Defining centralized and non-centralized scripts
A job can use two kinds of scripts, centralized or non-centralized. A centralized script is a script that resides in IBM Z Workload Scheduler and that is downloaded to the fault-tolerant workstation every time the job is submitted.
Centralized scripts
For a job running on a fault-tolerant workstation to use a centralized script, you must define that script in a job definition member of the JOBLIB as you would for a normal job JCL.
Downloading a centralized script
To download a centralized script, DD statement EQQTWSCS must be present in the controller and server started tasks.

      A job can use two kinds of scripts, centralized or non-centralized. A centralized script is a script that resides in IBM Z Workload Scheduler and that is downloaded to the fault-tolerant workstation every time the job is submitted.
      - Centralized scripts
        For a job running on a fault-tolerant workstation to use a centralized script, you must define that script in a job definition member of the JOBLIB as you would for a normal job JCL.

        Rules for creating a centralized script
      - Non-centralized scripts
        For a job running on a fault-tolerant workstation to use a non-centralized script, you must define the script by specifying the JOBSCR or the JOBCMD keywords in the JOBREC statement of a SCRPTLIB member.
      - Configuring the SCRPTLIB
        Jobs that run on fault-tolerant workstations can use solely a non-centralized script or a combination of centralized and non-centralized scripts (if they are to take advantage of the SCRPTLIB statements). These jobs must be associated to members of the SCRPTLIB (identified by the EQQSCLIB DD statement of the controller and the daily planning JCL). You also define some keywords such as the user name, the return code, and the variable substitution in the SCRPTLIB.

    - Tuning global and local options in distributed network
    - Tuning network timeouts
      Network issues that make the connection to specific agents too slow can impact the performance of overall scheduling. IBM Workload Scheduler provides network timeout settings that you can tune to avoid problems with specific agents that affect the entire system.

Downloading a centralized script

To download a centralized script, DD statement EQQTWSCS must be present in the controller and server started tasks.

During the download operation, the TWA_home/TWS/centralized directory is created in the fault-tolerant workstation. The script is downloaded to this directory. If any error occurs during this operation, the controller retries the download every minute for a maximum of ten times. After this number of retries, if the script download still fails, an error with code OSUF is issued.
