Problem summary

  • ****************************************************************
    * USERS AFFECTED:  IBM HTTP Server users on z/OS with          *
    *                  rotatelogs configured                       *
    ****************************************************************
    * PROBLEM DESCRIPTION: rotatelogs on z/OS is using an extra    *
    *                      address space per instance              *
    ****************************************************************
    * RECOMMENDATION:  Apply this fix if using rotatelogs for IBM  *
    *                  HTTP Server on z/OS                         *
    ****************************************************************
    On z/OS, rotatelogs had to be launched by a /bin/sh wrapper
    which used an additional address space.
    

Problem conclusion

  • rotatelogs can now be launched without being wrapped by
    /bin/sh which saves an address space per piped logger instance.
    This global behavior is activated by the native environment
    variable IHS_PIPED_LOGGER_NO_SHELL being set to any value.
    
    Without the new native environment variable
    IHS_PIPED_LOGGER_NO_SHELL, SIGTERM is not sent to rotatelogs.
    With IHS_PIPED_LOGGER_NO_SHELL, SIGTERM will be seen during
    shutdown and trigger a warning: CEE5205S.
    A new -T flag for rotatelogs has been added to ignore SIGTERM.
    
    This fix is targeted for IBM HTTP Server fix packs:
    - 7.0.0.43
    - 8.0.0.13
    - 8.5.5.10
