EMS Configuration in HAFT Installations

When setting up highly-available or fault-tolerant (HAFT) EMS servers for TIBCO MDM, use database-backed queue storage (against a DB cluster).

This alleviates any issues with SAN boxes and file-based replication. Note that a database-backed EMS storage can negatively impact performance. Consult the EMS documentation to understand the benefits and drawbacks of using EMS. TIBCO recommends that you set the expiry on Change Notification Message queue to a small number, for example one to two minutes.
