1 Installing patches
Java patches:
sudo -u node -s mkdir -p /Node/tomcat/shared/classes cd /Node/tomcat/shared/classes cp patch.jar /Node/tomcat/shared/classes /Node/java/bin/jar xf patch.jar
Before doing a GCN update, any patches should be removed, unless you are absolutely sure that it is compatible with the new version. Patched GCN installations are not supported by Gentics, unless given by Gentics support.
2 Removing patches

rm -fR /Node/tomcat/shared/classes/*
PHP patches will be overwritten automatically when updating.
