UNIX Monitoring Tool for PostgreSQL

by Gregory Smith | October 2010 | Open Source

Performance of your database server is directly tied to how well the underlying operating system is working, and there the performance is driven by the hardware you're using. To fit all of these pieces together—hardware performance, operating system performance, and database performance—you need a good monitoring system.

The simple performance tools on a UNIX-derived system are straightforward to use, and it's easy to show examples of good and bad behavior, the best way to teach how those tools are useful for monitoring. In this article by Gregory Smith, author of PostgreSQL 9.0 High Performance, we will cover iostat; Unix's monitoring tool.

Updating Software in Koha

by Amit Gupta Savitra Sirohi | November 2010 | Open Source

The Koha software is always changing, almost every day. These changes contain bug fixes, minor revisions to existing features, and entirely new features. You should keep the software updated to benefit from these changes.

Even if the new versions do not contain changes of interest to you, it is good practice to keep the software updated. If your version falls too far behind the current version, the update process to the latest version is likely to be very difficult.

In this article, by Amit Gupta & Savitra Sirohi, authors of Koha 3 Library Management System, we will learn how to download and install software updates. We cover the article in two steps—an orientation followed by a demonstration of the process.

Upgrading from Samba Server Version 3

by Marcelo Leal | April 2014 | Networking & Telephony Open Source

In this article by Marcelo Leal, author of Implementing Samba 4, the reader will learn some of the biggest differences between the Samba software Versions 3 and 4, and based on that, will understand the impact and the relevant considerations before planning a successful upgrade. The main aspects of such differences will be focused on the different working models and the new features and benefits that the upgrade can leverage.

We will learn about a step-by-step procedure to execute the upgrade and all the commands and scripts needed to go from Samba 3 to Samba 4's fully functional Domain Controller network services.

We will describe a guideline that can be well suited and requires just a few changes for small and medium installations, but bigger and more complex environments will need adjustments and customizations. The variety of configurations in production of the Samba Server Version 3 use cases are huge, and we will not be able to handle all the variations that our readers have implemented in their respective environments, but all the procedures and use case examples presented here should work as a rich base.

Upgrading OpenCart

by Murat Yilmaz | August 2010 | Beginner's Guides Open Source

It is wise to update our OpenCart environment to the latest version regularly. It protects our system against security vulnerabilities and allows us to use new features. It is also possible that the new OpenCart version will have several bug fixes.

Moreover, new versions can have new bugs. Because of this, it is a common practice to wait while a version with major changes matures and gets rid of serious bugs with minor release fixes.

In this article by Murat Yilmaz, author of OpenCart 1.4 Beginner's Guide, we shall learn about:

  • Making a backup of current OpenCart system
  • Downloading the latest OpenCart version

Use of Stylesheets for Report Designing using BIRT

by John Ward | July 2010 | Java Open Source

BIRT is an open source business intelligence and reporting tool built on top of the Eclipse Framework. BIRT is used by developers for building reports that can best represent data and tell a story of that data that is easy to follow. In addition, BIRT can be integrated into a product to allow that product to provide reporting capabilities. 

In this article by John Ward,author of BIRT 2.6 Data Analysis and Reporting we will look at how BIRT uses stylesheets in report designs and how styles can be grouped in a library to create themes. This will allow us to have certain sets of styles ready for use any time we develop a report so that we, as a report developer, can focus strictly on the technical aspects of the report while maintaining a consistent visual presentation.

by John Ward | July 2010 | Open Source

BIRT is an open source business intelligence and reporting tool, built on top of the Eclipse Framework. BIRT is used by developers for building reports that can best represent data and tell a story of that data that is easy to follow. In addition, BIRT can be integrated into a product, to allow that product to provide reporting capabilities.

In this article by John Ward,author of BIRT 2.6 Data Analysis and Reporting we will look at templates. Templates are existing report layouts that can be used as a starting point for new reports. This is useful if we use a similar layout in all our reports; we can then create a template and build from that for each new report.

User Access Control in Drupal 6

by David Mercer | April 2008 | Content Management Drupal Open Source

In this article by David Mercer, we will look at an entirely different aspect of running a Drupal website. Once we have added the functionality to the site, we now have to give some thoughts about how this functionality is to be accessed, or by whom. As the site grows, you will most likely feel the need to delegate certain responsibilities to various people. Alternatively, you might organize a team of people to work on specific aspects of the site. Whatever is required, at some stage you will have to make decisions about who can do what, and Drupal makes sure that it is possible to do precisely this.

Having Drupal simplify the implementation of your access control policies does not mean that the task is a trivial one. There is still much thought that needs to go on behind the scenes in order to create a sophisticated, and above all, effective policy for controlling access to the site. Because of this, we will spend a bit of time exploring the ramifications of the various choices available, instead of simply listing them. Taking a holistic approach to implementing an access control policy will ensure you don't end up with any nasty surprises down the line.

Specifically, this article will look at Planning an access policy, Roles, Users, and Access rules.
