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 64-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.
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 |
PostgreSQL 13.7 (External database only) PostgreSQL 13.9 PostgreSQL 14.2 (External database only) |
| MySQL |
MySQL 5.7 MySQL 8.0 |
| Microsoft SQL Server |
SQL Server 2014 SQL Server 2016 SQL Server 2017 SQL Server 2019 |
Database hardware requirements
The following table lists the minimum software and hardware requirements for a server hosting MySQL, SQL Server, and a supported PostgreSQL version.
For optimal external database performance, run WHD and a supported external database on separate servers.
| Product | Requirements |
|---|---|
| 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 |
External database options
WHD supports the following SQL Server and MySQL versions as external databases:
-
SQL Server 2014
-
SQL Server 2016
-
SQL Server 2019
-
MySQL 5.7
If you are running WHD 12.6 and later, you can also use the following PostgreSQL versions as external databases:
-
PostgreSQL 13.7
-
PostgreSQL 14.2
See Database datatypes for information about mapping information types across other databases types.
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.
