Home -> Community -> Usenet -> c.d.o.server -> Re: How to determine which is the master node in RAC cluster?
Hello,
You are correct there is something like a master node. The role of the master node is basicly that this is the node where other "clients"/nodes will contact to get information about node status... ect.
The rule is like this.
-> the first node in a cluster to be up will become the master node.
-> and/or the node with the lowest number will become the master node.
Information about who is the master can be found in the cssd logfile. Check for reconfiguration information at the end of the reconfiguration (completion) you will see which node is the master and how many nodes are active in the cluster.
Hope this helps.
Greetings,
BCB
