that was used to create the file system. That node was rebooted last week, and now we are not able to back it up at all. The Oracle admin is fairly certain that it has something to do with how the file system is mounted, but he is not sure what to change. Does anyone have any experience with backing up a DBFS file system on an Exadata platform?
