The allocation is successful. However, the file of the Backup set cannot be created on channel c3. Because I performed RMAN backup on node 1. At first, we thought that all the backup files would be stored on node 1. Therefore, only the backup directory is created on node 1. That is, the/u01/backup directory. Node 2 is not created. This is where the problem occurs. After I created the/u01/backup directory on node 2 and granted the 777 permission, the backup was successful. Check the two backup files. The backup set file of orcl1 channel is stored in the backup Directory of Node 1 (/u01/backup ), the backup files of the orcl2 channel are stored in the backup Directory of orcl2 (/u01/backup ). because its backup files are stored in two places, it will be very troublesome to restore. The ideal status is that all backup files are stored on one node or shared device. -- This article
