Preparing the host machine

Perform the following steps before you deploy NexJ Model Server:

1. Create the root directory in which to deploy the server instance or cluster, for example, D:\nexj\modeld. 
2. Review the prerequisites listed in Prerequisites and supported platforms in the NexJ CRM Release Notes.

3. Install Java JDK 8 or later and set the system environment variable JAVA_HOME to the Java JDK installation directory.

4. Acquire the database driver for communication between Model Server and your database server.

   For more information, see Required database drivers in the NexJ CRM Release Notes.

5. If using a multiple-node environment with Model Server working behind a web server such as Apache or IIS, configure load balancing. For more information, see Configuring load balancing for Model Server.

6. If deploying on Linux, install the Arial font, required by predefined reports. For example, copy the font to: <JAVA_HOME>/jre/lib/fonts. You must install the Arial.ttf font file for each JVM on the application server machine and then restart each JVM. Arial is owned by Monotype.

7. Recommended: Configure OS TCP keep-alive and retries. For more information, see Configuring TCP on Model Server.
