Connecting to a logon group

In large SAP installations, the application servers are usually configured in logon groups for load balancing and fault-tolerance purposes. Load balancing is done by a dedicated server, called the message server. The message server automatically assigns users to the application server with the least workload of the logon group it controls.

Ensure that the file services (on UNIX: /etc/services on Windows: C:\Windows\system32\drivers\etc\services) contain an entry for the message server port of the SAP system to which r3batch connects. The entry has the following format:
sapmsSID 36system_number/tcp
where SID is the SAP system ID, and system_number is the SAP system number.
Set the following options to configure r3batch to connect to a logon group:
r3host
The hostname of the message server.
r3group
The name of the logon group.
r3sid
The SAP system ID.
For example:
r3host=pwdf0647.wdf.sap-ag.de
r3group=PUBLIC
r3sid=QB6
