Server sizing requirements

Use the following sections to determine the requirements for your Web Help Desk deployment size.

Deployments with fewer than 20 techs

If your deployment will support 20 tech sessions or fewer, you can run Web Help Desk 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 your deployment will support more than 20 tech sessions, SolarWinds recommends installing Web Help Desk 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

Configuring the JVM

To increase the max heap memory on a JVM, edit the MAXIMUM_MEMORY option in the WebHelpDesk/conf/whd.conf file.

For other operating systems, install your own JVM and then update the JAVA_HOME option in the WebHelpDesk/conf/whd.conf file to point to your Java installation.

SolarWinds product integration requirements

The following table lists the SolarWinds products that integrate with Web Help Desk.

Supported Product Version
SolarWinds Orion platform Version 2017.1 and later
SolarWinds Network Performance Monitor (NPM) NPM 12.1
SolarWinds Server and Application Monitor (SAM) SAM 6.4.2
SolarWinds Network Configuration Monitor (NCM) NCM 7.5
DameWare Mini Remote Control (MRC) DameWare MRC 12.0.3

Database requirements

Web Help Desk uses an embedded PostgreSQL database as its standard database. The following table lists the supported databases.

Database Supported versions

PostgreSQL 9.2

PostgreSQL 9.3.2

PostgreSQL 9.4

PostgreSQL 9.6


MySQL 5.6

MySQL 5.7

Microsoft SQL Server

SQL Server 2008 R2 SP3

SQL Server 2012 SP1

SQL Server 2014

SQL Server 2016

For optimal external database performance, run Web Help Desk and a supported external database on separate servers.

Database hardware requirements

The following table lists the minimum software and hardware requirements for a server hosting MySQL and SQL Server.

Product Requirements
CPU speed 64-bit Dual Core 3.0GHz or better
Hard drive space 20 GB
Memory 3 GB plus 1 GB for every additional 10 techs

Oracle Java Database Connectivity (JDBC) driver requirements

Web Help Desk for macOS includes an embedded Java Virtual Machine (JVM). If you are running an external Oracle JVM, Web Help Desk 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 Web Help Desk 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 the Oracle website to download the latest JDBC driver.
