Getting Started with Arc

This is the recommended starting point for all new Arc installations. Follow the steps below to get Arc up and running.

Prerequisites

Arc requires TM1 11+ (Planning Analytics 2+). Some features work with TM1 10.2.2, but important APIs are only present in TM1 11+.

Enable the TM1 REST API

The TM1 REST API is required for Arc to function. Enable it by setting HTTPPortNumber in the tm1s.cfg file:

For full instructions, see: Enabling the TM1 REST API

Step 1: Decide Where to Install Arc

Arc can run on a single laptop, on the TM1 server, or on a dedicated server. See for a full breakdown of deployment options and trade-offs.

If your TM1 instances are hosted on IBM PA SaaS, jump directly to:

Step 2: Choose Your Platform and Install

Select the guide that matches your platform:

Step 3: Activate Your License

After starting Arc for the first time, you will need to either start a trial or activate a purchased subscription. See for the full process.

Step 4: Connect to TM1

Arc uses the TM1 REST API to connect to TM1 instances. Once installed, configure your connections in the settings.yml file. See the section for all connection options.
