Error description

• On the JSESSIONID a delimiter is used to parse the session ID
  from the Application Server ID.  This delimiter is set and
  returned from the Application Server to the ODR for session
  routing.
  
  By default this is set to colon (:) in the application server.
  However, the Application Server session management or
  webcontainer (deprecated in 7.0) properties CloneSeparatorChange
  and CloneSeparator can be used to change the delimiter to
  another character.  Most commonly if changed this will be set to
  plus sign (+) however, this does not have to be the case.
  
  Since the delimiter is returned from the application server and
  the ODR can route to multiple application servers there is no
  guarantee that each application server will use the same
  delimiter.  However, currently the ODR can only read a single
  delimiter.  This means that the ODR could fail to route to
  application servers which are not using the same delimiter that
  the ODR is using.  This can be seen in the ODR trace as the
  example below:
  
  [1/5/12 12:17:19:928 EST] 0000001c XDDWLMClientS 3   delimiter
  ':' not
  found in session ID '1111j4KdU1111DCtec_MuEiujK_+16mkl87y6'
  
  This shows a response from an application server which is using
  a separator of '+' however, the ODR is looking for a delimiter
  of ':'
  

Local fix

• Set all the CloneSeparators in the application servers to the
  same value and use this value in the ODR.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED:  All users of WebSphere Virtual Enterprise   *
  *                  that                                        *
  *                  have configured a web container to use non- *
  *                  default clone id separators.                *
  ****************************************************************
  * PROBLEM DESCRIPTION: The On Demand Router does not properly  *
  *                      handle non-default clone id             *
  *                      separators.                             *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  The On Demand Router does not properly handle clone id
  separators
  when web container custom property CloneSeparatorChange has been
  set to true.
  

Problem conclusion

• Support for the CloneSeparatorChange web customer property has
  been added to the On Demand Configuration component. Please note
  that PM55852 is also needed before the On Demand Router will
  properly handle the CloneSeparatorChange web customer property.
