Rhapsody Datastore

The Rhapsody datastore is a file-based system used to store the engine configuration and state information as well as the message archive.

The default location for the datastore files is <RhapsodyInstallDirectory>\rhapsody\data.

Sub-directory	Description
`\backup`	Contains the backups schedule.
`\charactermap`	Stores the global mapping file, `characterMapping.xml`. Refer to Global Mapping File for details.
`\cleanup`	Holds configuration details that control when cleanup is performed.
`\cleanuptrace`	Contains the cleanup trace log files used by the Management Console.
`\commpoints`	Contains indexes for certain communication points.
`\config`	Contains the Rhapsody configuration.
`\filters`	Used by the Duplicate Message Detection filter to store the data structure for tracking duplicate messages.
`\idgeneration`	Stores persistent information about the current state of each ID generator.
`\index`	Contains indexes created to access properties on messages.
`\lib`	Contains external libraries that are common between many communication points. For example, you can add third-party JDBC drivers here instead of attaching them to each individual communication point. However, if you attach a library to a communication point it will override any library that is in this directory.
`\logs`	Contains the following log folders used by the Management Console: `\logs\audit` `\logs\component` These files are not text logs, and should not be attached to support tickets. The text logs can be found in the `log` directory under the main Rhapsody binaries directory.
`\lookuptable`	Contains the following databases: `lookuptable` – contains lookup table data. `failure` – contains lookup failures that were recorded during the lookup process.
`\messageevents`	Contains data about events that occur to messages, which is used to display the message path in the Management Console.
`\messagemodifier`	Not currently used for any purpose.
`\messagestore`	Holds both the message body, and all the metadata and properties of messages.
`\messagetables`	Contains indexes for the Hold Queue and Error Queue.
`\modules`	Contains all the uploaded modules, such as custom communication points and filters.
`\monitoring`	Contains a settings file used by the Management Console.
`\notifications`	Contains notifications history and respective indexes etc.
`\persistentmapstore`	Used by communication points to store values that must be persisted, for example, a database key value.
`\queue`	Stores index files that point into the message store. These indexes control how messages are queued inside the engine. The `\queue` data store includes the: Input Message Store. Output Message Store. Process Message Store. Redirected Message Store.
`\startup`	Stores the startup state information for a communication point or route. The storage location of the startup metadata can be changed by adding the `StartupService.directory` property to the `rhapsody.properties` file. If this directory is not present, it is automatically created.
`\statistics`	Stores statistical information used to plot graphs in the Management Console, and also the total message counts for components.
`\store`	Used as a general storage location.
`\tmp`	Used to store files temporarily as they are being processed by Rhapsody.
`\tracking`	Used to store information about messages currently being tracked.
`\transaction`	Contains a transaction system that operates in a similar way to a database.
`\users`	Contains all the user data. This data is protected with encryption and a one-way hash system so that it is impossible to recover a password. If the contents of this directory are deleted the administration account is automatically recreated.
`\validation`	Contains the current data validation status, which is used to ensure that data is validated correctly after an unclean shutdown.
