Beginning in ZENworks 2020 Update 3, Patch Management enhancements incorporate ondemand patching of devices. In principle, this means that patches required by managed devices are not downloaded to Content servers until they are requested by the device. However, there are options that you can configure to pre-fetch patch content from external sources before the patches are requested by devices. You can also configure pre-cache settings to replicate patches to specified Content servers once they are downloaded by an Ondemand Content Master. These settings are described in Configuring Pre-Cached Content.
Pre-fetch settings are described below. To access the settings in ZENworks Control Center, navigate to Configuration > Management Zone Settings > Security > Patch Pre-Fetch Settings.
For additional information about pre-fetching content, see Understanding Pre-Fetching and Pre-Caching of Patches.
Each pre-fetch option is described below:
Manual “Update Cache” action: This option is selected by default. When enabled, a patch is not downloaded by an Ondemand Content Master until the first device that needs it requests it or you select the patch in the Patches page and run Update Cache from the action menu.
Patch policy rebuild: When enabled, this option will pre-fetch patches required by devices that meet the patch policy criteria upon policy rebuild.
Patch remediation deployment: When enabled, this option will pre-fetch patch content applicable to remediation deployments, so the content is already fetched when requested by devices.
With ondemand patching, the required patch language is included with the patch request from the managed device. However, if you pre-fetch patches before a device requests them, the language must be specified. Use the Languages panel to select the patch language or languages required when enabling any of the pre-fetch actions.
