environments that do not already have a TMR server, or one in which a separate
TMR server will be installed for IBM Tivoli Workload Scheduler.
In 16.3.1, “Creating connector instances” on page 492 and 16.3.2, “Creating
TMF administrators for Tivoli Workload Scheduler” on page 495, we discuss in
more detail the steps specific to end-to-end scheduling: creating connector
instances and TMF administrators.
The Tivoli Management Framework is easy to install. If you already have the
Framework installed in your organization, it is not necessary to install the
components specific to Tivoli Workload Scheduler (the JSS and connectors) on a
node in your existing Tivoli Managed Region. You may prefer to install a
stand-alone TMR server solely for the purpose of providing the connection
between the IBM Tivoli Workload Scheduler suite and its interface, the JSC. If
your existing TMR is busy with other operations, such as monitoring or software
distribution, you might want to consider installing a separate stand-alone TMR
server for Tivoli Workload Scheduler.
16.2.3 Install Job Scheduling Services
Follow the instructions in 16.4, “Installing the Job Scheduling Console step by
step” on page 499 to install JSS. JSS is simply a library used by the Framework,
and it is a prerequisite of the connectors.
The hardware and software prerequisites for the Job Scheduling Services are:
Software
IBM Tivoli Management Framework: Version 3.7.1 or later for Microsoft
Windows, AIX, HP-UX, Sun Solaris, and Red Hat and SUSE Linux.
Hardware
CD-ROM drive for installation
Approximately 4 MB of free disk space
For the latest information about the supported versions of these platforms, refer
to IBM Tivoli Workload Scheduler Job Scheduling Console Release Notes,
Feature level 1.4, SC32-1258.
16.3 Installing the connectors
We recommend that when installing the Tivoli Workload Scheduler connector,
you do not select the Create Instance check box. Create the instances after the
connector has been installed.
492 IBM Tivoli Workload Scheduler for z/OS Best Practices
The hardware and software prerequisites for the Tivoli Workload Scheduler for
z/OS connector are:
Software:
IBM Tivoli Management Framework: Version 3.7.1 or later
Tivoli Workload Scheduler for z/OS 8.1, or Tivoli OPC 2.1 or later
Tivoli Job Scheduling Services 1.2
TCP/IP network communications
A Tivoli Workload Scheduler for z/OS user account (required), which you
can create beforehand or have the setup program create for you
Hardware:
CD-ROM drive for installation.
Approximately 3 MB of free disk space for the installation. In addition, the
Tivoli Workload Scheduler for z/OS connector produces log files and
temporary files, which are placed on the local hard drive.
Tivoli Workload Scheduler and Tivoli Workload Scheduler for z/OS connector are
supported on the following platforms: Microsoft Windows, IBM AIX, HP-UX, Sun
Solaris, and Red Hat and SUSE Linux. For the latest information about the
supported versions of these platforms, refer to IBM Tivoli Workload Scheduler
Job Scheduling Console Release Notes, Feature level 1.4, SC32-1258.
16.3.1 Creating connector instances
The connectors tell the Framework how to communicate with the different types
of scheduling engine.
To control the workload of the entire end-to-end scheduling network from the
Tivoli Workload Scheduler for z/OS Controller, it is necessary to create a Tivoli
Workload Scheduler for z/OS connector instance to connect to that Controller.
It may also be a good idea to create a Tivoli Workload Scheduler connector
instance on a fault-tolerant agent or domain manager. Sometimes the status may
get out of sync between an FTA or DM and the Tivoli Workload Scheduler for
z/OS Controller. When this happens, it is helpful to be able to connect directly to
that agent and get the status directly from there. Retrieving job logs (standard
lists) is also much faster through a direct connection to the FTA than through the
Tivoli Workload Scheduler for z/OS Controller.
