the time, was new to both the vendor (IBM) and to Norwest. The
Norwest users found DB2 to have a slow response time; consequently,
as users queried the database files for access to data, the queries
became backed up--each query waiting for the query ahead of it to
be completed. Although the resolution of this problem was
important, it involved no more than basic troubleshooting by IBM
and NTS personnel.
Another problem, which was similar to the one resolved by the
shadow file system, involved the great number of batch jobs
processed each evening. Because of the large number of users who
wanted reports processed following the evening updating, the
mainframe often became locked out (known as getting IO bound) so
that jobs requiring access to the same data at the same time could
not be completed. As a result, NTS both developed a system that
provided multiple data files for the jobs to run against and
created a mainframe scheduling system that allowed an organized
processing of the batch jobs.
There were several other, albeit smaller, projects that were
addressed by NTS personnel during the years in issue, ranging from
report writer customization to new releases to interface tasks.
