Installation

This page contains some important notes on installing the extension. Read the instructions for the replication extension closely.

The extension is available in the Public Application Repository. Installing the extension can be done with just a few clicks using the Package Manager. Install the latest "Messaging and Replication - Core" and "Messaging and Replication" (in this order).

Alternatively (e.g. when there is an corporate HTTP proxy involved requiring authorization - the Package Manager does not work in this case) the extension can be downloaded from the GitHub servers. This site contains always the latest and greatest versions of the XARs. On the GitHub page there is a change log available.

Important notes for the replication extension

Due to the design of the package manager, the Java class loader adds the JAR files to the class path in a relative late phases during the startup of eXist-db.

The 'listener' must be either configured in conf.xml as a StartupTrigger or can be started by calling an XQuery function (available since rev 0.7). This function can be started at database startup by using an XQueryStartupTrigger which can be enabled in conf.xml (available since eXist-db v2.2).

More information can be found on the Startup-Triggers page

For older versions of the extension (< v0.7) and eXist-db (<v2.2) the only option is to extract the JAR files from the XAR file manually into the lib/user directory.
