Sun Java System Message Queue 4.3 Administration Guide

Configuring a File-Based Data Store

A file-based data store is automatically created when you create a broker instance. However, you can configure the data store using the properties described in File-Based Persistence Properties.

For example, by default, Message Queue performs asynchronous write operations to disk. However, to attain the highest reliability, you can set the broker property imq.persist.file.sync to write data synchronously instead. See Table 16–5.

When you start a broker instance, you can use the imqbrokerd command’s -- reset option to clear the file-based data store. For more information about this option and its suboptions, see Broker Utility.
