[Important Note: I have not actually worked on a cluster, but I see no reason that this shouldn't work.] Another approach to this problem is to have VMS save the system dump in the primary paging file and copy it out early in SYSTARTUP.COM. To do this, don't have a SYSDUMP.DMP file in the normal directory but set the SYSGEN parameter SAVEDUMP to "1". If this is done and VMS crashes, the dump is written to the paging file and that part of it is marked so as not to be used for paging. Then, early in your SYSTARTUP.COM, ANALYZE/DUMP the paging file and give SDA the COPY command. This copies the dump data to a separate dump file and frees the space in the paging file. Another advantage of this method is that the dump file can be located on a different disk. The only disadvantage I know of is that your primary paging file must be large enough to hold the dump and to provide paging for system start-up until you can copy the dump out. -- Ted Marshall ...!ucbvax!mtxinu!blia!ted <or> mtxinu!blia!ted@Berkeley.EDU Britton Lee, Inc., 14600 Winchester Blvd, Los Gatos, Ca 95030 (408)378-7000 The opinions expressed above are those of the poster and not his employer.
