更新的具体步骤

Please do the following to renew your SNC credentials:                                           

1. On your SAProuter, delete your existing PSE file and old certificate files ( "cred_v2", "local.pse", "srcert" and "certreq").

2. Generate a PSE (preferred option):

 a) You must provide a password, which will be used to create your SAProuter PSE;

https://launchpad.support.sap.com/#/saproutercertificate

input PSE password

b) Download the generated pse, extract it and then rename it as "local.pse" in the same directory as the sapgenpse executable.

3. Now you will have to create the credentials for the SAProuter with the same program (if you omit -O <user_for_SAProuter>, the credentials are created for the logged in user account):

sapgenpse seclogin -p local.pse -x <pse password>

saprouter://saprouter # ./sapgenpse seclogin -p local.pse -x <pse password>

 running seclogin with USER="root"

 Added SSO-credentials for PSE "/saprouter/local.pse"

It will generate file cred_v2

Then to restart the saprouter:

saprouter://saprouter # ./saprouter -r -V 2 -K "p:CN=<router entry>, OU=<client number>, OU=SAProuter, O=SAP, C=DE"

trcfile  dev_rout
