Offline dump

Using LCDS Print Description Language
The offline tape dump feature is a troubleshooting tool for tape
jobs. It allows you to generate a hardcopy printout of all the
characters, carriage control information, channel status, tape
labels, and other information in the data stream, while a job is
being transmitted and printed.

Starting and ending tape dump sessions

To print a dump of an offline job you wish to troubleshoot, follow
these steps:
1. Specify the DFLT JDE and the DUMP JDL on the Tape Client
window at the controller. (The DUMP JDL, which was loaded
on your system at installation, contains the VOLUME
HOST=DUMP and CODE=EBCDIC commands as well as
the DFLT JDE.)
2. Run the job you intend to troubleshoot.
3. Terminate the dump session by clicking the End button on
the Tape Client window.

Offline dump format and content

Each command directs the printer to perform an operation or
provides control information used during printing. The dump
format for each of these commands contains a HEADER and
DATA segment.
• If a tape read error occurs while the system is reading the
tape for the dump, and the system skips the block containing
the error and continues reading the tape, the error is
indicated in the dump following the problem block.
• When the system encounters a tape mark while formatting for
the dump, the tape mark is indicated following the block
number.
• The dump of each block, tape mark, error status, end of
volume, or end of data is separated by at least one blank print
line.
