Last updated on JANUARY 12, 2017

Applies to:

Oracle Fusion Middleware - Version: 10.1.2.0.2 to 10.1.3.5.0 - Release: AS10gR2 to AS10gR3
Information in this document applies to any platform.

Symptoms

Oracle Application Server 10g cluster consisting of two nodes.

Not able to display status of the remote node with the following command:

ORACLE_HOME/opmn/bin/opmnctl @cluster status

The following errors are observed in the opmn_log on both cluster nodes.

 [ons-connect] Connection x,<remote hostname> connect (Connection refused)

Changes

The command used to configure the two node cluster is:
opmnctl config topology update discover="node2.oracle.com:6200"
opmnctl config topology update discover="node1.oracle.comt:6200"
The rest of this article will assume ONS request port 6200 as an example.
