Sybase (SAP) DBA or SAP (Sybase) DBA Cockpit?

Sybase has been in SAP hands for almost 5 years now.  What did it mean to Sybase DBAs?  Did we (if I may reference myself) experience any difference?  Do we feel better or worse?  Did it make any difference at all for Sybase DBA community in general? In my opinion, 5 years is a sufficient period […]
