Best Practices For Deploying Java In Your Environment

Version 18


    Shavlik Protect users may encounter difficulties deploying Java. Most of these difficulties are casuse by Java being in use by having Internet Browsers, Programs that utilize Java or the Java Auto Updater Running at the time of deployment. This document walks through 3 recommendations on how to best avoid this.




    Recommendation 1.  - Disable the Java Auto Update Service by using an IT Script


    *Please first verify you have setup your environment for ITSCripts. Here are the requirements:

    On the second dropdown choose Disable Java Update Service.


    Click 'Run.' This will disable the Java Update Service on all selected Machines. This will stay disabled for new updates and new versions.

    Recommendation 2.  - Deploy Java with the Pre-deploy Reboot option selected in your Deployment Template


    This will eliminate the problem with programs in use during your Java deployment.


    Verify this by viewing your existing Deployment Templates by clicking Templates-My Deployment Templates.


    If you do not have a previous Deployment Template with the Pre-deploy Reboot option selected, you may create a new Deployment Template by clicking on New-Deployment template. By doing a Pre-deployment Reboot, this will ensure that no programs will be in use during the deployment.

    Recommendation 3.  - Disable the auto startup of any programs that utilize Java. (Advanced Users only)


    There are 2 ways to do this. Through Group Policy and on each machine. *NOTE changes to Group Policy or System Configuration can cause problems to your machines. This guide is for informational purposes only. Shavlik Protect Support won't support any problems caused from changes to the Group Policy or System Configuration.


    There are multiple places that startup applications are listed. See here for more information.


    Through Group Policy - See this document


    On Each Machine - You can Verify what programs are set to start on boot by using the System Configuration.

    Please read this article for more information.


    Open the System Configuration by typing msconfig in a run command and clicking OK.



    Next click on the startup tab. Uncheck any Programs that use Java. Click OK.




    The next screen will Prompt for a reboot. Please reboot before Java deployment.
