System Administrator Toolkit: Process Management TipsLearn how to get the UNIX® process information you need. For all system administrators, it is one of the most basic requirements to understand the processes that are running on their UNIX systems. A standard list of processes is useful, but the information it provides is malformed or does not contain the required process or information. The ability to select specific types of data from a list of processes makes it easier to manage tasks. In th

reduce read from database and data sourcesThe open source memcached tool is a cache for storing commonly used information, and with it, you do not have to load (and process) information from slow resources, such as disks or databases. The tool can be deployed in a dedicated case or as a way to run out of excess memory in an existing environment. Although memcached is easy to use, it is sometimes misused or used in the wrong environment type. In this article, learn the best time to use memcached.

Not necessarily.Http://www.ibm.com/developerworks/cn/java/j-5things2.htmlJava object Serialization (serialization) is so basic in Java programming that it can easily be taken for granted. But, as with many aspects of the Java platform, serialization always pays off as long as you dig deeper.
