sun E4900 problem

hello everyone,

Our company is using a sun E4900 cluster. Last day, all instances of Oracle database has been suddenly stopped whitout treggring any alarm for a 15 minutes and has started alone without any action from the DBA.

Can anyone explain me what's the origin of this problem ?

Thanks

no... not without a lot of further investigation... but i assume there was a cluster failover (which would explain the 15 min downtime). but to know the rootcause needs more digging.

Thanks for your answer. We don't have the same instance of Oracle on th two nodes.We have like 11 instances on the node 1 and 2 instances on the node 0. Only the instances of the node 1 have been stopped. can you now explain me what happened exactly?

thanks a lot

Our system is a sun cluster composed of two servers sun E4900.Both servers are running under solaris 9 and we have Oracle installed on it.

could be 1000 things... open a call at oracle and give them the needed data (they will ask for it). or hire a consultant to help you out with your problem...

I have already send the core files to Oracle support. Can you give me examples of what could be the problem ?
