During installation, the SiteMinder Policy Server host was entered incorrectly, or it needs to be changed to point to a different Policy Server.
You can manually update the correct policy server host in the ra.xml file. There is no need to repeat the installation.
The ra.xml file is located in the deployed iam_im.ear file in
../<deployed iam_im.ear location>/iam_im.ear/policyserver.rar/META-INF /ra.xml
Stop the IM application server, edit the ra.xml "ConnectionURL" property, and replace the existing policy server name. e.g. localhost, with the correct host.
<config-property>
<config-property-name>ConnectionURL</config-property-name>
<config-property-type>java.lang.String</config-property-type>
<config-property-value>localhost,44441,44442,44443</config-property-value>
Save the change, delete cached deployment files (like in /tmp, for JBoss, for example), and restart the application server.
