RMF Sysplex Data Server
The RMF Sysplex Data Server is a distributed RMF™ function. It is started as an identical copy on each system of the sysplex. Each copy of the data server communicates with all other copies in the sysplex. RMF uses this sysplex communication method to provide access to distributed RMF measurement data from any point in the sysplex.

Flow. The application program may call the RMF Sysplex Data Services from any point in the
sysplex.
The RMF Sysplex Data Server is always active when the RMF address space is running.
You can access all types of RMF and SMF data collected in the sysplex by
using RMF Sysplex Data Server programming interface services. These
are invoked as callable services by the RMF reporter
sessions themselves or other applications, and can access:
- Monitor I, II and III SMF data
- Monitor III VSAM data
- SMF data of any other type
To call the RMF services for SMF data, you need authorization to access the SMF data.1 For details, please see Controlling access to RMF data for the sysplex data services.
1 Authorization of application programs is provided
by the z/OS Security Server RACF®,
or products with similar functions, that define the user group authorized
to access measurement data returned by the RMF Sysplex Data Server
callable services.
The services may be invoked by programs running under any PSW key and in problem state, like the Postprocessor and Monitor III reporter sessions.
