HDLM has a utility for collecting HDLM error information (DLMgetras).
By executing this utility, you can simultaneously collect all the information required for analyzing errors: information such as error logs, process-specific-trace information files, trace files, definition files, core files, and libraries. You can use the collected information when you contact your HDLM vendor or maintenance company (if there is a maintenance contract for HDLM).
