PH58223: LOAD BALANCER NOT INVOKING CORRECT USER EXITS WHEN HIGH AVAILABILITY IS REMOVED

APAR status

• Closed as program error.

Error description

• When high availability is removed, the goInOp user exit should
  be invoked.
  
  The goInOp user exit is not invoked when high availability
  is deleted by the user. The goInOp user exit is invoked when
  the executor is stopped, but the goStandby user exit is
  invoked after goInOp.

Problem summary

• ****************************************************************
  * USERS AFFECTED:  IBM WebSphere Load Balancer users with      *
  *                  high availability and go scripts            *
  ****************************************************************
  * PROBLEM DESCRIPTION: With high availability and go           *
  *                      scripts, goStandby is invoked when      *
  *                      the executor is stopped. No scripts     *
  *                      run when HA is removed.                 *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  The Load Balancer allows users to write custom actions that
  occur with high availability state changes. These custom
  scripts are referred to as go scripts because of the required
  naming convention: goActive, goStandby, goInOp. The goActive
  script is invoked when high availability enters the active
  state; the goStandby script is invoked when high availability
  enters the standby state. The goInOp script is invoked when
  high availability is removed or stopped.
  The Load Balancer software is not calling goInOp when a user
  issues the "highavailability backup delete" command. When high
  availability is stopped because the executor is stopped, the
  goInOp script is invoked but shortly afterwards the goStandby
  script is invoked.
  

Problem conclusion

• Corrected code not to call goStandby after goInOp when the
  executor is stopped; added invocation of goInOp when high
  availability is removed using the "highavailability backup
  delete" command.
