See also Server Size Guidelines.

Metadata Repository

Important: Composer uses a packaged PostgreSQL database instance to store its metadata. Use the provided instance due to the specific configuration and version combination:

• Logi Composer v24.2 and earlier: PostgreSQL 12

• Composer v24.3 and later: PostgreSQL 16

If you would like to use another PostgreSQL instance, contact Technical Support for further guidance.

Note: New installations of Logi Composer (v24.3 and later) use PostgreSQL 16. If you are upgrading your environment to v24.3 or later, you can retain your existing PostgreSQL version.

Network Requirements

Ports

The following table lists the ports you must consider when installing or upgrading Logi Composer.

Time Synchronization

Logi Composer recommends installing the Network Time Protocol daemon (NTPD) to allow for time synchronization of networked servers to Coordinated Universal Time (UTC), if not already available in your network. See Using the Network Time Protocol to Synchronize Time for guidance.
