The EH&S management server is installed as a
Microsoft Windows serviceand manages the generation servers for the
Windows Wordprocessor Integration
(WWI) program and the EH&S Expert servers for the SAP EH&S component by Remote Function Call (RFC) from the SAP system.
Using the EH&S management server you create the WWI generation servers and EH&S Expert servers as Microsoft Windows services.
Alternatively you can set up WWI generation servers and EH&S Expert servers manually as console programs in Customizing for
Basic Data and Tools
. In contrast to console programs, Microsoft Windows services can last longer than the duration of a session. This means the service can be executed without a user having to be logged on to the PC. A service can, for example, be started automatically at system startup and be run in the background for the user.
Only one EH&S management server can be installed on a server PC, but this server can log itself on to a number of SAP systems. The EH&S management server has the following architecture:
There is one Remote Function Call (RFC) server per SAP system, which technically is a threadand which handles communication with the SAP component EH&S.
Synchronization of the EH&S management server allows it to log on to several SAP systems.
The EH&S management server monitors existing WWI generation servers and EH&S Expert servers and restarts them if errors occur. The Service Control Manager (SCM) serves as the central technical communication instance between two services or between a service and a service administration program.
Within EH&S service administration, the EH&S management server has the following functions:
Installation and deinstallation of services
Control of services (starting, stopping, restarting)
Display and change of service configurations (SAPRFC.INI, WWI.INI, EH&S Expert parameters and EH&S Expert sets of rules)
File transfer
File transfer from server PC to front-end PC
File transfer from front-end PC to server PC
