Availability requirements for database systems are more stringent than ever before with the widespread use of databases as the foundation for ebusiness. This paper highlights <i>Fast-Start</i>#8482; <i>Fault Recovery</i>, an important availability feature in Oracle, designed to expedite recovery from unplanned outages. Fast-Start allows the administrator to(More)
The Oracle Database In-Memory Option allows Oracle to function as the industry-first dual-format in-memory database. Row formats are ideal for OLTP workloads which typically use indexes to limit their data access to a small set of rows, while column formats are better suited for Analytic operations which typically examine a small number of columns from a(More)
Modern enterprise, web, and multimedia applications are generating unstructured content at unforeseen volumes in the form of documents, texts, and media files. Such content is generally associated with relational data such as user names, location tags, and timestamps. Storage of unstructured content in a relational database would guarantee the same(More)
State-of-the-art OLTP systems execute distributed transactions using XA-2PC protocol, a presumed-abort variant of the Two-Phase Commit (2PC) protocol. While the XA specification provides for the Read-Only and 1PC optimizations of 2PC, it does not deal with another important optimization, coined Nested 2PC. In this paper, we describe the Logging Last(More)
Loop fusion has been a traditional transformation in optimizing and parallelizing compilers. There are various benefits in performing loop fusion. Most trivially, loop fusion reduces the overheads associated in implementing loops in computer hardware by a factor of 2. But, in addition, loop fusion also holds promise in reducing the paging traffic in the(More)
