The commands provided by DAT presuppose a solid background in MPE XL internals. To help reduce the need for every dump analysis engineer to possess detailed knowledge of MPE XL, a group of dump analysis macros have been developed to assist field and lab support personnel in the task of dump analysis.

This group of macros (MPEXL OS DAT MACROS, HP30357 A) is referred to as "The DAT Macros." An external specification document and quick reference guide is available from HP support organizations. The DAT program, supported macros, (MOS), and symbolic data type files (SYMOS, VAMOS)are distributed in the TELESUP account.

How to Get Started with the DAT Macros

Using the DAT macro package is the simplest way to analyze a dump. Additional documentation is required to make use of the macros. Contact your Response Center for further information.

To use this package, log on to the TELESUP account in the USER group. The TELESUP account is where the DAT program, the macro files, and the symbolic data type files are located. The first step is to start the DAT program and invoke the DAT Macros startup macro. Entering "macstart" loads Macros and symbols.

Examples

Some examples of DAT macros follow. Please note that these macros are dynamic. They will change and be improved. The output from these examples may differ from what future macros produce.

The above examples give a hint of the power and convenience of using the DAT macros package for dump analysis. There are many more macros; they format an operating system table, print process information, display resource allocation, help find deadlocks, and so on.
