VT-NET
VT-NET is a mission-critical system on which other high-performance applications are built, such as the Core Server, Auth Server and Notif Server. It involves a series of processes that run under the Linux OS, providing networking functions and transferring a high volume of data. It manages lines, stations and application processes to process all requests that enter the system.
Note
To read about lines and stations, visit the Glossary or hover over the terms in this article.
VT-NET is responsible for the following:
Managing communications, application processes and queues;
controlling lines and stations;
addressing inter-process messages;
managing memory and interfaces with the operating system;
executing, monitoring and auditing routines; and
generating and managing event messages.
Pre-requisites
To initialize VT-NET, you need to install all the necessary middleware components, such as the different servers, databases, and certificates. If you need assistance setting your environment, contact an admin.
Initialize VT-NET
To initialize VT-NET, go to your Linux terminal and access the corresponding environment with your username.
Warning
By default, VT-NET is installed with the VT724 user under the /veritran/vt-net/ directory, so all commands should be executed under that same user. Running commands with another user may result in permission or privacy issues.
To initialize VT-NET, run the following command:
/veritran/vt-net/bin/kernel -f /veritran/vt-net/networkDirectory/[ENVIRONMENT]_ NDA1.ini -d
Read Commands for more information about the different commands you can execute in the terminal, and read Logs to learn how to access and manage log files.
Processes in VT-NET
VT-NET is made up of a series of processes that can be categorized into two types: system processes and application processes. See the sections below to learn more about processes of each type.
System processes are the ones that need to be operating to guarantee that VT-NET runs correctly. These processes are:
Kernel
CMD Server
Sec Server
When retrieving the platform's processes through VT-NET commands, the results appear on a table. System processes can be identified on the table as CORE in the group column, as shown in the image below.
Important
Only one of each system process must be running within a node at the same time.
Application processes are the ones that perform certain functions that can implement business features, such as authorizing transactions or communicating with devices and external systems. These processes are:
Device Handler (DH)
Authorizator
Host Interface
Settlement
Notification Server (this process is optional and may not be present for every client)
App Builder
When retrieving the platform's processes through VT-NET commands, the results appear on a table. Application processes can be identified on the table with a product code, as shown in the image below.
Read Commands for information about the different commands you can execute in the terminal that will affect processes within VT-NET.
