             Summary: LP Bug: 1331349 - The throughput doesn't increase  if multiple mxosrvrs are connected
                 Key: TRAFODION-387
                 URL: https://issues.apache.org/jira/browse/TRAFODION-387
             Project: Apache Trafodion
          Issue Type: Bug
          Components: connectivity-dcs
            Reporter: Jian Jin
            Assignee: Daniel Lu
            Priority: Critical
             Fix For: 0.9 (pre-incubation)


IceWall’s regression was runing against Trafodion workstation instance with 16 DCS servers. Throughput was 550 hits/second. Surprisingly if  only 1 DCS server is opened, the throughput remains same. We tried changing all sorts of IceWall configuration but it didn’t help. It was  suggested that somehow Trafodion makes only 1 connection available for IceWall’s regression tool and rest of the connections are not used. Changing IceWall configuration to use more DB connections should increase throughput but it remains same.   After investigation it was confirmed that all configured connections are used. 

It doesn't seem to be a DCS/mxosrver issue but still need to check why the  throughput doesn’t increase if mxosrvrs are doubled.
