How to Get Started with DAT
The first step is to take a dump of the system that failed, using the
DUMP utility. Once the dump tape is created, it must be copied to a disk
file using DAT.
1. Run the Dump Analysis Tool program.
:DAT
2. Create the dump disk file.
$nmdat > GETDUMP examp
The above command creates the dump file EXAMP. A request appears
on the system console to mount the dump tape.
* Open the dump.
$nmdat > opendump examp
The OPENDUMP command opens the specified dump.
* Analyze the dump.
If the dump was opened successfully, any of the DAT commands are
available to analyze it. The job of dump analysis is greatly
simplified if the DAT macros are used (see the next section for
examples).
When finished with a dump, the user may either exit DAT or open
another dump.
Dumps remain in the system until explicitly purged using the
PURGEDUMP command.
