Problem summary

• ****************************************************************
  * USERS AFFECTED:  IBM WebSphere Application Server Load       *
  *                  Balancer users                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: When the goStandby script is            *
  *                      configured, it will be executed more    *
  *                      than once when the Load Balancer is     *
  *                      in the standby state.                   *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  The load balancer allows users to configure 'go' scripts such
  that the script is invoked when the load balancer changes high
  availability states.  The goStandby script will be invoked
  more than once when the load balancer is in standby mode.
  

Problem conclusion

• The load balancer code which invokes the go scripts did not
  define the high availability states in the same manner as the
  code which detects state changes.  When the load balancer is
  in standby mode, the code which invokes the go scripts may
  falsely detect a state change because of the different state
  definitions.  Code has been corrected to define the states
  consistently in the load balancer code.
