Here are the recommended hardware and memory requirements for your in-house

Frevvoproduct
server.

Hardware Requirements

The minimum recommended hardware configuration for your Live Forms server is:

  • 2 gigahertz (GHz) 64-bit (x64) processor with 4 cores
  • 5 gigabyte (GB) of system memory
  • 100 GB hard drive

However you must size your hardware platform to your specific form usage characteristics. As the number of concurrent users and forms/flows increases so must the system memory. For a medium use production server consider increasing the JVM RAM allocation to 6 or 8 gigabytes. Refer to the memory configuration topic below.

Memory Configuration

The

Frevvoproduct
 Tomcat bundle comes pre-configured with default memory usage settings. While the defaults are sufficient for initial usage, as your forms, business logic and submissions grow, so will the memory needs of the
Frevvoproduct
  server.

Code Block
languagebash
set JAVA_OPTS=-Xms128m -Xmx512m -Djava.awt.headless=true
-Dfrevvo.users.path="%CATALINA_HOME%\..\data\users"

Live Forms as a windows service

If you are running

Frevvoproduct
 as a Windows service, you will have to edit frevvo/tomcat/bin/service.bat line to increase the Java Heap and Permgen spaces. Here is an example of the line you need to edit in that file:

Code Block
languagebash
"%EXECUTABLE%" //US//%SERVICE_NAME% ++JvmOptions "-XX:MaxPermSize=128m 
-Djava.io.tmpdir=%CATALINA_BASE%\temp;
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager;
-Djava.util.logging.config.file=%CATALINA_BASE%\conf\logging.properties" 
--JvmMs 128 --JvmMx 512

See the documentation on Tomcat Windows Service for more details.

After making these modifications to the service.bat file, you must Remove/Reinstall Live Forms as a Windows service for the changes to take effect.

Insight Server Memory Settings

By default, the <frevvo-home>\solr-5.4.1\bin\solr script,sets the maximum Java heap size to 512M (-Xmx512m). This may not be sufficient especially when reporting on/indexing a large number of submissions. It may cause "out of memory" exceptions in the  <frevvo-home>solr-5.4.1\server\logs\solr.log file. The JVM heap size can be increased to resolve this. Make sure that the machine where the Insight Server is installed has enough memory to accommodate your changes.
