After system initialization, use the following to change and control
these data sets:
Copy the dump from the SYS1.DUMPxx data set to another data set;
then clear the SYS1.DUMPxx data set, so that it can be sued for another
dump. You can use IPCS to format and view or print the copied dump,
as described in the following topic.
Use the DUMPDS operator command to:
Add more SYS1.DUMPxx data sets on direct access for SVC dumps.
Delete SYS1.DUMPxx data sets for SVC dumps.
Clear a SYS1.DUMPxx data set containing a dump by writing an EOF
mark as the first record. An EOF mark as the first record makes the
data set available for another dump.
A reIPL is not necessary when adding, deleting, or clearing
a data set with the DUMPDS operator command.
Use the REPLY command to system message IEA793A to cancel a dump.
Use a post dump exit routine to copy the dump to another data
set. IEAVTSEL is an SVC dump post dump exit name list that lists the
module names of installation exit routines to be given control when
dump processing ends.
