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
- 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
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
- 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
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.
Web Help Desk uses an embedded PostgreSQL database as its standard database. The following table lists the supported databases.
|Microsoft SQL Server||
SQL Server 2008 R2 SP3
SQL Server 2012 SP1
SQL Server 2014
SQL Server 2016
SQL Server 2017
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.
|CPU speed||64-bit Dual Core 3.0 GHz 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.
Discovery connector requirements

|Discovery connector||Supported versions|
