JOB detail sequence errors when two writers serve same database

_PROBLEM DESCRIPTION:
jobs may not appear in the selection list display even though a job
detail record exists.  Jobs may appear slightly out of order in the
selection list display.  A restore job may erroneously create a new
job detail record for the restored job resulting in two entries for
the same job.

_PROBLEM SUMMARY:
USERS AFFECTED: Users running two or more writers against a database.

When a new job is being captured by the writer it assigns the next
absolute job number (ABS#) by incrementing a counter held in an ASPLEVL
record at the start of the .JOBSEQ MASTER file.  This assignment is done
at the same time the next SDS# is assigned and the .JOBSEQ MASTER file
is then closed.   However, a significant time interval can elapse before
the writer actually appends the completed job detail record to the end
of the .JOBDETL MASTER file.  During this interval it is possible for
another writer servicing the same database to assign the next ABS# and
complete its processing and append its job detail record to the end of
.JOBDETL MASTER.  The first writer appends its job detail rec with its
lower ABS# after the second writers job detail record.  The result is
(slightly) misplaced job detail recs which cause the symptoms described.

_PROBLEM CONCLUSION
RECOMMENDATION: Apply PTF ASP0828.

OMCSXWCJ will be modified to insert the job detail record in the correct
place in the job detail master file.
