Introduction

For DCM 2.0, Blueriq uses asynchronous messaging. Message handling could sometimes fail for different reasons. The DCM Maintenance Application gives the functional administrator the insight and control needed to maintain a DCM system of applications and ways to restore from errors.

The DCM maintenance application:

• Retries a message for which the handling failed automatically
• Gives insight and control over messages that failed more than a configured number of retries
• Gives insight and control over crashed (stale) locks
• Gives insight into overdue scheduler tasks
• Gives insight into the state of a case

The DCM Maintenance Application consists of a Spring Boot service that performs the work and comes with an Angular based user interface.
