Installation Steps

To install NetVizura on Windows follow these steps:

Step 1: Download and install Oracle Java 8 from Oracle official website www.oracle.com/technetwork/java/javase/downloads/index.html , or if you don't have support agreement with Oracle,you can download openJDK build from :https://github.com/ojdkbuild/ojdkbuild . In openJDK case,you should download .msi file eg. https://github.com/ojdkbuild/ojdkbuild/releases/download/1.8.0.212-1/java-1.8.0-openjdk-1.8.0.212-1.b04.ojdkbuild.windows.x86_64.msi  .

Only 64-bit Java is supported, so choose Windows x64 installer. We recommend JDK package because it helps with troubleshooting.

Step 2: Download and install Tomcat 7 (or higher- 9 (Tomcat 10 is not supported currently) as a service from Tomcat official website website tomcat.apache.org. 32-bit/64-bit Windows Service Installer is available on the downloads page.

When prompted for the installation type, choose Full installation. This will enable Tomcat to start on boot.

Post Install Steps

After installation tweaking of configuration files is required in order to utilize the installed RAM to the fullest extent. The main consumers of RAM are operating system, PostgreSQL database and Tomcat. General rule for distributing memory is to split it in ratio 2:1 between PostgreSQL and Tomcat with 1 GB or more reserved for operating system. For instance:

Tweaking PostgreSQL

Tweaking PostgreSQL for best performance is a topic on which many books were written, but the following are some common sense suggestions. For the curious ones recommended reads (among countless others) are PostgreSQL Optimization Guide,  and PostgreSQL Tuning Guide, this article and this book.

In order to apply following tweaks edit file postgresql.conf, this file is usually located in PostgreSQL data folder. You will need to restart the PostgreSQL service after done editing. Almost all of the following parameters are commented with carron character (#). Be aware that if you comment out the parameter that has been changed, PostgreSQL will revert to the default value. 

Elasticsearch Memory Optimization

 By default,we set memory limit for Elasticsearch to 30% of RAM. If you need to set it to any other value, edit the file: /etc/elasticsearch/jvm.options and set values -Xms and Xmx to desired size. After that restart the Elasticsearch and Tomcat services.

Tomcat Memory Allocation 

During installation NetVizura automatically allocates memory for Tomcat process. The amount allocated to Tomcat process is calculated according to the formula:

(RAMtotal - 1GB) / 3 but no less than 1GB.

For instance:

However, if you need to tweak Tomcat RAM allocation differently (the example for 2048MB):

1. Double click on Apache Tomcat Properties in system tray
   
   
   
   
2. In Java tab under Java options modify the -Xmx parameter to allocate additional memory to Tomcat. Additionally, set parameter -Xms to the same amount. Also set Initial memory pool and Maximum memory pool to the same amount. This should look like on picture below.
   
   

3. Back to the General tab, click Stop and Start to restart Tomcat.
