Anti-virus Requirements

We recommend you disable any anti-virus or firewall software (including Windows firewall) installed on the Snaplex node. If you cannot disable the software, then ensure that the Snaplex process is not scanned by the anti-virus. The specific action depends on the antivirus software type and scanning rules enabled. The following are the guidelines:

• Disable the network firewall functionality for the following ports: 8081, 8084, 8089, and 8090. See the Required Ports section below for more information about workarounds for other applications using the required ports.
• Disable filesystem scanning for the c:\opt\snaplogic folder.
• Disable process-level scanning for the SnapLogic service.

Required Ports

If another application already uses one of the JCC ports used by SnapLogic, the JCC nodes do not complete a full start cycle. The workaround is to override the default port by assigning the following entries in the global.properties file to ports that are available:

• For HTTP port: jcc.jetty_port = 8x89

• For HTTPS port: jcc.cc_secure_port = 8x81

Java Development Kit (JDK)

You must install the Java Development Kit (JDK) before installing your on-premise Snaplex. The SnapLogic platform supports Java 11. We recommend you use the latest patch version available of Java 11 for your Windows environment. To update your Snaplex to the Java 11, see Upgrading Your Groundplex to Java 11.

File Name Length

File names generated by SnapLogic for suggest data can be longer than 260 characters long. We recommended that you configure the Snaplex node to allow longer file paths. See Maximum Path Length Limitation - Win32 apps for details.

Installing the Snaplex

1. As an Org admin, log into SnapLogic Manager.
   
   
2. Under Project Spaces on the left, locate the project where you want to create your Groundplex (or the global shared project), then select the Snaplexes tab on the right.
   
   
   
3. Click the Create + button and complete the Create Snaplex dialog (later known as the Update Snaplex dialog). 
   
   
   
4. Once completed, the dialog reopens to the Downloads panel.
   
5. Download the Windows ZIP file and the configuration file onto the Windows machine where you want the Groundplex installed.
   
   
6. Create the directory \opt on your server in the root of the C: drive.
   
   
7. Unzip the zip file to c:\opt. This will create a directory c:\opt\snaplogic and a directory structure as follows:
   
   
   

8. Check your Windows environment to see if you have a version 11 of Java.

   Version of Java

   Make sure the version of Java that you are installing matches the type (32-bit or 64-bit) of Windows machine.

   
   Do this by executing the command java -version in a command window.
   
   
   

   1. If the version of Java is less than JDK 11, download the Windows JDK and install the JDK at c:\opt\java.
      
      
   2. If JRE 11 is already available on the machine, the existing installation can be used. Use Notepad to edit the file c:\opt\Snaplogic\bin\jcc.bat and change the entry for the JAVA_HOME environment variable to the location of the existing installation, putting double quotes around the value.
      
      
      
   3. If the host machine is configured for JDK auto-update, then each time a JDK update occurs, the older JRE installation is deleted by default. As a result, the Snaplex fails to start after the JDK update. To avoid this issue, use the static installation feature of the JDK installer.  
      To do a static install:
      • Add the STATIC=1 option when running the JDK installer from the command line or from the Run dialog.
      • When the JRE auto-update occurs, uncheck the uninstall option for older JDK installations. This prevents the older installation from being removed. 
        
        
9. After the software has been installed, place the downloaded configuration file in the \opt\snaplogic\etc directory and make sure the file name ends with .slpropz.
   
   
10. From the command prompt, change to the \opt\snaplogic\bin directory. You may start the node by running the command: jcc.bat start

    
    Alternatively, to install the Snaplex as a Windows service, run the following command as an administrator: jcc.bat install_service.
    
    Then, go to the Windows Control Panel services, to view the entry for the SnapLogic Snaplex, and start the service from Tools in the Services window.


11. To establish if the process started, run the command: jcc.bat status. The state should be Running.
    
    

12. To verify the Snaplex has started, visit https://elastic.snaplogic.com/sl/dashboard.html#Health
    The newly installed node should show up in the list of nodes for the Snaplex.
    

Upgrading on Windows

Updating Cygwin Binaries

jcc.enable_auto_download = False

Troubleshooting Installation

• Are you starting the JCC node as an administrator?
• Is the c:\opt\snaplogic\run\log folder full? If it is full, delete the logs and try restarting again.
• Is JAVA_HOME set correctly?

In a Snaplex installation on a Windows machine, you need to install the JRE and configure the JRE location in the jcc.bat property. While a Snaplex auto upgrade updates the SnapLogic binaries in the installed Snaplex, the JRE version is not automatically updated. You must manage the JRE version in your self-managed Snaplex.

Uninstall the SnapLogic RPM from your environment

To uninstall the SnapLogic Windows-based package from your environment:

1. Stop the Snaplex service before uninstalling or installing the Snaplex elsewhere by using the following command.
   run bin\jcc.bat stop.

2. If Snaplex is installed as a service, the service needs to be removed by running the command.
   bin\jcc.bat remove_service.

3. Clean up the directory \opt on your server in the root of the C: drive.
   
   

   

Older Versions of JRE and TLS

JRE versions prior to 11.0.8 have issues connecting to TLS 1.3 endpoints. We recommend using a newer JRE version.

Renabling Support for Older Versions

If updating the TLS endpoint is not possible, then the Snaplex JRE can be updated to re-enable support for older TLS versions by doing these steps:

1. Open the jre/conf/security/java.security file in the JRE installation folder that you configured during installation.

2. Change the jdk.tls.disabledAlgorithms configuration property by removing TLSv1, TLSv1.1.

3. Restart the Snaplex to re-enable support for TLS 1.0 and 1.1.
