[jira] Updated: (ODE-484) Implicit Correlations i.e. Magic
session(soap header filled with session information,not p2p mode) failed
when ODE heavily loaded
[ https://issues.apache.org/jira/browse/ODE-484?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Shammy Chen updated ODE-484:
----------------------------
If you can debug ODE in eclipse or sothing else,you will find class org.apache.ode.axis2.SoapExternalService is the source of this problem.Just set a breakpoint at line 273,just before the following statement:
options.setProperty("callbackSessionEndpoint", odeMex.getMyRoleEndpointReference());
When two client come at the same time,variable myRoleEPR of writeHeader method is the same,that is,they have the same reference.We can't control the execution sequence of two thread,so we can't tell what will happen when concurrently executing the following statement:
myRoleEPR.setSessionId(myRoleSessionId);

> We use tempo and ODE to deal with human tasks,but when the system is heavily loaded,sothing goes wrong.The following is adapted from the error log:
