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
