The Content Cache settings enable you to define cache size limits, minimum requirements for disk space, and the content retention period for content downloaded to ZENworks ondemand content servers and satellites with an Ondemand Content role. You can also specifically set how long metadata and content are maintained for downloaded files. See the descriptions below for more information about metadata and content:
Metadata: The "index" file that the Content Server uses to know what content to send to a device when it requests an update. The metadata needs to have a short Time-to-Live (TTL) so that the Content Server requests it frequently and has the latest index of content. Otherwise, it will continue to serve it to devices, resulting in devices not receiving the most recent content.
Content: The content pertains to what the Content Server is downloading and distributing to managed devices. For example, malware signatures and agent updates for devices that have the Antimalware Agent installed. The content should have a longer TTL so that it does not repeat downloads.
Patch Content: The Patch Content includes underlining patch binaries. The content should have a longer cache life so that it does not repeat downloads.
Patch Catalog: The Patch Catalog includes the actual signatures of the Patch. The content should have a longer cache life so that it does not repeat downloads.
Bundle, Policy and System Update: This includes all bundles, policies and system update content. The Cache Life setting is not applicable as the bundles, policies and system update content are available within ZENworks.The Remove Unused Content After setting is applicable only for the ondemand content that is downloaded from ZENworks ondemand content servers.
At the device level, if the Satellite Server is not updated to Update 3, then the Removed Unused Content After setting that was configured in Update 2, which is currently effective will be retained. This setting cannot be modified. After upgrading, the setting will be removed.
The Remove Unused Content After is applicable only for the ondemand content that is downloaded from the ZENworks ondemand content server.
To change the default or currently configured settings for the general cache, modify the fields directly for Cache Size, Disk Space, and Content Retention. To modify the settings for Cached File Time to Live, select Antimalware Metadata or Antimalware Content, and click Edit.
NOTE:If the configured Maximum Cache Size is lower than the content-repo size, then ondemand contents are not downloaded on the Ondemand Content Master (OCM) from an external source. If the metadata files are not available in the OCM, then the patch scan might not work as expected. Similarly, if the configured Minimum Free Disk Space is lower than the available disk space, then the new contents are not downloaded, and requests are rejected.
