TWS/Graph – Some basic information
Before we’re starting with the training, we like to
give some basic information about TWS/Graph:
• TWS/Graph is the successor of OPC/Graph
• TWS/Graph can read and display data from “TWS for z/OS” and “TWS
for Distributed”
• In connection with “TWS for z/OS” the product can be used offline or
online

‘SYS.TWSGRAPH.V4R0.MODELS

What is a Model?
It is a combination
of Input- and Output

Alternatively, the search can be
performed on the complete input file or
ONLINE by using the integrated
communication feature. All predecessors
and successors can be selected, and not
only those which are already displayed in

ONLINE may result in bad performance. For
subsequent analysis of predecessors and

What is the difference between application
and operation level?
•
On application level only external dependencies are taken
into account. Performance is better, but resulting netplans
are usually bigger.
•
On operation level internal and external dependencies are
analyzed. Performance is slower, but the netplans are
easier to read.

The reason for the loop is one (or more) wrong

How does it work:
• TWS/Graph reads the sysprint file to get the names of
applications that are in the loop
• This names are used as a selection criteria to build an

• The PC-Client provide a function to detect all operations
that are on the loop
• Finally you have to decide which dependencies are wrong

This chapter explains how to analyse the
critical path:
• Based on your knowledge about critical jobs.
- In this case, the critical path is formed by all predecessors of your
critical end job(s)
• Based on TWS values.
- The path with the longest duration
- The path with the latest end times
- The path that is flagged by TWS as critical

Critical Path based on TWS values
In opposite to the method described before,
there are other ideas about the critical path:
• The critical path is the job stream with the "longest"
duration.
• The critical path is the job stream that has the "latest" start
times
• The critical path is flagged by using the TWS value "on
critical path"
HORIZONT
204
TWS/Graph
Critical Path based on TWS values
If you want to search for the critical path
based on "longest duration" or "latest" start,
you must take into account:
• TWS has planned start- and end times.
These values are useful before production starts
 Useful to find out what will happen!
• TWS has actual start- and end times.
These values are useful after production has ended
 Useful to find out what has happened last night!
HORIZONT
205
TWS/Graph
Critical Path based on TWS values
Load a current plan

the critical path
function.
A known problem is that TWS/Graph requires a netplan to search
for the critical path. If you cannot load the whole production into
one netplan, you should use the functions as described in
previous chapter to get smaller netplans.

wrong
• Select Actual if you want to analyse what happened last night.
 Use TWS/Graph's batch unload to extend the data right before the extend
of the current plan, otherwise the data is lost!
• Select TWS Flag to see which jobs are flagged by TWS as critical

 How does that work?
TWS/Graph searches for the latest job in the netplan (based on
planned or actual end time). All predecessors of that job are
analysed, the latest job is marked. From that job all prdecessors are
analyzed…(and so on)

Summary about the Critical Path
• There is no single method to analyse the critical
path, but there are several ways.
• You must decide yourself what fits better to your
needs.
• TWS/Graph can analyses the path based on TWS
data. If the estimated durations are wrong, then the
calculation performed by TWS/Graph will be wrong

How to use TWS/Graph to avoid delays
TWS/Graph can be used to find out if production will
be in time, or if there are delays. There are some
basic techniques to do that:
• Milestones
• TWS/Graph and OPC Deadline times
HORIZONT
271
TWS/Graph
Milestones
Probably the best way to monitor the
Critical Path is to insert milestones and to
monitor them with TWS/Graph
HORIZONT
272
TWS/Graph
Milestones
Now the same application with milestones (yellow symbols)
PS: We used the TWS/Graph function ”Search for redundant links” to
clean up the application
HORIZONT
273
TWS/Graph
Milestones
The status monitor of
TWS/graph needs one
object for every milestone
HORIZONT
274
TWS/Graph
Milestones
The monitor signalises if a milestone is late.
In this case the daily production was delayed
right after the start at 10:00
HORIZONT
275
TWS/Graph
Pros and Cons
We think Milestones is the best method to monitor
thousands of jobs:
+ Simply to use
+ Excellent performance
(TWS/Graph must monitor only the milestones, and not the
whole stuff)
- Milestones must be maintained
HORIZONT
276
TWS/Graph
Using TWS-"Deadlines"
TWS/Graph offers alternatives to monitor the critical
path:
• TWS/Graph allows to check automatically all predecessors of a critical
job (e.g. the online start). If one preceding job exceeds its deadline, the
status LATE is shown.
• To do this you must specify '00:00' in the 'late time' field and 'Operation
Deadline' in the 'late time origin' field. As long as you have coded
deadline times, the monitor produces late alerts for these if they are in
your monitored critical path. And if there is a known delay to the start of
batch by, say 2 hours, you only need to change the 'late time' field to
'02:00' for one monitored job (last one in the critical path)
HORIZONT
277
TWS/Graph
What are TWS Deadlines?
The deadlines we are using in our function
are the operation deadlines. They have to be
specified in the application descriptions of
TWS.
HORIZONT
278
TWS/Graph
Using TWS-"Deadlines"
1. Find out the last job in
your critical path, e.g. the
online system. In our
example the last job is
T82030050A-99
HORIZONT
279
TWS/Graph
Using TWS-"Deadlines"
2. Define an object in the
status monitor that points
to the critical job
The late time must be
specified as an offset to the
deadline. If you specify
00:10, and the deadline in
TWS is 12:30, the job will
be late if it is not complete
until 12:40.
The critical job
Specify 99 for all
predecessors
HORIZONT
280
TWS/Graph
Using TWS-"Deadlines"
3. After having started the monitor,
TWS/Graph checks automatically
all predecessors of the critical job.
HORIZONT
281
TWS/Graph
Using TWS-"Deadlines"
4. The status monitor
shows LATE if any
preceding job missed the
deadline
(remember: the deadline
has to be specified in the
application description of
TWS)
HORIZONT
282
TWS/Graph
Using TWS-"Deadlines"
5. If you like to see which
job missed the deadline,
you must select “netplan”…
HORIZONT
283
TWS/Graph
Using TWS-"Deadlines"
6. TWS/Graph shows the
netplan with all predecessors
of the critical job, all jobs that
missed the deadline are
marked (here pink).
HORIZONT
284
TWS/Graph
Pros and Cons
In opposite to the “old” method of using milestones
this new function has some disadvantages:
- Operation deadlines must be maintained in TWS.
- Poor performance (TWS/Graph must locate and
analyse all predecessors)
+ In case of delays the monitor can be adjusted
easily, only the ‘late’ time must be modified in the
status monitor
