Introduction
CWA Components
Command Line Interface (CLI)
The Command Line Interface program provides access to CWA using
the sacmd.cmd (Windows) or sacmd.sh (Unix/Linux)
program through the MS-DOS command prompt or Unix command utility. You can do things like automate CWA job
control functions by including commands in scripts or by embedding job control functions in the code running your
company processes. The command line program can also be used from the CWA Web Client.

Agents
An agent is a separate installation of CWA
that runs jobs on behalf of the Master. Agents help you to automate the
execution of jobs that you know need to be performed on a regular basis, Offloading jobs to agents frees the Master for
intensive scheduling tasks such as production compiles. Agents exist for various platforms. For the current list of the
types of agents available for CWA, see “Installing Agents” in the
intensive scheduling tasks such as production compiles. Agents exist for various platforms. For the current list of the
types of agents available for CWA, see “Installing Agents” in the
Cisco Workload Automation Installation and
Configuration Guide
. The Windows Agent and the Unix Agent are the two most commonly used agents.
Each agent can connect to a Master by specifying the Master-to-agent communication port and the Master-to-agent file
transfer port numbers.
transfer port numbers.
Adapters
CWA provides adapters for many software products to enable connectivity to and access by CWA. The Master has an
Adapter Host it uses to manage the adapters and is the interface that the adapters use to connect to the Master. Adapters
are provided with the base CWA installation but must be licensed. In some cases, adapters need to be installed or
configured. For a list of the adapters provided for CWA, see “Installing Adapters” in the

Backup Master
The Backup Master is used in a fault tolerance configuration. Fault tolerance requires one Backup Master for each Primary
Master. The Backup Master operates exactly like the Primary Master, but is activated only if the Primary Master
experiences a system, network or —machine failure. The Backup Master must run on the same platform and version of
software used by the Primary Master. The hardware specifications of the backup machine should be equal or greater
than the specifications for the primary machine.

The Backup Master must specify the Backup-to-Master port number for transferring scheduling data from the Primary
Master to keep the Masters synchronized.

Fault Monitor
The Fault Monitor is part of the CWA fault tolerance configuration. The Fault Monitor continually monitors a Primary
Master and Backup Master for error conditions. If a failure indicator appears on the Primary Master, the Fault Monitor
transfers control to the Backup Master. The Fault Monitor must be installed on a separate machine independent from the
primary and backup machines.

Remote Master
A Remote Master is simply an additional CWA Master that is installed in a different environment. The Remote Master
allows a connection to another CWA Master for sharing global CWA variables between CWA environments. Variables
definitions must have “Publish value to remote masters” selected in the CWA environment where they reside prior to
being available through a remote master connection.
