33.1 Configuring Content Replication at the Management Zone Level

  1. In ZENworks Control Center, click the Configuration tab.

  2. In the Management Zone Settings panel, click Content > Content Replication.

  3. Fill in the fields:

    Primary Server Recurring Content Replication Schedule: Use the Days, Hours, and Minutes fields to set the schedule.

    You can use any combination of the fields. For example, to specify every 30 hours, you can enter 30 hours or 1 day, 6 hours.

    NOTE:

    • We recommend you to set the schedule to 12 hours.

    • If a Satellite device is at the end of a very slow link (for example, a 128K WAN), you might want to disable the content replication schedule so that content can be manually replicated by using the zac wake-cdp (cdp) command. For more information about the zac wake-cdp command, see Content Distribution Commands in the ZENworks Command Line Utilities Reference.

      To disable the content replication schedule on a Satellite device set the Schedule Type to No Schedule. For more information on setting the schedule type, see Understanding the Content Role.

    Primary Server Output Throttling in KB/Sec: Select the throttling rate you want to use.

    This rate applies to all ZENworks Servers in your zone. You cannot set individual throttling rates.

    The content replication throttling rate determines the maximum amount of content (in kilobytes per second) that a ZENworks Server transfers when replicating content to other content servers or when distributing content to managed devices.

    By default, no throttling rate is imposed, which means that a ZENworks Server uses all available bandwidth.

    Agent Content Checksum: Specify whether the ZENworks Agent on managed devices computes the checksum of downloaded content and compares that checksum to the stored checksum for that content on the ZENworks Primary Server.

    Comparing checksums helps to ensure that no errors were introduced during the downloading of the content and that the content was not altered.

    Under normal conditions, you should use the default of On. If your ZENworks System has serious performance issues, you can set this setting to Off to increase performance.

    Satellite Content Checksum: Specify whether the ZENworks Agent on Satellite devices computes the checksum of downloaded content and compares that checksum to the stored checksum for that content on the ZENworks Primary Server.

    Comparing checksums helps to ensure that no errors were introduced during content replication and that the content was not altered.

    Under normal conditions, you should use the default of On. If your ZENworks System has serious performance issues, you can set this setting to Off to increase performance.

  4. Click Apply or OK to save the changes.

33.1.1 Manually Configuring the Web Service Timeout Advanced Content Replication Setting

You can adjust the Web Service Timeout value to suit your needs. For example, if a Satellite device is across a slow WAN link and there is missing content, the default 240-second timeout value might not be long enough to make the Web service call.

To modify the Web Service Timeout on a Satellite device:

For Windows, create the following string value in the registry on the Satellite device:

HKEY-LOCAL-MACHINE\SOFTWARE\Novell\ZCM\CDPWebCallWaitTimeout and set the value to the desired number of milliseconds.

For Linux, in the /etc/opt/novell/zenworks/conf/xplatzmd.properties file on the Satellite device, add the following line:

CDPWebCallWaitTimeout=xxx

where xxx is the desired timeout value in milliseconds.
