PI20340: ODR AFFINITY LOGIC FAILS AND IS UNABLE TO ROUTE THE REQUEST TO THE CORRECT APPLICATION SERVER

APAR status

• Closed as program error.

Error description

• When a request arrives, it's initially classified based on
  its URI pattern alone, the affinity logic has not yet run.
  Later, the ODR runs the affinity logic, and it identifies the
  proper destination based on the clone ID present in the session
  cookie.  However, due to a bug in the code, the ODR does not
  switch to the affinity destination.

Problem summary

• ****************************************************************
  * USERS AFFECTED:  All users of WebSphere Virtual Enterprise   *
  *                  who have multiple editions of an            *
  *                  application in which the application root   *
  *                  is not the same as the module root.         *
  *                  Application root refers to the name of the  *
  *                  installed application and module roots      *
  *                  refer to the context roots of different     *
  *                  web modules in the application here.        *
  ****************************************************************
  * PROBLEM DESCRIPTION: When an affined request is sent to      *
  *                      the On Demand Router(ODR), the ODR may  *
  *                      not send the request to the affined     *
  *                      destination.                            *
  *                      Let's suppose a request is sent to      *
  *                      edition A of an application and         *
  *                      affinity is established. Now when       *
  *                      edition B is rolled out, and the        *
  *                      second request is sent with affinity,   *
  *                      the request does not reach the          *
  *                      destination to which the affinity was   *
  *                      established.                            *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  There is a bug in the selection of the right affinity
  destination.
  

Problem conclusion

• The code has been fixed to choose the right destination now.
  
  This issue will be resolved in the next available fix pack for
  WebSphere Virtual Enterprise V7.0 and V.8.5.5.
