You have the latest version of SAProuter available on SAP Service Marketplace (see Installing the SAProuter), and have read the README file.
Install the programs SAPROUTER and NIPING in a separate library (such as SAPROUTER).
Log on to the IBM i machine as <SID>ADM.
Create a library
CRTLIB <library name>
Create the backup file SAPROUTER:
CRTSAVF <library name>/SAPROUTER
Create the backup file NIPING:
using the command <library name>/NIPING
Download the programs SAPROUTER.SVF and NIPING.SVF from the SAP Service Marketplace to your local PC, using the following commands:
ftp <IBM i>
cd QGPL
lcd <dir> (<dir> is the directory where SAPROUTER.SVF and NIPING.SVF are located)
bin:
put SAPROUTER.SVF SAPROUTER
put NIPING.SVF NIPING
quit
Re-create the SAPROUTER or NIPING objects. Use the command APYR3FIX as described in SAP Note 493654, and for parameter KRNLIB use the library that you created above.
Create the directory /usr/sap/saprouter.
You have to maintain the Route Permission Table in /usr/sap/saprouter/saprouttab.
