System Requirements

Unless otherwise stated, all Daml runtime components require the following:

  1. For development, one of:
  • x86-compatible systems running a modern Linux or Windows operating system
  • ARM-based Macintosh systems running MacOS 11 or above
  • Deprecated: Intel-based Macintosh systems
  1. For production deployment, an x86-compatible system running a modern Linux operating system
  2. Java 11 or later
  3. An RDBMS system, either:

  • PostgreSQL 11.17-15 (12+ recommended)

    or

  • Oracle Database 19.11 or later

  1. JDBC drivers compatible with your RDBMS

In terms of hardware requirements for development, a simple Daml application can run with a laptop using 2 GB of memory and a couple of CPU cores. However, a much larger environment is recommended for testing or production use.

Please note that the deprecated Intel-based MacIntosh binaries are produced on a best effort basis. At some future point, a lack of Intel Mac machines may preclude building Intel binaries which will result in Intel-based MacIntosh support changing to unsupported and unavailable.

Feature/Component System Requirements

The JavaScript client libraries are tested on Node 14.18.3 with TypeScript compiler 4.5.4. For best results, use these or later versions.
