How to create new APPLICATION in TWS

Step 1. Type M.TWS in ISPF Primary Option Menu and press ENTER

4

How to create new APPLICATION in TWS (contd….)

Then use option 1 to reach TIVOLI WORKLOAD SCHEDULER menu. Option 1 is for Development subsystem where all our development will take place.

“TIVOLI WORKLOAD SCHEDULER” menu. This is the main menu in

which we are going to use most of the options.

6

How to create new APPLICATION in TWS (contd….) Application means a bunch of jobs grouped together. Application can be created in two ways: -

1. Create a new Application

2. Copy from an existing Application

1. Type 1 from TWS menu for creating a new APPLICATION

7


Write the details of the Application to be created like APPLICATION ID, TYPE should be A. Set PRIORITY as 5, give Owner and authority group ID and write OPER in the Command line. All the fields filled below are the mandatory fields (except for the TEXT fields which need to filled.

How to add job in application

Enter work station name operator id and job name. Here the Workstation id is DMMY, operator id is 001 and the job /

operation is DAR0FST.

12

DARG0FST and DARG0LST are dummy jobs. These jobs are used to ensure the beginning and completion of the Application successfully. These jobs are always have DMMY workstation. The operator id of first and last job should be 001 and 255 and rest operation can have operator id with a gap of 10.

You can add jobs by putting R against the row (below the Row cmd) in order to repeat the rows.

Steps to set internal dependency

Dependency between two job in the same application is referred as internal. As shown in the Screen shot internal dependency can be set by using operator id. Job DARG0AB1/2/3 has the internal dependency on first dummy job. DARGLST has dependency on all the above job.

14

If the number of internal dependency is more than 8 use S.1 row command and press enter

Steps to set internal dependency…(Contd…)

15

Enter either operation ID or Operation name and press enter and F3.
