What to do my SAProuter does not run

If your SAProuter does not run do the following steps.
1. Create the subdirectory SAProuter in the directory /usr/sap/.

2. Download the latest version from sapserv3, directory /general/misc/saprouter. Also see the corresponding file 'README' in this directory. Copy programs 'saprouter' and 'niping' into the directory /usr/sap/saprouter.
    If you cannot copy the programs from sapserv3, you can get a (possibly out-of-date) version from the directory /usr/sap/<SID>/SYS/exe/run.

3. Add the following lines to the file /users/<SID>adm/startsap_<host name>_<instance number> before the lines '#Start OS-Collector daemon'.

    # # Start saprouter
    #
    SRDIR=/usr/sap/saprouter
    if [ -f $SRDIR/saprouter ];then
       echo "nStarting saprouter Daemon " | tee -a $LOGFILE
       echo "--------------------------- " | tee -a $LOGFILE
       $SRDIR/saprouter -r -W 30000 -R $SRDIR/saprouttab
                      | tee -a $LOGFILE &
    fi
    This entry automatically starts the SAProuter during the system start and it ensures that the SAProuter is always started. Since the SAProuter should continue to run after R/3 is shut down no respective entry is included in the Stopsap Script. If you boot the R/3 several times, the system displays error messages when the SAProuter is started. You can ignore these error messages. The entry of the SAProuter in the Startup Script is a recommendation. However, you can also start the SAProuter manually.

4. The corresponding routing table must be maintained in /usr/sap/saprouter/saprouttab.

5. Remarks

As of version 25 the SAProuter must have a routing table. The router terminates with an error message if it cannot read the table. If you do not want an authorization check use the line 'P * * *'.
