Highly Available or Fault Tolerant (HAFT) Installations

TIBCO recommends using highly-available or fault-tolerant (HAFT) installations in any production or preproduction environment.

To create an HAFT installation, configure several ActiveSpaces nodes across your production and nonproduction environments to support failover. As of TIBCO MDM 8.3.1 release version, you can also create the spaces externally and configure them as needed.

You need not set up the application servers into clustered mode to ensure they are highly available. TIBCO MDM nodes use a load balancer to distribute the load between multiple TIBCO MDM nodes. In most cases, using a software load balancer such as a webserver is sufficient.

Ensure that all TIBCO MDM instances use the same cache configuration file.
