You can change the dump mode or options for a dump type. Before
making a change, however, issue DISPLAY DUMP,OPTIONS to see the current
mode and options.
Changing the mode of a dump type can also affect its system dump
options list as follows:
- If you change the mode for a dump type from OVER to ADD, the system
adds the dump type’s parmlib options to the dump type’s system
dump options list. The dump type’s system dump options list then
contains both the dump type’s parmlib options and any options set by previous CHNGDUMP commands.
- If you change the mode for a dump type from ADD to OVER, the system
removes the dump type’s parmlib options from the dump type’s
system dump options list. The dump type’s system dump options
list then contains only the options set by previous CHNGDUMP commands.
- If you change the mode for a dump type to NODUMP, the system empties
the dump type’s system dump options list.
If you make an error entering a CHNGDUMP command, the system rejects
the entire command and issues an error message.
