Knowledge modules

A knowledge module is an executable load module that Transaction Analysis Workbench uses to interpret and process a particular type of log record.

Transaction Analysis Workbench is supplied with many knowledge modules. Each knowledge module contains the following information, sometimes referred to as metadata, about a particular type of log record:

• Field structure, data types, and names. Field names in knowledge modules typically match the names in the IBM-supplied z/OS® assembler data sections (DSECTs) that map each record type.
• Field descriptions. Transaction Analysis Workbench displays these descriptions when you zoom on a field while browsing logs in the ISPF dialog.
• Which fields in the record type map to Transaction Analysis Workbench global fields.

You can create your own knowledge modules for IMS log records written by IMS applications, known as IMS user log records, enabling you to analyze these log records in exactly the same way as log records written by IMS itself.
