CPU spikes
Application server(s) running the Oracle SOA Suite can experience the CPU spikes for one of the following reason(s):
User activity: The sudden peak in the user(s) requests can cause CPU spikes on the application server(s). The key is to understand the user types and their pay load and performance needs. For example, users sending individual real time transaction demands that these transactions are completed in the shortest possible time while batch and cron users won't mind waiting for the transactions to finish successfully. It is a leading practice to build separate platforms for serving real time end users and batch and cron users.
Request queuing: The real spikes in the users' requests can also be caused by the CPU spikes that result in poor performance. You may plan to adjust your system architecture to avoid the queuing of users' requests by adding more application server(s).
Thread count: High thread count setting in a server platform can cause CPU spikes as well. Identify...
