10. DETAIL NiPGetServByName: sapmsCYB not found

12. COUNTER 1

 

Cause

The server is unable to translate request for symbolic port name into actual port number.

Environment

Release : 12.x

Component : Workload Automation Agent for SAP

Resolution

Add the line like below in /etc/services file;

sapmsCYB 3600/tcp # SAP connection service

where, CYB is the SAP system ID (SID)

The entry causes the server to translate requests for the symbolic port name "sapmsCYB" into the actual port number 3600. This is required to use SAP load balancing.
