Chapter 2. Patching Existing Server Instances
Since new micro releases of JBoss Data Grid server do not completely replace the existing installation, they are released as a patch for your convenience. 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 procedure used to patch 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 7.0.1 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
$JDG_HOME/bin/cli.sh --connect=127.0.0.1:9999Copy to Clipboard Copied! Toggle word wrap Toggle overflow - Ensure there are no active connections to the server, and then apply the patch:
patch apply /path/to/jboss-datagrid-7.0.1-server-patch.zip
patch apply /path/to/jboss-datagrid-7.0.1-server-patch.zipCopy to Clipboard Copied! Toggle word wrap Toggle overflow - Restart the server:
shutdown --restart=true
shutdown --restart=trueCopy to Clipboard Copied! Toggle word wrap Toggle overflow
All other files, such as EAP modules, clients, and the standalone library mode version of JBoss Data Grid, are provided as full archives. Due to this there is no possibility to patch these files.
