Use the DUMPDS ALLOC command to activate or inactivate the automatic
allocation of dump data sets.
DD ALLOC |
DD ALLOC={ACTIVE|INACTIVE}
|
- ALLOC=ACTIVE
- Dump data sets are automatically allocated when a dump is requested.
Any of the resources that have been defined by the DUMPDS ADD command
as available for automatically allocated dump data sets are used.
If no automatic allocation resources are defined, the system issues
message IEA799I and writes the dump to a pre-allocated dump data set
on its list of SYS1.DUMP data sets. If no pre-allocated dump data
sets are on the system's list of SYS1.DUMP data sets, then message
IEA793A is issued requesting operator intervention. The requested
dump is kept in virtual storage until an automatic allocation resource
is defined, a pre-allocated dump data set is made available either
by allocating a new one or clearing an existing one, or the dump is
deleted either by operator request or expiration of the CHNGDUMP MSGTIME
parameter.
- ALLOC=INACTIVE
- This is the initial state of the system after IPL. Dump data
sets are not automatically allocated when a dump is requested. Resources
defined by the DUMPDS ADD command as available for automatic allocation
of dump sets are not used. Any requested dump will be written to a
pre-allocated dump data set specified on the system's list of SYS1.DUMP
data sets. If no pre-allocated dump data sets are specified on the
system's list of SYS1.DUMP data sets, then message IEA793A is issued
requesting operator intervention. The requested dump is kept in virtual
storage until automatic allocation is enabled, a pre-allocated dump
data set is made available either by allocating a new one or clearing
an existing one, or the dump is deleted either by operator request
or expiration of the CHNGDUMP MSGTIME parameter.
Example:
To make the automatic dump data set allocation function inactive,
without changing the automatic allocation resources or naming convention,
enter:
DD ALLOC=INACTIVE
This is the system default.
