- You must issue the DUMPDS command from a console with SYSTEM authority.
- SVC dump supports pre-allocated dump data sets and automatically
allocated dump data sets.
Pre-allocated dump data sets are direct access data sets with names of the form SYS1.DUMPxx, where xx can be any decimal number from 00-99. You can allocate SYS1.DUMPxx data sets with both primary and secondary extents. When you allocate a dump data set, specify enough secondary extents to hold the entire dump. Also, specify RECFM=FB, LRECL=4160 and BLKSIZE=4160.
When automatic allocation is active, the dump is written to SMS-managed storage or to DASD volumes. The system allocates dump data sets of the correct size at the time a dump is requested. No pre-allocation is required for them.
- A DUMPDS CLEAR or DUMPDS DEL command has no effect on any data set that is receiving an SVC dump when you issue the command.
- Symbol substitution is supported on all sub-operands (e.g., ADD, ALLOC, ...) of the DUMPDS command except NAME=. (No substitution is done for the DD NAME=name-pattern command because the name-pattern may contain symbols that need to be passed through unchanged. See Setting the name-pattern for dump data sets for more information about the NAME= sub-operand of the DUMPDS command.)
