Hi Guys, I have a 4 node cluster running RH Cluster Suite 4. I have just added a DB2 service to one of the nodes and have starting gettingerrors relating to locks ion the system log. I plan to restart this node at luch time today to see if this fixes the problem. Is there anyone who can explain what these errors relate to so that I can understand the problem better. I have checked RHN, Cluster Project website and Google and I cant find anything? Its worth mentioning that the service is running fine.
