Overview of Mini-Dump Configuration 

The mini-dump feature allows you to create an ASCII file that is a
summary of a system dump when the system fails.  The mini-dump created is
output from SAT, which summarizes the system failure.  The mini-dump
contains a date and time stamp, the MPE/iX version identification, the
system failure number, and a stack trace.  This information can be used
to track system failures and to notify system managers, through network
transmissions.

The mini-dump feature is especially beneficial for customers with
homogeneous environments (many systems with similar configurations and
operating system versions).

In a homogeneous environment many duplicate problems can occur;
therefore, the mini-dump feature can be used to bypass taking a full
memory dump for system failures that have already occurred.  The
mini-dump can be configured for reoccurring failures.  New problems
cannot be diagnosed; however, if you want to minimize system recovery
time due to repeat failures, then the mini-dump feature is recommended.

The mini-dump is not intended to replace a full memory dump.  A mini-dump
provides a summary of the system failure only.  When a system failure
occurs, a full memory dump is required so that diagnostics can be run.


NOTE  Before proceeding with the mini-dump configuration, become familiar
      with the BLDDUMP commands BUILDMD, INITMD, and LISTMD. These
      commands are described in the "Managing the Dump-to-Disk and
      Mini-Dump Features" later in this chapter.
