Installation Requirements

Databridge components must be installed on both the primary and secondary systems.

You must install the current version of Databridge Host software on your primary system before you install Databridge Twin on the secondary system. Go to Install Databridge Host of this guide for Host installation instructions and system requirements.

Databridge Twin runs on all Unisys MCP-hosted mainframes. If you plan to use Databridge Twin and Databridge Host on separate mainframes:

  • We recommend that both mainframes use the same MCP level.

  • Both mainframes must be running the same DMSII level.
