## Evaluation Server

The default installation of CloverETL Server uses the embedded Apache Derby DB; therefore, it does not require any extra database server. Furthermore, it does not require any subsequent configuration, as CloverETL Server configures itself during the first startup. Database tables and some necessary records are automatically created on the first startup with an empty database.

By performing a subsequent configuration, you can evaluate other CloverETL Server features (e.g. sending e-mails, LDAP authentication, clustering, etc.). This way, you can also prepare the evaluation server for production environment. However, note that the embedded Apache Derby database is not recommended for production environment. Therefore, before the subsequent configuration, choose one of the supported external dedicated database.

If the CloverETL Server must be evaluated on application containers other than Tomcat, or you prefer a different database, proceed with the common installation of Production Server

### Installation

1. Make sure you have a compatible Java version:

   | Important
   CloverETL Server 4.1 and higher requires Oracle JDK or JRE v. 1.7.x or higher. We recommend JDK 1.8.x.

   - You can check your installed Java version by typing the following command to the command prompt or terminal:

         java -version

   - Alternatively, for macOS and Windows platforms, see How to find Java version in Windows or Mac.

2. Download and extract the CloverETL Evaluation Server.

   - Go to CloverETL User Login Page.

   - Using your credentials, log into your account, navigate to the download section and download the CloverETL Evaluation Server Bundle.

   - Extract the `.zip` archive. (For example, the name of an archive containing `CloverETL Server v 4.5.0` bundled with `Tomcat v 8.0.30` will be `CloverETLServer.4.5.0.Tomcat-8.0.30.zip`.)

   | Note
   It is recommended to place the extracted content on a path that does not contain space character(s). `C:\Program Files` or `/home/user/some dir` `C:\Users\Username` or `/home/user/some_dir`

3. Set the `JAVA_HOME` or `JRE_HOME` Environment Variables.

   - Unix-like systems:

     - Using a text editor, open the `setenv.sh` file located in the `[Tomcat_home]/bin/` directory.

     - Define the path at the beginning of the file (the path may differ):

           export JAVA_HOME=/usr/jdk1.8.0_121

       Figure 3.1. `setenv.sh` edited in Linux.

   - Windows system:

     - Using a text editor, open the `setenv.bat` file located in the `[Tomcat_home]\bin\` directory.

     - Define the path on the second line of the file (the path may differ):

           set JAVA_HOME="C:\java\jdk1.8.0"

       Figure 3.2. `setenv.bat` edited in Windows.

4. Run Tomcat.

   - Unix-like systems:

     Run the `[Tomcat_home]/bin/startup.sh` file.

   - Windows system:

     Run the `[Tomcat_home]\bin\startup.bat` file.

5. Check whether CloverETL Server is running.

   - Open a new tab in your browser and type http://localhost:8083/clover/ in the address bar.

   - Use the default administrator credentials to access the web GUI: username: clover, password: clover.

     | Note
     If you access the web GUI of the CloverETL Server before the product activation, you will be asked to install the CloverETL Server license key. Continue with: CloverETL Server Activation

     | Tip
     To safely stop the server, run the `[Tomcat_home]/bin/shutdown.sh` or `[Tomcat_home]\bin\shutdown.bat` file for Unix-like or Windows system respectively.

6. CloverETL Server is now installed and prepared for basic evaluation. There are couple of sandboxes with various demo transformations installed.
