Error messages
When an error occurs in a request, messages are always written to the message log data set allocated to the caller address space. The data set is either EQQMLOG or that specified in the MLOGDDN argument of the INIT request. In certain cases, messages are also written to the EQQMLOG data set allocated to the HCL Workload Automation for Z subsystem to which your requests are directed.
Errors related to the request itself (for example, a spelling error in a parameter argument) result in a message written only to the message log allocated to the caller address space.
Errors related to the HCL Workload Automation for Z subsystem (for example, an error detected by HCL Workload Automation for Z data validation) result in a brief message to the caller message log. A more detailed message about the error is written to the EQQMLOG allocated to the HCL Workload Automation for Z subsystem.
