With SAPPHIRENOW + ASUG almost upon us, I wanted to introduce a new tool we’ve developed to help you “visualize” social media conversations. We’ve dubbed this a “Conversation Heat Map” and the concept is quite simple: By mashing up Twitter + Google Maps, you can view tweets in real-time from people around the world. In this first iteration, we’ve decided to focus on tweets related to SAP HANA because it’s such a hot topic with lots of interesting conversation.

Check out this link to see it in action. Would love to get your thoughts and feedback!

    Thank u For sharing this unique article. Definitely a life saver.

    this is the situation:
    – <a href=””>SAP S/4 Hana</a> 1.0 SPS12
    – There is no PRELOAD flag set for any table
    – 3TB of column tables are loaded during normal workload
    – The RELOAD feature is active.
    During a HANA revision update (after the executables were updated) the delivery units are going to be imported. If the parameter “reload_tables = true” was set before the update process gets started, the system will reload all tables (3TB) which were loaded during normal operation and recognised by the reload-mechanism.
    Due to the high I/O load, the delivery unit import will be extremly slow and will just complete after the table reload has finished.
    My idea was to set the reload_tables parameter to “false” before the update begins, then do the update and set the parameter back to “true” afterwards in combination with a HANA restart.
    Does the HANA system lose the information which tables were loaded, when I set the parameter to “false” or are they saved somewhere and will be noticed when I re-activate the parameter?
    My fear is, that the information is lost and when I reactivate the parameter the system will rescan all loaded tables at this moment (which are just a few) and so all the other tables needed by the SAP system for normal work don’t get loaded at startup time.
    If the information gets lost: Is there a way to manually save the information which tables are loaded at the moment and to restore this information to the system after the parameter gets activated again?
    Excellent tutorials – very easy to understand with all the details. I hope you will continue to provide more such tutorials.
