MaxDB has a long history, not only in development but also in the support of 64-bit platforms.

Contrary to some recent internet articles that suggested MaxDB is starting with 64-bit with MaxDB 7.6, the database structures were first adopted to 64-bit requirements in early 1996 to support the DEC OSF/1 platform. This was ADABAS D Version 6.1.15, at that time still owned by Software AG but already working with SAP R/3.

Subsequently, MaxDB development began to support the major upcoming 64-bit architectures along with their market perception. Since 1997/1998 IBM AIX, HP UX, Sun Solaris, and FSC Reliant were supported, starting with SAP DB 6.2.10…

With SAP DB 7.4.02 the next platform joined the club: Windows (NT) on the IA64 Itanium architecture. This was in 2001. Together with the impressive spread of Linux, Linux on IA64 was supported in 2002 with SAP DB 7.4.03. Within the same release, the first efforts were made for porting to HP-UX/IA64 and the first pilot just rececently received his liveCache for this platform…

MaxDB 7.5, now renamed as part of the MySQL/SAP cooperation, has the most actual ports: Linux on PowerPC (IBM) and Linux on AMD Opteron, both 64-bit. At the end of the current list are MaxDB on Windows/Opteron (AMD) and Windows/Nocona (Intel), which will become available with MaxDB 7.6 scheduled for late 2004.

The hybrid companion of MaxDB, liveCache, in its early stages was bound to Windows 32-bit I386 architectures. But the market demands for performance in supply chain management soon led to the fact that only 64-bit architectures were capable of that load. Thus on Unix, liveCache supports only 64-bit architectures; along with version 7.4.02, Windows (NT) IA64 was shipped too…

Next to come in the liveCache arena will be HP-UX/IA 64 with version 7.4.03 as the base for SCM 4.0, and version 7.5 as the base for SCM 4.1. Linux on 64-bit IBM PowerPC is expected later in version 7.5 for SCM 4.1.

Summing up, this just shows that MaxDB development has always been aware of the 64-bit landscape and has been experienced with the challenges of these architectures for nearly 10 years.
