title: Connection Pools Size vs. Number of concurrent requests
body: <p>I have to develop a high scalable webservice, but the connection pool size (Oracle DB) is set to 50.</p>
  
  <p>Having this size means that the number of concurrent request served will be max 50 ,otherwise the no new connections will be available right ?</p>
  
  <p>But by configuration is possible for the Weblogic or Glassfish server to accept more then 50 requests simultaneously ?</p>
  
  <p>I read that the server accepts the request which are 'queued' until a thread is handling them.</p>
  
  <p>Regarding 'scalability' I have a question mark as well because the average DB calls take 1,2 sec. + the soap overhead...==> in a 2,3 sec response time on each call.</p>
  
  <p>Can I estimate how many concurrent users the server will support (Weblogic or Glasfish 4gb) ?</p>
  
  <p>Thank you</p>
