System Diagnostics

The System Diagnostics function is used to take a snapshot of various system tables. This is achieved by extracting data from the IBM Z Decision Support system tables. The data is written to a sequential file called tsoprefix.DRLDIAG. If the file has not been allocated, the Systems Diagnostic feature will allocate it when it is executed.

The main purpose of this function is to provide IBM Support personnel with an overview of the components and subcomponents that have been installed. This information can be useful when working on faults. Information about the log data sets that have been collected is also extracted.
