Users apply various patches to the existing Carbon server to enhance the available features or to fix possible bugs that may rise on the Carbon application. Applying patches thereby is an easy approach to use when existing executable JAR files need to be changed on the Carbon server.
To apply a kernel patch:
- Insert the required patches to the following directory:
$PRODUCT_HOME/repository/components/patches
Example:$ESB_HOME/repository/components/patches - Run
wso2server.sh -DapplyPatches
When running this patch the following is the sequence of actions that take place:- A backup folder named patch0000 gets created inside the
$directory containing the original content of thePRODUCT_HOME/repository/components/patches$folder. This step is executed as a precautionary measure so that if something goes wrong it is possible to revert to the previous state.PRODUCT_HOME/repository/components/plugins - The content of the patches directory will incrementally (e.g., patch0001, patch0002 etc.) get copied to the
pluginsdirectory.
This process is only supported for components which have already existing JAR files in the plug-in directory.
