Configuring and Managing the Mailbox Server Role

by Michael Van Horenbeeck Peter De Tender | September 2013 | Cookbooks Enterprise Articles Microsoft

In this article by Michael Van Horenbeeck and Peter De Tender, authors of the book Microsoft Exchange 2013 Cookbook, you will learn how to perform the tasks necessary to set up, configure, and maintain the Mailbox Server Role, including:

  • Creating and removing mailbox databases
  • Mounting and dismounting databases
  • Moving database files to another location
  • Configuring circular logging
  • Creating and removing mailboxes
  • Managing resource mailboxes
  • Configuring mailbox size limits
  • Managing personal archives
  • Assigning mailbox permissions
  • Moving mailboxes to another database
  • Managing Public Folders
  • Configuring send and receive connectors
  • Configuring Accepted domains
  • Configuring message size limits

Over the years, the Mailbox Server Role has evolved into something more than just a place where mail data is stored. Although its primary role remains storing and managing mail-related data, it inherited large chunks of what used to be the Hub Transport server and Unified Messaging server. This shows that the Mailbox Server role in Exchange 2013 resembles an Exchange 2010 multi-role server in many ways.

Reporting Based on SSRS

by Kamalakannan Elangovan | September 2013 | Cookbooks Enterprise Articles

In this article, by Kamalakannan Elangovan, the author of Microsoft Dynamics AX 2012 Reporting Cookbook, we will understand and acquire the skills necessary to be good at reporting based on SSRS.

This article will cover the following recipes:

  • Creating a matrix report
  • Creating a multicolumn matrix report
  • Creating a column chart
  • Creating a line chart

The legacy reporting system in Dynamics AX had very limited capabilities of how you can render data. Something as simple as adding an image and placing it right was a mammoth task, while things such as graphs and charts were not imaginable. SSRS takes away this pain and makes it easy to represent data in different formats. SSRS reports help create easier and convenient representation of data graphically that is easy for the end user to assimilate. This article will discuss recipes that cover the different kinds of controls other than the table layout discussed so far that can be used to represent data, such as matrix, charts, and gauges. The reader will be familiarized with the different controls and how they can be put to use in reports through this article.

Google Guice

by Hussain Pithawala | September 2013 | Open Source Web Development

In this article by Hussain Pithawala, author of the book Learning Google Guice we will develop a web application in Java using servlets and JSPs, and will see how Guice makes it simple to wire dependencies and helps to achieve separation of concerns easily. It even provides a programmatic approach to confi gure routing to servlets and JSPs while avoiding declarative approach in web.xml. As part of our learning we will fit flight search functionality in a web application. It is assumed that the reader is familiar with JSP, servlet development, and knows how to deploy a WAR file to a web container. Use of Tomcat to deploy the examples is suggested. We also need an extension of Guice for web development, guice-servlet-3.0. As usual, the dependency for this has been declared in pom.xml and once packaged it would be available in WAR (web application archive) also.
