AS Instances on Separate Nodes in a Static Discovery Server Cluster Cannot See Each Other (Doc ID 459076.1)

Last updated on SEPTEMBER 06, 2016

Applies to:

Oracle Fusion Middleware HA - FMW HA - Version: 10.1.3.0.0 to 10.1.3.2.0 - Release: AS10gR3 to AS10gR3
Information in this document applies to any platform.

Symptoms

This note addresses a topology consisting of two or more AS instances installed over two or more separate nodes. (The High Availability term 'node' is used in this article to denote a physical server.)

The AS instances have been configured as a Cluster using the Static Discovery Method as outlined in

Oracle´┐Ż Application Server Administrator's Guide
10g Release 3 (10.1.3.1.0)
Part Number B28940-01
6 Reconfiguring Application Server Instances
6.2 Configuring Cluster Topologies

Each AS instance has an entry in opmn.xml similar to this example:

<notification-server interface="ipv4">
<port local="6101" remote="6201" request="6004"/>
<ssl enabled="true" wallet-file="$ORACLE_HOME/opmn/conf/ssl.wlt/default"/>
<topology>
<discover list="hostname.domain:6201"/>
</topology>
</notification-server>

The output from executing '$ORACLE_HOME/opmn/bin/opmnctl @cluster status' from each AS instance only shows details of the AS instances installed on the local node.
It is possible to ping all of the remote servers.

The goal is for the cluster configuration to communicate with all AS instances in the cluster, including those AS instances on remote nodes.
