Caplin Platform System Requirements

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.
