As input the DAT program accepts a snapshot dump generated
by the DUMP utility. For output, DAT reads the dump tape into one
or more disk files, called the dump file set.
GETDUMP is the DAT command that reads the DUMP utility
tape into the dump file set so that the information can be analyzed
interactively.
DAT commands allow the user to display data in the main memory
dump as well as secondary store data provided by DUMP. The OPENDUMP command opens a dump for analysis; PURGEDUMP deletes a dump.
Physical, secondary, and virtual addressing modes are supported.
Physical and secondary addressing can be performed regardless of
the accuracy of the dump contents. However, virtual addressing requires
that certain data structures involved in the address translation
process not be corrupt. Most System Debug symbolic formatting commands and
functions may be used to symbolically format data within a dump.
