8.0 Troubleshooting System Updates

The following sections provide solutions to the problems you might encounter while performing a system update:

Deleting the superseded files

Source: ZENworks 11.2 or later
Explanation: When you install a newer version of ZENworks, the older version file or package will be retained in the following location:

  • Windows: %ZENWORKS_HOME%\install\downloads

  • Linux: /opt/novell/zenworks/install/downloads

The retained file or package names will have superseded as a suffix.

For example, novell-zenworks-primary-agent-langs-client-11.2.1.6268.msi.superceded

These superseded files allow you to enable the older version components that are disabled after updating. These files might not be deleted even after deleting the system update from the zone. The superseded files are deleted automatically when the update is base-lined.

Action: To delete the superseded files manually, consider the following scenarios:

  • If all agents are upgraded to a newer version.

  • If the Managed Zone does not have agents in that specific version of the update.

  • If the standalone install feature is not used.

  • If you are absolutely certain that components from the older version agent are not needed.

System update fails on a Windows 10 device

Source: ZENworks 2017, System Update
Explanation: During the system update of a Windows 10 device, the update to ZENworks 2017 Update 1 fails, which is indicated in the ZCC > Configuration > System Updates page.

Action: Click the Status link in the Deploying System Updates panel on the System Updates page, and follow the instructions* to restart the System Update:

*This update cannot continue as at least one of first two service recovery failure modes for ZES service is set to restart the computer. Please disable client self defense, reboot the device, and restart the ZENworks Update.

System update hangs

Source: ZENworks, System Update
Explanation: While importing the system update into the Zone, if the database restarts, the download progress gets stuck.
Possible Cause: During the download process, the ZENworks Loader module downloads the update and updates the database with information related to the download progress. ZENworks Control Center reads this information from the database and displays the download progress. If the database restarts in between, the communication between the ZENworks Control Center Service, the Loader module, and the database is interrupted. If the download is still in progress when the database restarts, the download status gets stuck.
Action: Cancel the download which is in progress and re-initiate it again.

OR

Delete the update and download it again.

System update of a Windows device fails because the ZENUpdater.exe executable crashes

Source: ZENworks, System Update
Explanation: During the system update of a Windows device, the ZENUpdater.exe executable crashes, and the system update fails.
Possible Cause: The ZENUpdater crashes because the .NET 4.0 framework has not been installed successfully.
Action: Verify that the .NET 4.0 framework is properly installed on the device. Re-install the .NET 4.0 framework if necessary. Restart ZENUpdater.

An administrator with System Update Deploy right and device level View Leaf right is unable to create the first stage

Source: ZENworks, System Update
Explanation: In ZENworks Control Center, the administrator with System Update Deploy right and device level View Leaf right on the entire zone is unable to create the first stage.
Action: The administrator with System Update Deploy right and device level View Leaf right on the entire zone should create a stage only after the super administrator has created the first stage.

Source: ZENworks, System Update
Explanation: After System update is completed, two ZENworks icons are displayed on a Mac agent.
Action: You must re-login or restart the device.

Unable to get updates when you perform the Check For Updates action

Source: ZENworks, System Update
Explanation: In ZENworks Control Center when you perform the Check For Updates action, there might be a failure.
Possible Cause: The Novell Customer Center (NCC) server displays a warning that the system update entitlement has expired even when that is not the case.
Action: Initiate the Check for Updates process in the background.

  • Click OK in the Retry Check for Updates dialog when you are prompted to initiate the Check For Updates process in the background. For more information, see the Section 2.2.2, Manually Checking for Updates.

    The check for updates process, which is initiated in the background, uses the values configured for the following fields in the SUEntitlementConf.properties file:

    • retryCount-CheckForUpdates

    • sleepInterval-CheckForUpdates

http-nio CLOSE_WAIT clear connection default value is set to 1 hour

Source: ZENworks, System Update
Possible Cause: On a 11 SP4 ZENworks Server, the agent ZeUS service opens a single http-nio connection with port 80. This connection will continue to be in CLOSE_WAIT state on the server even after agent ZeUS service is stopped.
Explanation: This behavior is normal as the default close time for this connection is set to a maximum of one hour. The default value of the ZeUS configurable parameter, notifier-socket-timeout, is set to 3600000. The parameter is available in the \ZeUS\Conf\zeus.conf configuration file and the default value of the parameter can be configured between 5 minutes and 1 hour.
Action: On the servers, you will see many such connections opened from multiple devices in the zone. You can ignore these CLOSE_WAIT connections as they will be cleaned up in an hour. The maximum number of connections that can be opened to this http-nio port is 20000.

Permission prompt not getting displayed on Embedded win 7 device

Source: ZENworks, System Update
Possible Cause: This is the default behavior of Windows 7 embedded device.
Explanation: The default behavior of Windows 7 embedded device could not be changed from ZENworks as MessageBox API provided by user32.dll is used.
Action: In the Windows registry, set the value of the Enabling Default Reply registry key to 0. This will disable the auto reply on prompts. The folder path of the registry key is HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\. For more information, refer to the MSDN solution.

ZeUS service does not working properly when a Satellite Server is demoted and then the device is updated without a reboot

Source: ZENworks, System Update
Explanation: When you demote a Satellite Server and then update the device without performing a reboot, the ZeUS service will not work properly because the rt.jar file is missing.
Action: Run the msiexec -i <filePath> TARGETDIR="<default agent installation path>" REBOOT=ReallySuppress ALLUSERS=1 /lvx*+ <log_file_path> " /qn command to generate the rt.jar file again.

In this command:

  • <filePath> is the location of the novell-zenworks-jre msi file.

  • <default agent installation path> is the location where the agent is installed.

  • <log_file_path> is the location where you want to create the log file.

Example: msiexec -i "C:\Program Files (x86)\Novell\ZENworks\cache\zmd\ZenCache\fb739230-e0de-4460-a2d2-cc1dfe1b4613\novell-zenworks-jre-1.7.0_80.x86_64.msi" TARGETDIR="C:\Program Files (x86)" REBOOT=ReallySuppress ALLUSERS=1 /lvx*+ "C:\Program Files (x86)\Novell\ZENworks\logs\system-update\5011040000fc50000000002015061004\novell-zenworks-jre-1.7.0_80.x86_64.msi.log" /qn

Source: ZENworks, System Update
Explanation: On SLES servers, after performing a system update the ZENworks services are not restarted automatically. Even if you manually restart the services, they stop after a couple of minutes.
Action: Restart ZeUS.
