Customer want to install netbackup Agent directly on Db server Nodes on Exadata,from netbackup respective both OS version and DB version are supported however i'm reluctant to install directly any agent on Db homes,which will include relinking rman binaries to netbackup agent

the second part that netbackup does not support usage of scan name instead a connection to each db node is required via vip.

I could not find a document from exadata point of view to install netbackup Agent directly,is there any notes/best practices installing netbackup on exadata?.
