    ****************************************************************
    On AIX, the LB_PROMISCOUS value set within lbexecutor.AIX is
    lost after a Fixpack update.
    

Problem conclusion

  • ULB has implemented a change to lbexecutor.AIX.  It still
    has
    a default value, but if you wish to have a different value
    persisted, the script file looks for an lbexecutor.conf file
    within /opt/IBM/WebSphere/Edge folder.  If found, it will
    use
    the value provided there.
    Example:  LB_PROMISCOUS="1"
    
    This change is targeted for 8.5.5.17 and 9.0.5.2.
