PDL principles and procedures Offline dump 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 print server. (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. 1-76 Using LCDS Print Description Language
