what is tws webadmin for z os
What is TWS/WebAdmin for z/OS?

TWS/WebAdmin is a Web interface for "TWS for z/OS". The AD (application description) and the CP (current plan) are kept in a separate, synchronized database. Main functions are:

  • Create, delete or modify („design") applications and operations (jobs)
    • Prepare it in TWS/WebAdmin’s own database
    • If it\'s time to go in production, move it to TWS
    • Print your application descriptions by clearly arranged reports
  • Simulate modifications and verify the critical path at any day in the future
  • Search, query, analyse your TWS operations, dependencies etc.
  • View AD and CP in high quality graphical
    • Job and application flowcharts
    • Bar charts
  • Monitor your jobs in the CP and/or in past (historical) CP versions
  • Use the Status Monitor to
    • Define business process views and generate public HTML pages
    • Generate automatic alerts in case of critical jobs are late or in error
  • Insert “ad hoc jobs” to the CP or LTP (long term plan)

create or modify applications
Create or Modify Applications

Click on AD

“List, Modify, Delete

Specify search criteria like application id, owner etc.

modify application
Modify Application

Your applications. Based on the internal security system (user/groups), you may see only yours.

Column "State" shows the status in TWS/WebAdmin’s DB.

"Actual" means that this version is currently in TWS,

"History" are older versions,

"Modified" means that the application was changed, up to now only in TWS/WebAdmin’s DB

Select an application to e.g. modify

modify application1
Modify Application

To create a copy, change the „Application id" and press „OK"

Based on the internal security system (user/groups), all fields can be initialized with default values or made “read only” or hidden

"Predefined Run Cycles" simplifies the Run Cycle definition and “Show Run Days" shows an preview of the scheduling (like "Gendays")

Modify Operations or Run Cylces

modify operation
Modify Operation

Modify repeat or insert operations, or select “Operation Detail“, “Dependencies“ or “Special Resources" etc.

Use Netplan to view it graphically

modify dependencies
Modify Dependencies

Predecessors and Successors can be defined. In case of external successors, the predecessor applications will be updated automatically

modify dependencies1
Modify Dependencies

"?" brings up selection list

modify dependencies2
Modify Dependencies

Easy to read job netplans (flowcharts) to verify the dependencies graphically.

Yellow colored boxes show changed applications, blue boxes show current (“actual") versions

modify run cycle
Modify Run Cycle

You can work like in TWS using Periods, Rules, Free Day Rules etc.

modify run cycle1
Modify Run Cycle

You may also use

“pre defined run cycles“

which are prepared by your administrator

You don’t need to know anything about input arrivals, periods, free day rules etc.

verify run cycle
Verify Run Cycle

“Show Run Days" gives you a clear preview

modify application2
Modify Application

Click on “OK" to save the changes to TWS/WebAdmin’s DB

tws update
TWS update

If you are done and it’s time to bring it in production, you can start the “TWS update".

You need RACF update authority in TWS z/OS.

The update may also be done by an administrator.

modify application3
Modify Application

The new versions get state “Actual", the old versions “History"

Check one or more applications and click Report to get a printable documentation

application report
Application Report

Select the parts which the report should contain (Netplan will come soon)

Simulation

You can modify e. g. dependencies or durations just for simulation

There are useful mass update rules like e.g. add 10 percent to estimated duration to all CPU operations

simulation2
Simulation

If you press “Simulate”, the critical path will be calculated and the critical operations are marked

You can sort by (calculated/expected) start time and see when your jobs will run

simulation3
Simulation

In the netplan view you can see the red marked jobs on the critical path

For more details about the simulation feature and forecasting, please see TWSWebAdmin zOS - Simulation.ppt

query applications operations in ad
Query Applications/Operations in AD

Query AD offers powerful queries to search e.g. for “Critical Path Target" jobs etc.

Cross one or more TWS systems!

“Query AD Database” offers powerful queries to search e.g. for “Critical Path Target" jobs etc.

Cross one or more TWS systems!

The result shows the operations and the special resource usage etc.

There is also planned start/end and actual start/end which an be used to sort in runtime sequence

cp history
CP History

If a new CP has been created, each “old” CP is stored to the history database

Select desired old CPs and

"Set and go to …"

Creation date of the CP

cp history1
CP History

Now you can search e.g. when a job was scheduled and when it did run.

Select the needed CP versions and e.g. one critical job.

cp history2
CP History

Here you can see the planned start, actual start/end and it’s duration of the last runs.

cp history3

Double click for details

"Expanded" view shows operations

Optional time line (trailed by mouse)

status monitor
Status Monitor

The administrator defines one or more “Status Monitor Trees” and the Jobs to be monitored (see next slides)

The Monitor optional generates HTML output to e.g. a public shared path

The Monitor optional generate alert emails, e.g. in case of error or late jobs

status monitor1
Status Monitor

Define Groups in hierarchical order, Applications and Operations to be monitored and give them self explaining names like payroll, accounting etc.

Enter generic or detailed (milestones) search criteria and optional parameters, e.g. when it should be completed

status monitor2
Status Monitor

Once the monitor is started, it reads TWS/WebAdmin’s synchronized CP database and calculates the status of each object and shows it in status colors (waiting=grey, ready=yellow, started=green, error=red, completed=blue)

status monitor3
Status Monitor

Depending on the refresh rate (e.g. one minute), it shows the new status

The monitor optional send an email if something ended in error or is late

status monitor4
Status Monitor

Late time can be based on TWS times (input arrival, planned start, deadline etc.) and in addition calculated on the non completed predecessors of a end job

The monitor shows the remaining duration of the critical predecessor path (here 51 min 04 sec) and the remaining buffer from the current time to the required end time (here +9 min, therefore it’s still ok)

status monitor5
Status Monitor

The generated HTML can be placed on a shared folder. The top down links follow the monitor tree hierarchy.

Specify useful descriptions, so that everybody can easily find his own jobs

Next slide

status monitor6
