Caplin Platform System Requirements
This page documents the hardware requirements and software dependencies of the Caplin Platform.
Hardware requirements
For help with capacity planning and choosing server hardware, see the following performance reports:
To ease log-file analysis across servers, time zones, and daylight savings transitions, we recommend that you set the system clocks of all hosts in a Caplin stack to UTC.
Software dependencies
This section lists the software dependencies of the Caplin Platform.

Java runtime environment
Caplin Platform deployments require a Java runtime environment (JRE) to run Java DataSources; Java modules in Liberator and Transformer; and JMX interfaces.
The most recent releases of Caplin Platform 7.1 components and libraries support the following JREs:
-
Red Hat OpenJDK 11
-
Red Hat OpenJDK 8
-
Oracle Java 8 (<= 8u202)
Releases of Oracle Java 8 after update 202 (8u202) require an Oracle licence for commercial use. Releases of the OpenJDK 8 after update 202 (8u202) remain free for commercial use. For more information, see the Oracle Java SE Licensing FAQ on the Oracle website.

Java application server
Caplin Platform’s KeyMaster Java is a single sign-on (SSO) solution that enables Liberator to delegate the act of authentication to a Java application server, such as Apache Tomcat.
Caplin web applications each include a KeyMaster servlet to provide seamless integration of Liberator with a bank’s authentication systems. For the hosting requirements of Caplin’s web applications, see the release notes for each web application.
The KeyMaster Java development kit includes example KeyMaster servlets that you can customise for your own web applications. For the hosting requirements of the example servlets, see the table below:
KeyMaster version | Servlet specification | Tested application servers |
