Hi Can somebody share the experience on the following I had four10g Oracle RAC and each one is 4 Node RAC. Each one have Private network but not Private VLAN 1. Is Sharing same subnet on the same Private VLANs for interconnects of different RAC configurations supported? It is working fine currently and so it is working but want to check expert advice if this is good recommendation ? 2. Will that cause any performance hit? That means the Interconnect IPs of One RAC configuration is pingable from other RAC configuration. I found few times that CRSD daemon is not responding in one environment and so is it possible due to sharing Same subnet of Private VLAN? TIA Sanjay
