The patch.jar for the ConfigManager and Master Controller is uploaded via the Admin Interface.  The patch for the OC / FSS can be placed under the name patch.jar in the region home folder of the oc / fss and specifically listed in the client config xml under <otherRootConfigFiles>. It is common to distribute the patch.jar using the ConfigManager as a RootConfigFile. When the ConfigManager is used to upload a new patch.jar, the patch.jar in the the OC and FSS will replace the file in their region home by the new file from the database. When it is necessary to control the fss and oc patches separately, a prefix fss_ or oc_ or any other prefix can be used (e.g. fss_patch.jar or oc_patch.jar) as long as the last part is patch.jar. The prefix is optional.
