Prerequisites
Xpress Insight Server requires that some software be installed on your Red Hat Enterprise Linux (RHEL) system prior to installation. A valid Xpress license is required to install
Xpress Insight Server.
The following must be installed:
- Java 11 is required. The following builds are supported:
- Oracle Java 11 64bit Hotspot. Minimum version 11.0.2. We recommend the latest version 11 update.
- OpenJDK 11 64bit Hotspot. Minimum version 11.0.2. We recommend the latest version 11 update.
- PostgreSQL 9.5
Xpress Insight Server only supports running against a database on the same machine.
On RHEL 6 you will require Oracle Java 11 with the appropriate licensing and support levels in place. On RHEL 7 you can install OpenJDK 11 using the system package manager. Xpress Insight Server can run with the OpenJDK headless package, for example on RHEL 7.6:
yum install java-11-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.
