WHD installation requirements

This section describes the requirements for setting up a WHD deployment in a stand-alone or Orion Platform deployment.

If you plan to enable Federal Information Processing Standard (FIPS) 140-2 compliant cryptography in your deployment, see the WHD Administrator Guide for specific requirements.

Server sizing requirements

Determine the requirements for your Web Help Desk deployment size.

Deployments with fewer than 20 techs

If you plan to support 20 tech sessions or fewer in your deployment, you can run WHD on a system with:

  • A supported operating system
  • A 32-bit Java Virtual Machine (JVM)
  • 4GB RAM (up to 3.7GB for the tech sessions, JVM support, operating system, and any additional services you need to run on the system)

This configuration supports 10 - 20 tech sessions with no onboard memory issues.

To adjust the maximum memory setting, edit the MAXIMUM_MEMORY option in the WebHelpDesk/conf/whd.conf file.

Deployments with more than 20 techs

If you plan to support more than 20 tech sessions in your deployment, SolarWinds recommends installing WHD on a system running:

  • A supported operating system
  • A 64-bit JVM
  • 3GB RAM for 20 tech sessions plus 1GB RAM for each additional 10 tech sessions

Configure the JVM memory allocation

Calculate the amount of memory required for your JVM and increase the allocation as required.

Database requirements

WHD uses an embedded PostgreSQL database as its standard database. The following table lists the supported databases for WHD.

Database Supported versions

PostgreSQL 9.2

PostgreSQL 9.3.2

PostgreSQL 9.4

PostgreSQL 9.6

PostgreSQL 13.3


MySQL 5.7

Microsoft SQL Server

SQL Server 2008 R2 SP3

SQL Server 2012 SP2

SQL Server 2014

SQL Server 2016

SQL Server 2017

For optimal external database performance, run WHD and a supported external database on separate servers.

Database hardware requirements

The following table lists the minimum hardware requirements for a database server running Microsoft SQL Server or MySQL with WHD.

Component Requirements
CPU 64-bit Dual Core 3.0 GHz or higher
Hard drive space 20 GB
RAM 3 GB with 1 GB additional RAM for every additional 10 techs

External database options

WHD supports SQL Server 2008, SQL Server 2014, and MySQL 5.7 as external databases. You can also use an external PostgreSQL 9.2 or PostgreSQL 9.3 database with WHD 12.6 and later.

See Database datatypes for information about mapping information types across other databases types.

Oracle Java Database Connectivity (JDBC) driver requirements

WHD for macOS includes an embedded Java Virtual Machine (JVM). If you are running an external Oracle JVM, WHD preserves your Java settings during the installation procedure and continues to use the external Oracle JVM.

If you are migrating from an external JVM to the embedded JVM included with WHD and you are using a MySQL database, ensure that the new embedded Java directory on your Web Help Desk server includes the Oracle Java Database Connectivity (JDBC) driver.

See Install the MySQL JDBC Driver in the WHD Administrator Guide for instructions.
