Preinstallation Checklist for the Workflow Engine

Workflow is a tool that automates business processes by putting together a set of tasks in a specific order. For more information, see Workflow: Overview.

Use the preinstallation checklist to prepare the computer where the Workflow Engine will be installed and to gather all of the information you will need during the installation.

Verify System Requirements

Verify that the computer where you will install the Workflow Engine satisfies the minimum requirements specified in System Requirements.

Verify License Requirements

The Workflow Engine does not require a license.

Determine the Installation Location

Based on your environment, install the Workflow Engine on an appropriate computer with the following considerations in mind:

  • The Workflow computer must have direct connectivity to the CommServe computer because it requires access to the database. There should be no firewall configured between the Workflow and CommServe computers.

  • By default, the Workflow Engine is installed as part of the CommServe installation. However, if you plan to offload workflow processes from the CommServe computer, you can install additional Workflow engines on other computers.

  • ForCommvault installations in a clustered environment, you must install the Workflow Engine on the active node first, and then on the passive nodes.

Gather Installation Data

Refer to the items in this section to gather the information that you will need during the installation. Record the information before you begin installing the software, so you can refer to it during the installation.

You can install the Workflow Engine by using the installation package that was created by the Download Manager.


If you plan to install the Workflow Engine on a computer that has other server components installed, only the following information is required:

  • Commvault package to install

  • Destination folder for the Workflow database

Commvault package to Install

Install the Workflow Engine package, which is listed under the Server category.


If the File System Agent is not installed on the computer, the File System Core and File System packages are automatically installed with the package that you selected. The File System Agent will not consume any licenses.

To gather the required information for the File System Agent, refer to the Gather Installation Data section in the Preinstallation Checklist for the Windows File System Agent.

Client computer details

If the File System Agent, or another package, is already installed on the computer, you are not required to gather all the computer details again. The installation program reads the details from the previous installation.

Destination folder for the Database Engine

The database engine is the Microsoft SQL Server software. By default, the software binaries are installed in C:\Program Files\Microsoft SQL Server. You can change the destination folder, but it cannot be on a mapped network drive.

Destination folder for the Workflow database

By default, the database files are installed in C:\Program Files\CommVault\ContentStore. The drive must have at least 1 GB of free space. You can change the destination folder, but the folder cannot reside on the following types of drives:

  • Mapped network drive

  • FAT drive (as it does not allow temporary sparse files to be generated when creating the database snapshot, which is required for data verification)

  • Compressed drive
