The operator usually takes a stand-alone dump for one of the following
types of problems:
- Disabled wait
- Enabled wait
- Loop
- Partial system hang
When one of these problems occurs, the stand-alone dump program,
residing in the SYS1.PAGEDUMP.Vvolser data set, can be run to produce
a stand-alone dump. There are several procedures that can be used
to run the stand-alone dump program:
When to use which procedure: - Use Procedure A to initialize the stand-alone dump program and
dump storage.
- If you want to run stand-alone dump again, for instance when stand-alone
dump fails, use Procedure B, Procedure C, or procedure D.
- When you want to restart stand-alone dump, try procedure B before
you try Procedure C or D.
- Procedures C and D can result in the loss of some central storage
from the output, whereas Procedure B usually does not.
Although the stand-alone dump program was created under the operating
system, it runs as a stand-alone operation.
