Error description
When RunAs EJBROLE is used in WebSphere V5.0 and the application
is driven using LoadRunner to drive n transactions/sec to
create a multithreaded run the authentication fails with the
following symptoms,
.
BBOO0220E CNTR0019E: Non-application exception occurred while
processing  method "app_method". Exception data:
com.ibm.websphere.csi.CSIException:
.
For example in the trade3 application,
SECJ0053E: Authorization failed for "deamon ip address"/"access
ID" while invoking (Home)Trade create:2 securityName:
"deamon ip address"/"access ID";accessID: user "deamon ip
address"/"access id" is not granted any of the required roles
(trade3role,.)
.
at com.ibm.ws.security.core.SecurityCollaborator.
performAuthorization
at com.ibm.ws.security.core.EJSSecurityCollaborator.preInvoke
.
This authentication is successful in a single run of the
application, only a multiple attempt to run the app within a
short period of time or using a tool like LoadRunner would
result in a failure.
