Hi Martin,that's interesting. Normally you have a 1:1 mapping between threads and instances. The mapping of thread to instance usually happens in the initialisation file (spfile), where you find something like
instance_n.thread=n i.e. prod1.thread=1 prod2.thread=2 ... prod7.thread=7In a seven node cluster I wouldn't expect more than 7 public threads, unless there were even more nodes in the cluster which haven't been deconfigured properly. What's the output of this query?
select thread#,status,enabled,instance from v$thread; Best regards, Martin On 08/09/2010 18:48, Martin Brown wrote:
Hello, I am looking around in a new install and I've noticed that the install seems to have created too many threads and corresponding redo logs. We use a 7-node cluster and I see 13 public threads. Is this normal? Any ideas where to look to see what caused it if it isn't? TIA
