Issue/Introduction

We're trying to set up new SAP R/3 servers on our environment, but we're coming against an error and need help deciphering it. The previous setup we have does not use a gateway, but this new setup uses one. Please let me know what you think about what is shown below. The directory shown is not in our system (/xxxxxx/krn/si/gw/gwr3cpic.c).  Thanks!

Environment

Release : 12.x

Component: Workload Automation Agent for SAP

Cause

SAP load balancing configuration issue.

Resolution

Configure the Agent SAP plugin to connect with load balancing.

Add the following parameters to the connection properties file.

jco.client.mshost=<SAP message server>
jco.client.group=<SAP group name>
jco.client.r3name=<SAP system ID>

Note: The value for jco.client.group must be a group that has been previously created using the SAPGUI.

Obtain the value of these parameters from your SAP support team and provide them as value. These changes require restart of agent to take effect.
