Mastering ServiceNow - Second Edition

Overview of this book

ServiceNow is a SaaS application that provides workflow form-based applications. It is an ideal platform for creating enterprise-level applications giving requesters and fulfillers improved visibility and access to a process. ServiceNow-based applications often replace email by providing a better way to get work done. The book steps through the main aspects of the ServiceNow platform, from the ground up. It starts by exploring the core architecture of ServiceNow, including building the right data structure. To add business logic and control data, and interactivity to user interaction, you will be shown how to code on both server and the client. You will then learn more about the power of tasks, events and notifications. The book will then focus on using web services and other mechanisms to integrate ServiceNow with other systems. Furthermore, you will learn how to secure applications and data, and understand how ServiceNow performs logging and error reporting. You will then be shown how to package your applications and changes, so they can be installed elsewhere and ways to maintain them easily. If you wish to create an alternative simple interface, then explore ways to make ServiceNow beautiful using Service Portal. By the end of the book, you will know the fundamentals of the ServiceNow platform, helping you be a better ServiceNow System Administrator or developer.

Preface

Running background scripts


The simplest place to experiment with server-side scripting is perhaps the Background Scripts section in ServiceNow. This provides you with a large text box in which you place your code and a button saying Run Script, without any fuss, formatting, or further complexity. Outputs from your session during execution (such as log statements) are captured and presented to the screen. This, therefore, provides an excellent place to run server-side code where you need to monitor the results, where you can experiment, or where you need to run one-off scripts.

Navigate to Background Scripts by going to System Definition > Scripts (Background).

You will be presented with a large script box; however, before you get too enthusiastic, heed the warning shown. The reason that accessing background scripts requires elevated privileges is to remind you that some badly written code can, in fact, delete all your data. Never experiment in a live production instance!
