What is TWS?What is TWS? TWS is the preferred scheduler option to automate the batchprocessing on Unix systems. It can provide calendar and event

driven workload automation across dierent platforms.

The omposer program is used to manage scheduling

ob!ects in Workload Scheduler"s database. Scheduling ob!ects are

workstations# workstation classes# domains# !obs# !ob streams#

resources# prompts# calendars# and parameters.

Workload Scheduler"s production plan environment is

managed with the onman program.

Scheduling language format and keywords to de$ne

!ob streams for Workload Scheduler.



Getting TWS accessGetting TWS access

We can get the Tivoli access by raising an eS% re&uest. The form name is '

U N - . User /cco%nt 0e1%ests

TWS 7 Terminology Used TWS 7 Terminology Used Wor2station

)lso referred to as %U. Usually an individual computer on which !obs and !obstreams are run. Workstations are de$ned in the Tivoli Workload Schedulerdatabase as a uni&ue ob!ect. ) workstation de$nition is re&uired for everycomputer that executes !obs or !ob streams in the Workload Scheduler network.

Jo#

) script or command# run on the user’s behalf# run and controlled by Tivoli

Workload Scheduler.

Jo# Stream

)lso referred to as schedule. ) mechanism for grouping !obs by function orapplication on a particular day and time. ) !ob stream de$nition includes a launchtime# priorities# dependencies# and !ob names.

Calendar

)n ob!ect de$ned in the Tivoli Workload Scheduler database that contains a list ofscheduling dates. 8ach calendar can be assigned to multiple !ob streams.)ssigning a calendar to a !ob stream causes that !ob stream to run on the daysspeci$ed in the calendar. ) calendar can be used as an inclusionary orexclusionary run cycle.



TWS 7 Terminology Used TWS 7 Terminology Used !ependency

) condition that must be met in order to launch a !ob or !ob stream.

C/0034&0W/0!

The )229:;2W)26 option is de$ned on the schedule if we you want to get theschedule carried forward for the next day’s plan. If the )229:;2W)26 option isnot de$ned# the schedule !ust died down at the <4extday %lan for next day.

0eso%rce

)n ob!ect representing either physical or logical resources on your system. ;ncede$ned in the Tivoli Workload Scheduler database# resources can be used asdependencies for !obs and !ob streams. :or example# you can de$ne a resourcenamed tapes with a unit value of two. Then# de$ne !obs that re&uire two availabletape drives as a dependency. <obs with this

dependency cannot run concurrently because each time a !ob is run the “tapes” resource is in use.

JNextday Plan

The <4ext%lan script runs on the master domain manager to generate theproduction plan and distribute it across the Tivoli Workload Scheduler network.

Symphony

<4ext%lan script creates the new production plan and stores it in a $lenamed Symphony.

)imit

(imit de$nes how many !obs can run at a time. (imit can be de$ned onSchedule1Workload1=aster level.

and %rocessesand %rocesses To generate and start a new production plan Tivoli Workload Scheduler performsthe following steps'

Updates the preproduction plan with the ob!ects de$ned in the database thatwere added

or updated since the last time the plan was created or extended.

2etrieves from the preproduction plan the information about the !ob streamsto run in thespeci$ed time period and saves it in an intermediate production plan.

Includes in the new production plan the uncompleted !ob streams from theprevious

production plan.

reates the new production plan and stores it in a $le named Symphony.

6istributes a copy of the Symphony $le to the workstations involved in thenew product

plan processing.

(ogs all the statistics of the previous production plan into an archive

Updates the !ob stream states in the preproduction plan.
