Initializing help system before first use

Prerequisites

Xpress Insight Server requires that some software be installed on your Linux system prior to installation.
The following must be installed:
  • Oracle or OpenJDK Java 8, 64-bit
  • PostgreSQL 9.5

    Xpress Insight Server only supports running against a database on the same machine.

On RHEL 6 or 7 you can install OpenJDK 1.8.0 using the system package manager. Xpress Insight Server can run with the OpenJDK headless package but you could alternatively use the full package that includes graphical components if necessary, java-1.8.0-openjdk :

yum install java-1.8.0-openjdk-headless

It is recommended to set the following environment variables before installation:
  • XPRESSDIR to point to the Xpress directory. The Xpress installer outputs instructions on how to set related environment variables.
  • JAVA_HOME set to point to your Java installation. If you have installed OpenJDK using the RHEL package manager then this should be set to point to the /usr directory.
  • If a custom data directory is used for PostgreSQL then set the PGDATA environment variable to point to this directory.
