PDL principles and procedures Dumps The dump feature is a troubleshooting tool for print jobs. It allows you to generate a hardcopy of the command and data transmission between the host computer or the magnetic tape and the printing system while a job is being transmitted and printed. Online dump The online dump provides a printout of all the command and data transmission taking place between the host computer and the printing system. Starting and ending online dump sessions To print a dump of an online job you wish to troubleshoot, follow these steps: 1. Specify the DFLT JDE and the OLDUMP JDL on the Online Job Manager window at the print server. (The OLDUMP JDL, which was loaded on your system at installation, contains the VOLUME HOST=OLDUMP 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 Online Job Manager window. Online dump format and content Each host command directs the printer to perform an operation or provides control information used during printing. The control information could be printed with carriage control only or printer control, such as load FCB. All print commands and some control commands transmit data to and from the printing system. The dump format for each of these commands contains a HEADER and DATA segment. The HEADER segment consists of the fields shown in the following table. 1-74 Using LCDS Print Description Language
