You may need to start DTP services after a new installation, migration, or upgrade. In this section:

Starting DTP Services on Windows

You can easily use the Windows Start menu to start and stop DTP services:

Click Start and right-click Parasoft> DTP> Start DTP Server.
Choose Run as administrator from the contextual menu. If your DTP distribution includes an embedded database server, the menu will also include an option for starting and stopping the database server.
Press any key to proceed when prompted.
Repeat the process to start Data Collector, the Parasoft Database service if your DTP distribution includes an embedded database server, and DTP Enterprise Pack if applicable.

You can also use Windows Services to start and stop DTP services, as well as change startup from automatic to manual.

See the documentation for your version of Windows for details.

Starting DTP Services on Linux

There are a few ways you can start DTP and its related services:

Use the dtpconsole.sh script
Use the automation scripts
Use the systemd services

Using the Console Script

In addition to starting and stopping DTP and its related services, the dtpconsole.sh script provides interactive management capabilities, such as configuring database connections.

Using the Automation Scripts

After the initial startup and configuration, you can start DTP applications using the dedicated scripts. The scripts are non-interactive and suitable for starting and stopping DTP services in automated environments. Please note that automation scripts are not compatible with crontab functionality. If you are using crontab functionality, use the dtpconsole.sh script to start and stop DTP.

DTP Server

Use the dtp.sh script located in the <DTP_INSTALL>/bin directory. You can specify the following commands:

`dtp.sh run`	Run the DTP server process in the current window.
`dtp.sh start`	Start DTP server as a background process.
`dtp.sh stop`	Stop DTP server.
`dtp.sh status`	Display the current status of DTP server.
`dtp.sh help`	Print the help to the console.

Data Collector

Use the datacollector.sh script located in the <DTP_INSTALL>/bin directory. You can specify the following commands:

`datacollector.sh run`	Run the Data Collector process in the current window.
`datacollector.sh start`	Start Data Collector as a background process.
`datacollector.sh stop`	Stop Data Collector.
`datacollector.sh status`	Display the current status of Data Collector.
`datacollector.sh help`	Print the help to the console.

DTP Enterprise Pack

Use the dtpservices.sh script located in the <DTP_INSTALL>/dtpservices directory. You can specify the following commands:

`dtpservices.sh run`	Run the Enterprise Pack process in the current window.
`dtpservices.sh start`	Start Enterprise Pack as a background process.
`dtpservices.sh stop`	Stop Enterprise Pack.
`dtpservices.sh status`	Display the current status of Enterprise Pack.
`dtpservices.sh reset-server`	Reset the DTP server connection settings for Enterprise Pack to the defaults. See Server Settings for information about the server configuration.
`dtpservices.sh help`	Print the help to the console.

In some unexpected instances, you may see the following message when running the stop on Linux:

"Time out on DTP Enterprise Pack process termination. Please kill all processes manually. (Refer to the documentation)"

This message only triggers if any of the children processes of the main DTP Enterprise Pack application (typically one of the service processes) started but was not killed completely. These processes must be terminated before starting DTP Enterprise Pack again.

Run following command:
pgrep node or pgrep -f <installation home>/nodejs/bin/node
This command will print out all processes that DTP Enterprise Pack started.
Run the kill command using the same argument to kill these process:
pkill node
or
pkill -f <installation home>/nodejs/bin/node

Using systemd Services

As alternative to using the dtpconsole.sh script, the automation scripts, or crontab to manage DTP, it is possible to configure custom systemd services on Linux systems that support systemd. Before doing this, ensure that the DTP services are not running. Please note that these systemd services are not compatible with crontab functionality. If you are using crontab functionality, use the dtpconsole.sh script to start and stop DTP.

To use systemd services:

Create a file for each DTP service where each file is in the format <servicefilename>.service.
- These files can be named whatever you want, but the filename must use the ".service" extension in order for systemd to process them correctly.
Place these files in the /etc/systemd/system directory.

Below are some sample systemd services for each of the DTP services that can be used in the files you created in the above steps. It is important to ensure that the User and Group for each service is consistent with the DTP installation owner. Additionally, the "ExecStart" and "ExecStop" options should correspond to your DTP installation location.

For DTP Server:

[Unit]

After=network.target

# When the database is MySQL and on the local machine...
# Wants=mysql.service

[Service]
# User/Group should be consistent with DTP installation owner
User=devtest
Group=devtest

Type=simple

ExecStop=/home/devtest/parasoft/dtp/bin/dtp.sh stop
# Set maximum file descriptor limit to max
LimitNOFILE=65536
SuccessExitStatus=143 SIGKILL
Restart=on-failure

[Install]

For DTP Data Collector:

[Unit]

For DTP Enterprise Pack (if installed):

[Unit]
Description=Parasoft DTP Enterprise Pack Service
# Wait for the network services to be started first

After the services have been configured, you can enable them to start automatically when the machine is restarted. For each service file you created, run the following:

sudo systemctl enable <servicefilename>

Once you have enabled all the services, reload the systemd manager configuration:

sudo systemctl daemon-reload

Then for each service you created, run the following to start them:

sudo systemctl start <servicefilename>

To check the status for a service:

sudo systemctl status <servicefilename>

To stop a service:

sudo systemctl stop <servicefilename>
