z/OS Communications Server V1R11 is upon us and you probably have not even caught your breath over the major enhancements in z/OS V1R8, V1R9, and V1R10. Did you know there were a lot of hidden gems in these releases and even in V1R8 that could make your life easier? This session presents practical examples of a treasure chest of diamonds, rubies, sapphires, and pearls for your Communications Server z/OS implementation. This knowledge should help you feel somewhat caught up for that next move to z/OS V1R10 or 11. Disclaimer: There are no IPv6 and very few Enterprise Extender or Sysplex/VIPA topics in this presentation, as these two subjects have been on the radar screen for quite a while now and are covered extensively in many other presentations. Therefore, this session tends to focus on subjects that have been 'under the radar' and that have escaped many an implementer's attention.
