Re: [Networker] too long to allocating channel for rman backup

Thank Mattew,

On the oracle server ,there are two nsrexecd processes.
I also installed networker client, NMO 4.2 on the oracle server.
I think maybe the problem is DNS.
Oracle server joins in DNS, Networker server doesnot.
Oracle server is a RAC system. I only backup on one node (i shuttdown 
the other)
On this node, there are two network cards
1st card has: boot address, 2 oracle vip addresses,1 hearbeat address
2nd card has: oracle crs interconnect address
Do i need to declare all these addresses on the hosts file of networker server?
