Overview

A message store is a store for JMS messages in a JDBC database. It gives better scalability and query capabilities than holding messages in XML files.

Note This is an experimental feature subject to change, especially the schema.

Configuration

The default JDBC URL is jdbc:derby:MessageStores;create=true. This will create the MessageStores directory using Derby in your .hermes directory. You can override this to be any JDBC URL with the property hermes.messageStore.url

When a database is used for the first time, Hermes will automatically create the tables it needs to store the messages.

Features

View the message store and replay tutoirals. Currently you can:

• Drop messages into a store from a queue or topic.
• Drag messages from a store onto a queue or topic.
• Record messages into a store from a queue or topic. For a queue this means taking a snapshot of the queue with a QueueBrowser, for a topic Hermes just keeps reading messages from the topic and storing them until you stop it.
• Browse all the messages in the store or browse by originating topic or queue
• Delete individual messages, all messages from a queue/topic or an entire message store
• Replay messages from a message store.
