Hi Andy:
Actually, multiple SIDs (physical DBs) on one production SAP HANA system is available today as part of an "early adopter" program where the customer must work closely with SAP on sizing and other aspects in order to implement. I will discuss the implications for the text of note 1681092 with my colleagues.
However, as mentioned previously in this thread, with SPS09 we plan to introduce a new feature called "Multiple Databases" which will address most of the requirements that cause customers to consider installing more than one physical DB in a more elegant, efficient, and effective manner. Thus the demand for multi-SID will diminish as this becomes available.
That said, there probably will still be some use cases...e.g. with Multi-DB all tenant DBs are on the same revision...thus some customers may want to run Multi-SID anyway. We will figure out the positioning for that in the months ahead as we get ready to roll out Multi-DB.
B/R -
