Use the Server.xml configuration file to configure the topic persistence feature.
-
Edit this section of the etc/Server.xml file to configure
persistence.
<persistence enabled="false">
<!--
<store-directory>dirName</store-directory>
-->
</persistence>
- In the persistence element, set the
enabled property to true to enable
persistence. Removing the enabled property will also enable persistence.
- By default, log files will be created in a directory called
persistence in the
Diffusion™
Cloud
installation directory.
If you want to use a different directory, uncomment the store-directory element
and enter the full path to the directory where you want the files to be stored.
-
Restart the
Diffusion
Cloud
server to load the
configuration.
Enabling persistence creates log files which can use a significant amount of file storage. Make sure
to monitor the amount of space available in the server file system. See Topic persistence
for information about the approximate storage requirements.
If you want to back up or restore the persistence log, you should stop the
Diffusion
Cloud
server.
When enabled, persistence is applied to all topics by default. You can disable persistence for an individual topic using the
PERSISTENT topic property.
