otrs online teacher recruitment system,
OTRS, an initialism for Open-source Ticket Request System, is a free and open-source trouble ticket system software package that a company, organization, or other entity can use to assign tickets to incoming queries and track further communications about them It is a means of managing incoming inquiries, complaints, support requests, defect reports, and other communications

OTRS is part of the Lisog open source stack initiative

Every ticket generated by the system has persistence or "history" showing what happened to the ticket within its life cycle OTRS has the ability to merge multiple requests about the same incident, thus making it possible to work on an incident rather than on singular requests OTRS is a multiuser system which means that multiple agents may work simultaneously on the tickets in OTRS, reading the incoming messages, bringing them in order, and answering them OTRS is highly scalable, capable of handling thousands of tickets per day and a nearly unlimited number of simultaneously working agents

OTRS has integrated functionality for creating, reworking and searching FAQ texts The FAQ texts may be incorporated into the agents' answers on tickets

By using a multilingual web user interface, OTRS is usable independently from the respective operating systems since it is operated from a web browser Furthermore, this facilitates the usage of OTRS by external agents or even customers participating in, working on or contributing to tickets

OTRS establishes a framework of functions For example, the System for Incident Response in Operational Security SIRIOS of the Federal Office for Information Security, Germany, is based on OTRS

The Open-source Ticket Request System OTRS is more than a mailing list notification system for ticket requests

Since its beginnings OTRS has been implemented in the programming language Perl The web interface is made more user-friendly by using JavaScript which can be switched off for security reasons Different functionalities are implemented as reusable backend modules, making it possible to create custom modules to extend the functionality of the OTRS system

The web interface itself uses its own templating mechanism called DTL Dynamic Template Language to facilitate the display of the systems output data

Originally, OTRS worked only on MySQL databases Support has since been added for PostgreSQL, Oracle, DB2 and Microsoft SQL Server OTRS may be used on many UNIX or UNIX-like platforms eg Linux, Mac OS X, FreeBSD, etc as well as on Microsoft Windows

The scalability of OTRS systems may be increased by using mod perl for the Apache Webserver or by separating the database and web server systems, allowing a large number of simultaneously working agents and high volumes of tickets

In UNIX and UNIX-like environments OTRS works closely with system programs like the mail transfer agent Postfix or the mail filter procmail


OTRS has a plugin mechanism, and many programmers have written add-ons to bring in new functions In March 2011 a public repository named OPAR OTRS Package ARchive started; until August 2015 about 140 add-ons were published
