Chapter 2. Patching Existing Server Instances
Micro releases for the JBoss Data Grid server are distributed as a patch. This is for your convenience, as the new version will not completely replace the installation. The base version to be patched is the x.y.0 release, and the patches x.y.# (micro release or cumulative patch) may be applied to that instance. The patch can be rolled back (including the configuration) if there is any issue during the patching process, and any subsequent patches may be applied in the same way.
This process is similar to the already known procedure in JBoss Enterprise Application Platform (EAP).
Note
It is strongly recommended to back up your existing installation, including all configuration files, before applying the patch.
Procedure 2.1. Applying the JBoss Data Grid 6.6.2 Patch
- Download the patch from the Red Hat Customer Portal at https://access.redhat.com/downloads/
- Connect to the running instance to be patched using the JBoss CLI:
$JDG_HOME/bin/cli.sh --connect=127.0.0.1:9999
- Ensure that there are no active connections to the server, and then apply the patch:
patch apply /path/to/jboss-datagrid-6.6.2-server-patch.zip
- Restart the server:
shutdown --restart=true
All other distributions, such as the EAP modules, client's, and standalone library mode are provided as a full release. Due to this there is no possibility to patch existing archives for these distributions.
