Connecting to a logon group
About this task
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/tcpSID 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
