You should verify that all requirements have been met before you begin installing DTP, migrating from Concerto (4.x) to DTP, or upgrading to a new version of DTP.

In this section:

Operating System

64-bit versions are required for all platforms. DTP requires 64-bit Java Runtime Environment. 

Windows

The following versions are supported:

• Server 2016
• Server 2019
• Windows 10

Microsoft .NET Framework 4.0 is required.

Linux

You can install DTP on Linux distributions that support 64-bit Java Runtime Environments (e.g., Ubuntu 14.04, 14.10, or RHEL Server 6.x).

A dedicated non-root user account is recommended for installing and managing DTP on Linux. A non-root user account is required for installing and managing DTP distributions that include an embedded database server.

Database Requirements

DTP supports MySQL and Oracle databases. Refer to the Database Settings chapter for details about installing and setting up the database server for use with DTP.

MySQL

• MySQL 5.6.25 to 8.0.x

Oracle

The Oracle database should not be installed on the same machine as DTP. The following versions are supported:

• 19c
• 18c
• 12c 
• 11g

Hardware

If you are installing DTP on a virtual machine (VM), make sure to allocate enough resources. Running DTP on a physical machine may result in greater performance.

• Quad core processor (or higher) with 2GHz CPU
• 8 GB memory (10 GB recommended if using MySQL). By default, 4 GB are allocated to DTP Server and Data Collector.
• If you are installing MySQL with DTP, two hard drive partitions are required, as well as 100 GB for the database and 60GB for programs.
• For heavy usage (more than 100,000 tests per day), you should install the database on a dedicated database server (physical machine) to ensure optimal performance of I/O writes.
• DTP server cannot be installed on a machine with an underscore ("_") in its name.

An additional 4 GB of RAM is recommended if you are installing DTP Enterprise Pack.

Ports

Before you begin installation, you should verify that the necessary ports are available:

You can customize the DTP Server ports as necessary. See Reconfiguring DTP Ports.

DTP Enterprise Pack Ports

The following ports must be available if you are installing DTP Enterprise Pack: 

Browsers

The latest version of the following browsers are supported:

• Internet Explorer (compatibility view must be disabled)
• Microsoft Edge
• Firefox
• Google Chrome
• Safari

Open File Descriptor Limit

Linux imposes a limit on the number of open file descriptors per process, which affects the number of allowable concurrent open connections that DTP can safely support. If many concurrent users will interact with DTP components, such as Report Center Dashboard or REST APIs, you should increase the open file descriptor limit before starting DTP.

Parasoft recommends setting the limit to approximately 100 times the number of concurrent users logged in. For example, if you expect 100 concurrent users, an open file descriptor limit of 10,000 should be sufficient.

Server behavior is inconsistent across operating systems, so you should use discretion when determining the proper limit for your environment. Methods for increasing the limit vary widely for different distributions. Consult your operating system documentation to determine whether it is possible to increase the limit and how to do so.

ZIP Extractor

The installation machine must have a program installed that can unzip compressed folders and files. 

Microsoft Visual C++ Redistributable

The Microsoft Visual C++ Redistributable package (2015 or higher) is required for the DTP Enterprise Pack database on Windows. The package is very common and may already be installed on your system. If the package is not already installed, the DTP installer will attempt to download the package.
