Deadlock Detection and Recovery in Linux Book Review:

A deadlock occurs when there is a cyclic dependency between two or more threads, or processes, for some set of resources within operating system environment. A set of processes is deadlocked if each process is waiting for an event that only another process in the set can cause. My thesis aims at creating a tool, which can be used by an application developer for detecting the occurrence of a deadlock. It also helps the developer in analyzing the cause of deadlock, since the project provides him with information, such as the deadlocked processes and the resources causing it. The developer can also view the log file, which is generated by this tool to study the sequence of events, such as locking or unlocking of the resources. The outline of the project is as follows: A wrapper function dd_semop has been developed around the system call semop. An application program has to include a header file "libdeadlock.h" in order to use this wrapper functionality. A daemon process has also been developed dl_mgmt, which carries out the major functionality for deadlock detection and recovery. The wrapper function communicates with the daemon process, which runs in the background and actually verifies whether a lock can be granted or not and communicates back the possibility of a deadlock. Once the tool provides the output and depending on the users feedback to it, the tool provides a mechanism to continue execution without deadlock. Thus, this research project provides a comprehensible tool to study and manage deadlocks in a Linux flavor known as Fedora. Deadlock is thus a potential problem. Timely detection of deadlock and its cause are essential for resolving the error and maintaining forward progress.

Pro Oracle Database 11g RAC on Linux Book Review:

Pro Oracle Database 11g RAC on Linux provides full-life-cycle guidance on implementing Oracle Real Application Clusters in a Linux environment. Real Application Clusters, commonly abbreviated as RAC, is Oracle’s industry-leading architecture for scalable and fault-tolerant databases. RAC allows you to scale up and down by simply adding and subtracting inexpensive Linux servers. Redundancy provided by those multiple, inexpensive servers is the basis for the failover and other fault-tolerance features that RAC provides. Written by authors well-known for their talent with RAC, Pro Oracle Database 11g RAC on Linux gives you a rock-solid and technically flawless foundation on which to build your RAC-management skills. Authors Julian Dyke and Steve Shaw share their hard-won experience in building RAC clusters, showing you how to build for success using the very latest Oracle technologies, such as Automatic Storage Management (ASM) and Oracle Clusterware. You’ll learn to troubleshoot performance and other problems. You’ll even learn how to correctly deploy RAC in a virtual-machine environment based upon Oracle VM, which is the only virtualization solution supported by Oracle Corporation. RAC is a complex and powerful technology. It demands expertise in its deployment. You can’t just “wing it” in creating a RAC solution. Julian and Steve have earned the right to term themselves expert—in Pro Oracle Database 11g RAC on Linux, they offer a rigorous and technically-correct treatment of RAC that helps you build a solid foundation of expertise and achieve success.

Operating Systems Book Review:

For a one-semester undergraduate course in operating systems for computer science, computer engineering, and electrical engineering majors. Winner of the 2009 Textbook Excellence Award from the Text and Academic Authors Association (TAA)! Operating Systems: Internals and Design Principles is a comprehensive and unified introduction to operating systems. By using several innovative tools, Stallings makes it possible to understand critical core concepts that can be fundamentally challenging. The new edition includes the implementation of web based animations to aid visual learners. At key points in the book, students are directed to view an animation and then are provided with assignments to alter the animation input and analyze the results. The concepts are then enhanced and supported by end-of-chapter case studies of UNIX, Linux and Windows Vista. These provide students with a solid understanding of the key mechanisms of modern operating systems and the types of design tradeoffs and decisions involved in OS design. Because they are embedded into the text as end of chapter material, students are able to apply them right at the point of discussion. This approach is equally useful as a basic reference and as an up-to-date survey of the state of the art.
