Jim
Damon, Senior Systems Engineer
Computer Corporation of America |
|
It's
hard to imagine one of the world's fastest databases
getting even faster, but that's exactly what we've done
in the latest release of Model 204. This session explores
the new performance-oriented features of Model 204 V5R1,
including:
v Support
for 64-bit z/OS, which helps you accomplish more work
in less time by keeping server pages in memory and
eliminating excessive page swapping.
v The
V5R1 performance pack. Understand how new internal
features can give you performance benefits with no
effort on your part.

| Streamlining
Restart Recovery |
Rick
Puszewski, Principal Software Engineer
Computer
Corporation of America |
|
Recent
versions of Model 204 have seen dramatic improvements
in Model 204's reliability. But just in case your system
does go down, V5R1 will help you get it back up more
easily than ever before. This session explains how we
have eliminated secondary recovery and streamlined the
new, single-step recovery so that you will experience
as little downtime as possible, resulting in a more
efficient and less complex RESTART recovery process.
It will also discuss the performance improvements associated
with this process. Finally, Rick will briefly touch
on two additional performance features: Regen, with
its faster new ONEPASS option, and XDM for CRAM users.

| External Call
Facility (ECF): Invoking External Procedures from User
Language |
Leonard
Gradus, Product Architect
Computer Corporation of America |
|
Today's
IT infrastructure is a heterogeneous mix of expert tools
that are just right for certain jobs. The challenge
is figuring out the best way to integrate them when
sharing information or procedures is required. The External
Call Facility, or ECF, makes it easier than ever to
invoke external procedures without the restrictions
of yesterday. So you can fully leverage existing non-M204
code from within your User Language applications, thereby
eliminating functional redundancy and expediting application
development time. CCA believes that ECF will become
the cornerstone of many advanced, sophisticated, multi-platform
environments, and this session will explain how you
can fully exploit it.

NonStop/204: Perpetual Processing and Thread Synchronization
|
Jim
Stepasiuk, Senior Database Consultant
Computer Corporation of America |
| To
support the Internet-driven need for 24x7 availability,
Model 204 V5R1 includes a new non-stop processing capability
known as NonStop/204. With NonStop/204, you can schedule
in-flight backups without bringing down the region. Model
204 will then re-initialize your CHECKPOINT dataset, close
down the JOURNAL and resume processing with new files.
This session discusses this new facility in detail and
explains how to deploy it in your environment. |

| MQ/204: Integrating
Model 204 with the Enterprise |
Marie
Kelly, Director of Marketing
Bill Laub, Product Architect
Computer Corporation of America |
|
Like
ECF, MQ/204 is another solution to the problems caused
by heterogeneous IT infrastructures that beg for seamless
integration between "islands of automation".
IBM answers the cry with Websphere/MQ (a.k.a. MQSeries),
its message queuing middleware product that allows you
to easily exchange information across more than 25 different
operating systems. MQ/204
from Computer Corporation of America provides full support
for Websphere/MQ from within Model 204, allowing Model
204 applications to communicate with nearly any other
business application on the network. This session provides
an overview of MQSeries and MQ/204, and discusses new
features available in MQ/204.

Scinta, Senior Technical Consultant
Kim Collins, Model 204 Consultant
Computer Corporation of America |
|
Living in the "Information
Age" is only significant if we are able to transform
raw data into business information, and derive non-intuitive
relationships between data that drive new business initiatives.
That's exactly what CCA Analytics is designed to help
you do, and with the latest release - V2R1 - it just
got even better. This session provides an overview of
CCA Analytics, followed by a discussion of key new features,
including improved administration dialogues and security
features. But above all, Analytics now has the ability
to share object stores so you can collaborate with your

| Software
Measurement: How to Prove that Model 204 is Better than
the Alternatives |
Ron
Salvador
Moon Brook Hill |
Most
organizations use lines of code (LOC) to measure productivity.
However, LOC is neither goods nor services in the economic
sense. The standard economic definition of productivity
is "Goods or services produced per unit of labor
or expense." Users do not purchase code directly.
LOC is not the primary product of software projects, and
cannot be used for most estimates for application software.
Function points are a measure of the size of computer
applications and the projects that build them. The size
is measured from a functional, or user, point of view.
It is independent of the computer language, development
methodology, technology, or capability of the project
team. Function points, unlike lines of code, can be used
for economic studies, such as effort, staffing, defect
rates, application size, project estimation, and other
cost-related studies. The function point metric is by
far the most widely utilized software metric in the United
States.
Because function points can measure applications independent
of technology, it can objectively show the benefits of
developing applications with Model 204. This mildly technical
seminar will explain how software measurement can be used
to show that application development in other technologies
might have no cost savings, if not do worse, compared
to Model 204. It will also show how much a replacement
application might cost; if the cost of replacing an application
in another technology be really known, more sites might
choose to enhance their current assets rather than replacement
at greater cost.
A similar paper was delivered last fall at the GTC East,
the largest government-related conference in the United
States. |

| Recent
Developments at Centrelink |
Rob
Schoenberg
Centrelink |
The
External Call Facility (ECF) enables Model 204 onlines
to easily access non-user language procedures. Why and
how Centrelink uses it are discussed: with the roles of
the DBA in implementing it; and of the applications teams
in using it, detailed. The commands available to manipulate
the Facility are discussed, as well as the development
/ testing tool Centrelink has built over these.
Centrelink Model 204 data holdings are growing at a rate
of over 40% per annum. The reasons for this and the responses
by the Data Base Design team (including how to optimize
the performance improvements in Version 5.1) to limit
the performance 'hit' of this growth are reviewed. |

| An
Automated Change Management System For Model 204 |
Paul
McPhee
Calgary Police Service |
The
Calgary Police Service has developed an automated change
management system that greatly reduces the risk of human
error when changes are implemented to production. This
gives our developers a high level of confidence that changes
to the production environment will be complete and trouble-free.
Our system, called the Change Control Management System,
includes the following features:
1. A change profile that includes information such as
Change Number, Requested Date, Required Date, Work Request
Number (cross-reference to original user request), Urgency,
Platforms Affected, Applications Affected and Target Environments
(user test and/or production).
2. A text editor to create a free-form description of
the change and detailed instructions.
3. Screens to select M204 procedures (any number of procedure
files), tables and messages to be implemented.
4. An export function that copies all objects being implemented
to holding area until they are implemented. This gives
the developer the assurance that all objects being implemented
are synchronized as of a single point in time, and allows
developers to start work on the next version before the
current version has been fully implemented to production.
5. Hard copy report of the change, with areas for authorization
signatures (optional).
6. Operators get a list of changes ready for implementation
in the target environment. All objects in the change set
are implemented with a single key stroke by the operator
(a major improvement over our previous change systems).
7. The previous version of each implemented object is
copied to a backup file and retained for 1 week.
8. Audit trails showing date, time and a list of all objects
implemented or backed-out.
9. Online inquiry of previous and pending changes.
The presentation walks through the change process, highlighting
technical details along the way. |

| Using
the Ordered Index - Is This Trip Necessary? |
Robert
Waggoner
Nodus, Inc. |
| Model
204's Ordered Index and its implementation of bit
pattern technology plays a big role in the incredible
performance of the DBMS. However, programmers sometimes
use “overkill” when using the ordered index,
incurring unnecessary Disk I/O and Critical File Resource
locks. The problem of finding and fixing these code “hot
spots” among a shop's millions lines of code
is facilitated by using Sirius Software's SIRTUNE
product. This presentation illustrates best practices
for using the Ordered Index for retrieval and ordering
of data, and practices to avoid. |
