Browsers

LabKey Server requires a modern browser for many advanced features, and we recommend upgrading your browser(s) to the latest stable release. As a general rule, LabKey Server supports the latest version of the following browsers:

If you experience a problem with a supported browser feel free to search for, and if not found, post the details to the support forum so we're made aware of the issue.

Java

We recommend using the latest point release of AdoptOpenJDK 15 64-bit (x64) with HotSpot JVM (currently 15.0.2+7), the community-supported production-ready distribution of the Java Development Kit.

LabKey 20.11.x and 21.3.x have both been tested with the recent JDK 16 release, however, you must run the Java 16 JVM with two special flags --add-opens=java.base/java.lang=ALL-UNNAMED --add-opens=java.base/java.io=ALL-UNNAMED to allow certain libraries to function properly. (Note that standard startup scripts in the most recent Tomcat versions add these flags automatically.) And you can't currently build using JDK 16 because Gradle, our build tool, doesn't yet support it. We will upgrade the libraries and Gradle as soon as they fully support JDK 16.

LabKey continues to support Oracle OpenJDK, Oracle's open-source build of the JDK, and AdoptOpenJDK 14 with HotSpot JVM, though note that public updates (i.e., patches to address security and reliability issues) are no longer provided for JDK 14.

LabKey Server has not been tested with other Java distributions such as the Oracle commercial Java SE, Amazon Corretto, Red Hat, Zulu, OpenJ9, etc.

Apache Tomcat

We recommend using the latest point release of Apache Tomcat 9.0.x (currently 9.0.45).

LabKey continues to support older version 8.5.x, though we strongly recommend installing the latest point release (currently 8.5.65); older point releases have major compatibility issues and security vulnerabilities. Support for Tomcat 7.0.x has been removed since this version has reached end-of-life. LabKey does not support Tomcat 10.0.x.

We recommend installing Tomcat using the binary distributions; if a package manager is used, the lib directory may be installed in a different location. Also, the packages sometimes include alternative versions of some components (like JDBC connection pools) that can cause incompatibilities.

We recommend not using the Apache Tomcat Native library; this library can interfere with SSL and prevent server access via LabKey's client libraries.

PostgreSQL

For installations using PostgreSQL as the primary database, we recommend using the latest point release of PostgreSQL 13.x (currently 13.2).

For those who can't transition to 13.x yet, LabKey continues to support PostgreSQL 12.x, 11.x, 10.x, 9.6.x, and 9.5.x, though here also we strongly recommend installing the latest point release (currently 12.6, 11.11, 10.16, 9.6.21, and 9.5.25) to ensure you have all the latest security, reliability, and performance fixes.

PostgreSQL provides instructions for how to upgrade your installation, including moving your existing data.

Microsoft SQL Server (Premium Feature)

Premium Editions of LabKey Server have the option of using Microsoft SQL Server databases as the primary database and as external data sources. For these installations, we recommend using Microsoft SQL Server 2019 , which we've tested on both Windows and Linux.

LabKey continues to support SQL Server 2017, 2016, 2014, and 2012. LabKey does not support SQL Server 2008 R2 or earlier releases.
