If the system abends or is re-started and a dump is taken, you would use the DUMPLOAD command (see HELP DUMPLOAD) to load it from spool onto a minidisk. This will remove the dump file from the spool. You should also be aware that if a dump is taken, that file is closed and CP will pre-allocate space for a new dump file when it restarts (if there is enough space available). >Q:2 how do I print it if I need it?? You don't want to print it. Use the VM Dump Tool (HELP VMDUMPTL) to look at the dump. >Q:3 How do I purge IT if determined that I dont need > it???? You can SET DUMP OFF to remove the pre-allocated dump file, but as has been mentioned in other posts, this is not recommended. Once a dump file has been created, it can either be read onto disk using the DUMPLOAD command mentioned above, or you can use the PURGE commands that others have mentioned to just remove the file from spool if you don't need it. There is some documentation that you might find helpful at http://www.vm.ibm.com/pubs/ I suggest initially looking at: - CP Planning and Administration for allocating and adding spool space - CP Command and Utility Reference for help with QUERY/PURGE/etc. commands - VM Dump Tool for information about reading dump files. You can view these either online or download PDF files from the web page. I also want to reiterate the suggestions that you add spool space. Keeping dump space allocated is highly recommended, and you'll need more spool space for other things once your system starts getting busy. John Franciscovich z/VM Development
