The following topics might help you diagnose problems with the Object request broker (ORB) component.
The object request broker (ORB) service is one of the product run time services. Tracing messages that are sent and received by the ORB is a useful starting point for troubleshooting the ORB service. You can selectively enable or disable tracing of ORB messages for each server in a product installation, and for each application client.
For instructions on how to set trace controls so that tracing occurs for the ORB subcomponent, read the topic on setting trace controls for IBM® support.
The JAR file that contains these APIs is app_server_root/java/lib/tools.jar.
The ORB service requires a number of ORB properties for correct operation. It is not necessary for most users to modify these properties, and only the system administrator should modify them when required. Consult IBM Support personnel for assistance. The properties reside in the properties file, located at app_server_root/properties/orb.properties.
If none of these steps fixes your problem, check the Support page to see if the problem has been identified and documented. The Support page contains hints and tips, technotes, and descriptions of available fixes.
Before opening a problem report, collect the information that Support needs to resolve problems. The topic on help with troubleshooting includes documents and tools that can help you gather this information.
