Read-Only Mode

The Content Engine can be configured to use a read-only connection to the database. Read-only mode can provide a useful means of:

  • Ensuring that presentation hosts do not make modifications to the database.

  • Scaling up the presentation layer by connecting presentation hosts to a read-only slave database.

When a Content Engine is running in read-only mode:

  • All write operations to the database will fail.

  • None of the Content Engine's mutex services (services designed to run on only one host) will start.

  • Content Engine plug-ins that depend on write access to the database, such as the Viz Community Expansion, Forum and Poll, will not work.
