The following is a high level diagram of the SAP ACC Architecture.
Figure 4 Architecture for SAP Adaptive Computing Controller
The ACC station or Control node consists of the WebAS 6.40 J2EE Engine and the Adaptive
Computing Controller software. The ACC software communicates with the System Landscape
Directory (SLD) to derive a list of managed nodes installed in the SAP Landscape. Each managed
node needs to register itself in the SLD Using remote function calls, and the SLD collect status
information from the managed node using the saposcol agent installed on each managed node.
The ACC also requires the SAP instance-specific information from SAP® Solution Manager and
obtains this information using remote function calls via the gateway process. The gateway process
can be implemented either as a standalone or an integrated gateway system.
All Adaptive Computing operations are initiated and controlled from the SAP ACC control node
using the GUI provided by SAP.
An SAP ACC agent is installed on each managed node in the system landscape that is under ACC
control. This “sapacosprep” agent receives command operations from the central SAP ACC
controller and executes the necessary integration modules to enable adaptive computing functions
on the managed node.
Internally the “sapacosprep” agent comprises of a platform/partner independent module and an
API that enables partners to integrate their platform and storage solutions by providing the
