4 SAP Supply Chain Management
Within SAP Supply Chain Management (SCM) scenarios two main
technical components have to be distinguished: the APO System and the
liveCache
The first technical component, the APO System is based on SAP WAS
technology. Therefore, (ci), (db), (dbci), (d) and (sapnfs) packages
may be implemented for APO. These APO packages are set up the same
way as the Netweaver packages. The only difference is that the APO
system needs access to liveCache client libraries and database binaries
(e.g. dbmcli...). These files usually are searched via the path
/sapdb/programs.
The second technical SCM component, called liveCache, is an in-memory
database. liveCache is based on MaxDB database technology. SAP has
defined a list of policies and requirements in order to allow support for
liveCache High Availability. Therefore a liveCache Serviceguard
Extension for SAP on Linux package does not use the generic (ci), (db),
(dbci), (d) and (sapnfs) package templates instead a new Serviceguard
Extension for SAP on Linux template called (lc) will be introduced.
This chapter describes how to configure and setup SAP Supply Chain
Management using a failover liveCache.
