Unanswered: Migration Grid 11Gr2 & scan address : round-robin DNS or GNS ?
We're installing a 11gr2 Grid environment... using the new scan addresses.
We'll have 3 nodes in this grid.
Telecom' engineers are reluctant to implement round robin in their DNS.
The other solution is using DHCP & GNS but it's a more complex architecture.
If you're using RAC & grid 11gr2
1) did you implement DNS round robin ?
2) did you implement GNS... ?
3) did you use hosts files ?
4) how many nodes are including in your grid ?
Thanks four your feedback
