We have two SPARC T4-2 servers and ZFS 7120 storage with Fibre Channel connectivity. Our objective is to run Oracle RAC with half the number of cores that are available on T4-2 server. We won't be using the remaining cores. We will be using Oracle VM Server for SPARC also known as LDOMs for virtualization.
We would like to just reconfigure the primary domain with half the number of cores and install Oracle RAC software. I understand that it is a good practice to run Oracle RAC in root domain by dedicating entire PCIe root complex to the domain but some of my colleagues think it will be difficult to manage the environment by end user. Is it a good practice to run Oracle RAC 18.104.22.168.0 in OVM Server for SPARC Control Domain instead of root/IO/guest domains? I would like to install it in root domain as it is according to Oracle best practise.
