Cause

IBM Sterling Selling and Fulfillment Suite JVMs cannot communicate with other active IBM Sterling JVMs using RMI calls

Diagnosing The Problem

Use OS tools like lsof / netstat to check the port which IBM Sterling JVMs listen to.

It most likely that port is not accessible from other servers (due to firewall or similar softwares).

Resolving The Problem

Following solution will help if error logs contains error stack as shown in this document.

IBM Sterling Selling and Fulfillment Suite JVMs makes RMI calls to broadcast messages in the events like DB Cache Refresh, Modify Trace levels etc..

If firewall is configured to open specific ports for communication purposes; then IBM Sterling processes must be configured to listen specific ports. This can be achieved using property rmi.portrange . Refer yfs.properties or Properties Guide for more details.

Example :

Following entry in customer_override.properties will ensure that Sterling JVMs will listen on one of the available port between 40000-50000.

yfs.rmi.portrange=40000-50000
