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

TWS/Graph – Advanced Techniques Predecessors and Successors

Predecessors and successors
There are two options with TWS/Graph to search for all predecessors and successors of an application or operation: Search within an existing netplan Search directly in the database goto goto HORIZONT 98 TWS/Graph 8 3 3 8 3 4 4 11 12 12

Every option has its pro and cons: Search within existing netplans is fast, but only applications or operations which are already displayed are taken into account Search from the database can be slow, especially when it is performed ONLINE HORIZONT 99 TWS/Graph 8 3 3 8 3 4 4 11 12 12

Search within netplans
1. Click with the right mouse on the start job HORIZONT 100 TWS/Graph 8 3 8 3 3 11 4 4 12 12

2. Select “Mark successors” HORIZONT 101 TWS/Graph 8 3 8 3 3 11 4 4 12 12

4. Select SUBNET 3. The successors are marked HORIZONT 102 TWS/Graph 8 3 3 8 3 4 4 11 12 12

5. The resulting netplan with all successors HORIZONT 103 TWS/Graph 8 3 8 3 3 11 4 4 12 12

I need all successors from more than one startpoint. How can I do this? Mark all startpoints HORIZONT 104 TWS/Graph 8 3 3 8 3 4 4 11 12 12

Click with the right mouse somewhere on the whitespace Select “Mark successors”… HORIZONT 105 TWS/Graph 8 3 3 8 3 4 4 11 12 12

The Result HORIZONT 106 TWS/Graph 8 3 8 3 3 11 4 4 12 12

Summary: The function "all Predecessors and Successors" has some disadvantages 1. All levels are searched. 2. Only operations which are displayed in the actual netplan are taken into account. HORIZONT 107 TWS/Graph 8 3 8 3 3 11 4 4 12 12

Load Predecessors and Successors
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 the actual netplan. ONLINE may result in bad performance. For subsequent analysis of predecessors and successors it may be more efficient to download the complete AD or CP manually from OPC (click here for more information how to download files manually) HORIZONT 108 TWS/Graph 8 3 3 8 3 4 4 11 12 12

Open HORIZONT 109 TWS/Graph 8 3 8 3 3 11 4 4 12 12

Select “Load predecessors and successors”… Check this box if you like to search ONLINE HORIZONT 110 TWS/Graph 8 3 3 8 3 4 4 11 12 12

If you specify any operation criteria: The search is performed on operation level... specify the start application... HORIZONT 111 TWS/Graph 8 3 3 8 3 4 4 11 12 12

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. HORIZONT 112 TWS/Graph 8 3 3 8 3 4 4 11 12 12

TWS/Graph loop analysis
The reason for the loop is one (or more) wrong predecessor definition in the application description. In this case TWS is not able to create a valid plan TWS/Graph helps you to find out the operation(s) that are responsible for the problem.

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

If you cannot use the TCPIP communication between TWS/Graph PC-Client and Host: From TWS/Graph‘s ISPF dialog, call option 4 and generate an output file. Transfer the file to your PC.

Select application decription Turn off external pred/succ

Specify the filename of the SYSPRINT. It is allocated dynamically and read by the TWS/Graph host task.

The result is an operation netplan, including all operations of all applications that are in the loop

Select Search Loops

All operations on the loop are marked

Click on Subnet

You have to find a correct point to “cut” the chain

Critical Path 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 knowledge
Critical end job Mark Predecessors

To find the critical path, you must use the functions to locate "Predecessors and Successors". Please review these chapter again, if you are unsure about these functions.

Click on "subnet" to extract the critical path

The netplan with the critical path And how long is the duration?

Select "Search-Critical Path", but all you need to know about that is described on the next slides.

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"

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!

Load a current plan netplan, and activate 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.

Select "Planned" or "Actual" Select "Ent time" or "Duration"

Select Planned if you want to analyse what will probably happen in the next planning period Please note that the values for "estimated durations" (Application description) must be more more or less correct. Otherwise the result will be 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 We are sorry, but we never found out which criteria TWS uses to mark jobs as "critical"

Critical Path based on TWS Flag
TWS ISPF dialog option 6.3, scroll right: “Critical Path Flag”

Select Duration if you want to find out which path has the longest duration in total. Select End time if you want to find out which path will delay next production cycle (if you selected Planned), or which path delayed previous production cycle (if you selected Actual) 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)

Results of the Critical Path based on TWS values
The subsequent examples will show you that the critical path can be different, depending on the method you have selected.

Results: Critical Path by duration
The path with the longest duration (in total) forms the critical path (red boxes)

Results: Critical Path by End Time
Search for the last job, analyse the predecessors of the last job, from the predecessors take the last job...

Results: Critical Path by TWS
TWS/Graph marks the jobs that are marked by TWS as critical...

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

Statusmonitor This chapter will show you how to use TWS/Graph to monitor your production. Error!

Statusmonitor TWS/Graph overs two different ways to monitor production
Simple Monitor for small productions or extracts (<500 jobs) Complex Monitor for complete Production

A simple monitor Open a netplan from the current plan

A simple monitor Specify selection criteria… (Use * only for small productions)

A simple monitor Not more than 500 applications !

A simple monitor Specify refresh rate Select update Statuscolors…

A simple monitor Status colors

A simple monitor Show colors

A simple monitor Red shows errors

Monitoring Production?
Is it possible to monitor a complete production? Technically yes, but…

Monitoring Production?
The problem: A complete production is too big for graphical monitoring!

Monitoring Production with TWS/Graph
The solution: Monitor the critical path, and not the complete production!

TWS/Graph Status Monitor
TWS/Graph has an integrated Status Monitor. It can be used to monitor your production: Monitor the critical path Monitor Milesstones Monitor if production is late Create HTML files with actual status information Send Alerts ( or WTO to SYSLOG)

Identify Critical Jobs
As a first step you must know what you like to monitor, and how to group these jobs logically, e.g. by functionality, by owner, by department etc.

Define Structure After you've made a decision what you like to monitor, you must define a structure

Define Structure Now this empty structure must be filled up with objects: Groups Applications Operations

Define Structure Use the right mouse to insert objects into the empty structure

Define Structure Top Level, e.g. the OPC subsystem

Define Structure Next Level, e.g. Operations

Define Structure Do you want to get a list of all jobs that are in error?

Define Structure Or do you want a list with all jobs that are started?

Define Structure Or do you like to monitor all jobs that are defined in OPC to be monitored? (available with TWSz 8.1)

Starting the Monitor Start

Starting the Monitor Refresh all 5 minutes
Write status information to HTML

Status Monitor is up and running
No job is in error Jobs are active Some critical jobs are done, some others are still waiting After the refresh the colors are changed, every colour has a special meaning

Job(s) in error Job(s) are active

All netplans can be loaded directly from the monitor, here are the active Job(s)

Complex Monitoring e.g. for special jobs
...and jobs for several departments The structure should be defined in a way that allows to monitor all interesting elements from one screen: The Focal Point

Define more Jobs/Applications

How to monitor late jobs

The jobs is „late“, if it is not complete until 18:00 Selection criteria: One or more jobs (generic selection)

These job(s) are „late“, if they are not complete until 18:00. 06:00 (=IA) + 12:00 Std. = 18:00 Selection criteria

“Late” Monitor is up and running

“Late” Monitor is up and running
Job (and superior levels) are „late“ The superior Level is still red, because ERROR has higher priority than LATE

Alerts After every refresh any program can be called from TWS/Graph.

Alerts Create Message Send Email
TWS/Graph has an integrated REXX interface. Parameters like the jobname or the status can be passed as a parameter to a program

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

Milestones Probably the best way to monitor the Critical Path is to insert milestones and to monitor them with 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

Milestones The status monitor of TWS/graph needs one object for every milestone

Milestones The monitor signalises if a milestone is late. In this case the daily production was delayed right after the start at 10:00

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

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)

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.

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 T A-99

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

Using TWS-"Deadlines" 3. After having started the monitor, TWS/Graph checks automatically all predecessors of the critical job.

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)

Using TWS-"Deadlines" 5. If you like to see which job missed the deadline, you must select “netplan”…

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).

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
