If you want to establish a Java option system property for infogix.uniqueServerName that will be distinct for each running jvm.
Under WildFly you can modify appserver.properties,
property WILDFLY_JAVA_OPTIONS and add -Dinfogix.uniqueServerName=%WILDFLY_NODEID%
%WILDFLY_NODEID% is a Microsoft Windows environment variable reference;
Please add the appropriate dollar-sign-curly-brace thing for Linux.
If you look at a generated start<cfgname>.bat file in wildfly/bin or wildfly2/bin.
you can see that the generated script has an environment variable WILDFLY_NODEID
that is <hostname>-<port> of the cluster node's JVM.
Which yields distinct values for the file names used for logging.
For WebSphere,appserver.properties will contain properties like
JAVA_OPTIONS.1 and WEBSPHERE_APP_TARGET.JAVA_OPTIONS.2, with default values
to pull corresponding product-level JVM options from IA.properties
as an example.Modify these (either up in appserver.properties or
down in IA.properties if you want) to include the additional
system property with a value that makes them unique for log file production.
If this doesn't work, please raise a support ticket and our team will help you troubleshoot the issue.
