This guide provides end-to-end guidance for managing performance and scalability throughout your application life cycle to reduce risk and lower total cost of ownership. It provides a framework that organizes performance into a handful of prioritized categories where your choices heavily impact performance and scalability success. The logical units of the framework help integrate performance throughout your application life cycle. Information is segmented by roles, including architects, developers, testers, and administrators, to make it more relevant and actionable. This guide provides processes and actionable steps for modeling performance, measuring, testing, and tuning your applications. Expert guidance is also provided for improving the performance of managed code, ASP.NET, Enterprise Services, Web services, remoting, ADO.NET, XML, and SQL Server.

Red Hat Enterprise Linux ( RHEL) is a Linux distribution produced by Red Hat and targeted toward the commercial market, including mainframes. Red Hat commits to supporting each version of RHEL for 7 years after its release. All of Red Hat’s official support, all of Red Hat’s training and the Red Hat Certification Program center on the Red Hat Enterprise Linux platform.
New versions of RHEL are released every 18 to 24 months. When Red Hat releases a new version of RHEL, customers may upgrade to the new version at no additional charge as long as they are in possession of a current subscription (e.g. the subscription term has not yet lapsed).

qmail is the #2 mail server on the planet. It was written by Daniel J. Bernstein as a more secure replacement for the popular Sendmail program. Life with qmail is one of the definitive documents for installing, configuring and using qmail. It contains a wealth of easy to follow information in a single page document. Besides the online HTML version, there there are PDF, postscript and ASCII versions.

Link: http://www.lifewithqmail.org/
Life with qmail is aimed at everyone interested in running qmail, from the rank amateur (newbie) who just installed Linux on a spare PC all the way up to the experienced system administrator or mail administrator. If you find it lacking or unclear, please let me know. Send comments to lwq@sill.org.
There’s a wealth of information available on qmail from a variety of sources. Some is targeted to newbies, some assumes that the reader is more experienced. Life with qmail is an attempt to "glue" this information into a single source, filling in some of the cracks and assuming only that the reader has basic skills such as:
- Manipulating files/directories under UNIX
- Operating a web browser or FTP client
- Following directions
Also available from this link is Life with qmail-ldap
qmail-ldap is a patch to qmail 1.03 to retrieve all user data from a ldap-directory rather then from files on the disk. This allows easier administration, especially in distributed environments. There is also clustering support builtin making qmail-ldap very well suited for big mail installations at ISPs.

phpMyAdmin is the supreme database administration system for MySQL databases. It is also one of the oldest and most widely used open source applications under active development available today.
The official documentation covers everything all in one (very) long page: requirements, installation, setup, configuration, faq and glossary.
Link: http://www.phpmyadmin.net/documentation/
phpMyAdmin can manage a whole MySQL server (needs a super-user) as well as a single database. To accomplish the latter you'll need a properly set up MySQL user who can read/write only the desired database. It's up to you to look up the appropriate part in the MySQL manual.
