Hardware Requirements

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

...

However you must size your hardware platform to your specific form usage characteristics. As the number of concurrent users and forms 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  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   server.

...

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

Troubleshooting

Solutions for memory errors are discussed below:

OutOfMemoryError: Java heap space

SEVERE: Servlet.service() for servlet jsp threw exception
java.lang.OutOfMemoryError: Java heap space

...

For example: -Xmx512m to -Xmx1g. Make sure also that the machine where  is installed has enough memory installed. If you change -Xmx to 1g your machine will need more then 1g ram.

OutOfMemoryError: PermGen space

MemoryError: PermGen space
java.lang.OutOfMemoryError: PermGen space

...

For example: -XX:MaxPermSize=128M

IP Addresses

The IP address for http://app.frevvo.com/ (frevvo cloud server) is 54.86.85.105. Customers that use firewall white listing for  http://app.frevvo.com/ must add this IP address to their white list . This is applicable for outgoing HTTP POSTs to connectors. For example if your forms are posting to the frevvo database connector or any other connector you installed behind your company firewall.

 The IP address for www.frevvo.com and app.frevvo.com is 54.86.98.4. Customers do not need to take any action as this is handled by the DNS entry automatically.
