Flow Command Server

Deploy a flow from the HCL Link to the local filesystem using Execution flow server definition.

Use the Flow Command Server to override the flow settings and execute the deployed flow from the command line.

When you run a flow, you can perform the following tasks:
  • Override flow inputs and outputs

  • Set flow variables

  • Enable trace

  • Enable debug mode

  • Define flow audit option

  • Define resource file

  • Set flow execution UUID

Note: The overrides entered when you run a flow do not permanently affect deployed flow artifacts.

Environment variables may need to be set to execute the flow command server. These variables can be set with a setup script which is appropriate for the installation platform. Additional information on special environment variables is given as necessary in other help sections.

On Windows, DTXcommon.bat can be executed before executing a flow command server command line. DTXcommon.bat is in the primary Link installation directory.

For a native Linux installation, the setup script should be sourced before executing a flow command server command line. The setup script is in the root directory for Link binaries which is created after installation. An example of sourcing the setup script and executing the flow command server is given below:
$ cd <Link post-installation directory for native binaries, e.g., tomcat-context/install>

$ . ./setup

$ flowcmdserver -h
