Creating your first TWS Daily Plan

Configuration steps for UNIX Tier 1 and 2 installations

For installations on Tier 1 and Tier 2 UNIX platforms, perform the following configuration tasks.

  1. Create a .profile file for the TWSuser, if one does not already exist (TWShome/.profile). Edit the file and modify the PATH variable to include TWShome and TWShome/bin. For example, if Tivoli Workload Scheduler has been installed in the /opt/maestro directory, in a Bourne/Korn shell environment, the PATH variable should be defined as follows:
    PATH=/opt/maestro:/opt/maestro/bin:$PATH
          export PATH
    In addition to the PATH, you must also set the TWS_TISDIR variable to TWShome. The TWS_TISDIR variable enables Tivoli Workload Scheduler to display messages in the correct language and codeset. For example,
    TWS_TISDIR=/opt/maestro
         export TWS_TISDIR
    In this way, the necessary environment variables and search paths are set to allow you to run commands, such as conman or composer commands, even if you are not located in the TWShome path. Alternatively, you can use the tws_env shell script to set up both the PATH and TWS_TISDIR variables. These variables must be set before you can run commands. The tws_env script has been provided in two versions: See step 1 in Configuring a master domain manager for information about the tws_env script on Windows systems.
  2. To start the Tivoli Workload Scheduler network management process, Netman, automatically as a daemon each time you boot your system, add one of the following to the /etc/rc file, or the proper file for your system: To start Netman only:
    if [-x twshome/StartUp]
    then
    echo "netman started..."
    /bin/su - twsuser -c " twshome/StartUp"
    fi
    Or, to start the entire Tivoli Workload Scheduler process tree:
    if [-x twshome/bin/conman]
    then
    echo "Workload Scheduler started..."
    /bin/su - twsuser -c " twshome/bin/conman start"
    fi

Configuring a master domain manager

After you have installed a master domain manager, if you did not select to automatically add the final job stream during installation and want to do so, follow the steps in this section to add the final job stream to the database and run JnextPlan. This job stream is placed in production every day and runs JnextPlan prior to the start of a new day. The installation creates the FINAL file in the /TWA/TWS directory on your workstation containing the final job stream definition. You can use FINAL or create and customize a new file. See Tivoli® Workload Scheduler: User's Guide and Reference for details about customizing the final job stream.

The following is an example of how to configure a master domain manager after installation:

  1. Log in as <TWS_user>.
  2. Set the environment variables. See Setting the environment variables.
  3. We must now add Schedule Final to the Scheduling Database by using the provided template. Logged in as your TWS admin user, at the “bash” prompt, type the following command after running the tws_env.sh script. It is a good idea to run this script after sourcing your .profile or .bashrc so that you will have the paths to all of the TWS binaries and scripts 

    cd  ~/TWS

    composer "add Sfinal"

    We can now run JnextPlan to create a sample production plan for today.

    Note:

    In general you can add not only default (Sfinal) but any custom  job stream definition by running the following command:

    add FINAL_JOB_STREAM
    where FINAL_JOB_STREAM  is the name of the file containing the definition of the Final job stream. (Default Final job stream supplied with TWS is called Sfinal is just one possibility, see above). You can also customize Sfinal provided with TWS 8.5
     
  4. Run the JnextPlan job:
    JnextPlan
    You can automate this step after installation. See Tivoli Workload Scheduler: User's Guide and Reference.
  5. When JnextPlan completes, check the status of Tivoli Workload Scheduler:
    conman status
    If Tivoli Workload Scheduler started correctly the status returned by the command is Batchman=LIVES.
  6. Raise the workstation CPU limit value to allow jobs to run. The default job limit after installation is 0, so no jobs are permitted to run at a time. Raise the job limit to allow jobs to run, for example to 10 jobs:
    conman "limit ;10"
    If no workstation name is specified for the limit command, the default value is the current login workstation.

    Note:

    If priority of jobs is equal to HI (100) or GO (101), they will disregard the limit and run despite a limit=0, unless fence>=priority.

Additionally, the following configuration procedures might be necessary. For information about these procedures, see Tivoli Workload Scheduler: Administration Guide.

Cleanup Commands: do not do in production:

Get things started after reset (only on a new setup):

JnextPlan

Set limit:

Do a test command job from conman:

 Creating the production day

After you select and configure the length of the production day (as described in 7.1.2, Identifying the length of the production day), you have to create the production day. This section describes the steps to create the production day, and the background details regarding the creation of a production day. The production day is created only on the master domain manager. It must be distributed to all other workstations in the scheduling network before it can be used.

Creating the production day at the concrete level means generating a file called Sinfonia on the master domain manager. It is then automatically copied by Tivoli Workload Scheduler to the Symphony file. After Tivoli Workload Scheduler is installed for the first time, these files do not exist.

 

If you are installing a new instance of Tivoli Workload Scheduler on the master domain manager server, be sure to first add the Sfinal job stream and set the central processing unit (CPU) limit as described in section "Configuring a master domain manager" of Chapter 6, "Configuring after installation" of IBM Tivoli Workload Scheduler Planning and Installation Guide v8.3, SC32-1273.

If the Symphony file does not already exist in the TWShome directory of the master domain manager server, you can run JnextPlan manually.
