The Oracle Call Interface (OCI) is the C API to the database, exposing the lowest-level, highest functionality of Oracle Database to the external world. This flexible API enables developers to create high-powered, very efficient n-tier applications to control resources used on both the client and server sides. Besides writing homegrown OCI applications, some of8

Oracles customers employ OCI indirectly by using OCCI, JDBC, and ODBC drivers, implemented on top of OCI. All of these applications share key features, including scalable connection/session management, SQL relational database access, runtime binding of input/ output data, implicit and explicit data conversions, server-side embedded script execution, data caching, globalization and multibyte support, and object access. Apart from providing a public interface, OCI is used internally by the Oracle server for distributed database access and data access within the server. OCI defines the internal communication protocol for client/ server and server/server communication. Open Source APIs. Oracle is committed to providing efficient data-access drivers to all developers, including those in the open source community. We work with the PHP, Perl, and Python developer communities to create the highest-quality access to Oracle Database. OCCI. Oracle C++ Call Interface provides a fully object-oriented method of accessing the Oracle Database. As a platform-independent, easy-to-use interface, OCCI provides seamless mechanisms to map Oracle objects to C++ objects. Precompilers. Precompilers provide simple and efficient data-access mechanisms for embedding SQL statements in applications written in various programming languages, such as C/C++, Java, Cobol, and Fortran. Oracle precompilers are ANSI compliant with Oracle-specific extensions. ODBC.

We are responsible for developing core technologies that underlie Oracles high-availability solutions such as clusters and standby databases. High availability is an area where Oracle excels; we are constantly looking to extend our lead by pushing the boundaries of the possible. Our goal is to either prevent failures or ensure that we can recover from all causes of failurebe they system failures, data failures, human error, or disasters. Some projects that we work on include self-healing systems, subsecond recovery of a database after a system crash, flashback technologies that can rapidly repair a damaged database, whether 2 gigabytes or 2 petabytes in size, and parallel recovery that harnesses the combined power of clusters of computers to cooperatively maintain database replicas for disaster recovery. The software that we develop must meet extremely demanding requirements. First, our code has to be reliable; software must work even when the system is failing. In addition, the software must perform well during recovery situations and impose minimal overhead during normal operation. For example, our designs must scale on multiprocessors containing hundreds of CPUs as well as clusters of many computers. Finally, our software must be easy to use. To meet such needs, we are building intelligent fault-detection and self-repair capabilities that can detect failure and automatically figure out the optimal repair option. If you are interested in the challenges inherent in building lifeline softwarecode that can function even when the rest of the system has failed or is failingplease talk to us.11

Database Resource Manager Group

Projects at Oracle

Todays databases typically run a variety of workloads, such as OLTP transactions, ad hoc queries, and long-running complex reports. In addition, they often host multiple applications as DBAs seek to fully exploit their server and storage systems. This reality makes workload prioritization and resource partitioning an important issue for any database. The Database Resource Manager provides DBAs with the ability to manage how multiple workloads use server and storage resources by specifying workload priorities, resource allocations, and utilization limits. Today, Resource Manager manages how multiple workloads use the databases CPUs by scheduling database processes, much like an operating system scheduler. It also manages their use of the disks for Oracle Exadata storage through a sophisticated I/O scheduler. For future releases, we need to control resources such as memory, internal caches, I/O for non-Exadata storage, parallel statements, and more. These implementations require devising sophisticated, innovative algorithms that are portable across different operating systems and different server and storage platforms. They require intimate knowledge of todays server and storage technologies, operating systems internals, and OS workload managers. Their implementations should have minimal overhead and should include optimizations for specialized environments like clustered databases, virtual machines, and NUMA systems. They will require product development on both Oracle Database and Oracle Exadata. We hire developers who can convert ideas to solutions and make Resource Manager a go-to product for all QoS and resource management needs. Developers also benchmark workload scenarios, publish best practice papers for customer use, and interact with hardware and software vendors to address platform or vendor-specific challenges and roadmaps. We seek strong analytical and problem-solving skills, operating system and storage system fundamentals, performance evaluation and tuning skills, and proficiency in C or C++. If you like solving complex problems and learning about new technologies, talk to us!Database Security

Data security is absolutely fundamental for todays connected world. Enterprises deploy sophisticated tools, identity management systems, scanning software, all with just one goal to protect data. The stakes are highcustomers are worried about the confidentiality of sensitive data; privacy of the employee, customer, or citizen data; and whether the next attack is going to come from well-heeled external hackers or informed insiders. We develop database security technology that provides defense in-depth for sensitive business data. We were the first in the industry to come up with innovative technologies such as protection realms, multifactor authorization, transparent data encryption, virtual private database, real-time audit warehouse, fine-grained auditing, multilevel database security, and data classification, to name a few. We pride ourselves in building security technology that is transparent to the applications, adds negligible overhead, and integrates with customers existing infrastructure. We are working in many exciting areas of database firewalls, embedded database access controls, database auditing, intrusion detection, compliance controls, key management, data privacy, secure configuration, data masking, and more. We work with many other groups and technologies, including applications, application servers, identity management, and operating systems. Our group is the perfect home for someone passionate about building security solutions that scale, perform, and, most importantly, stay many steps ahead of hackers and malicious insiders. You would shape how the majority of the enterprise customers would secure their data and enable a fully connected secure world.12

Database Server Manageability

After decades of industrial development, most database systems have become feature-rich but cumbersome to configure, tune, and test. This concern resonates with our customers and well-respected database community alike. Our groups vision is to develop a self-tuning, self-diagnosing database, designing technologies in the database kernel so that the database can manage itself out of the box. Consider that we are a small group of highly motivated, bright database system engineers; we have filed around 40 patents for self-managing technologies released in Oracle Database; we regularly publish papers in well-respected database conferences; and we boast an unusually high number of fun outings since the group formed several years ago. Our projects touch all corners of the database kernel, from query optimization and transaction processing, CPU, memory, and I/O resource management to backup and recovery mechanisms. We build self-tuning and advisory technologies to integrate all these separate components together in order to provide complete solutions to our customers. We have developed technologies in Oracle Database to automatically speed up execution time of a SQL and to self-diagnose performance bottlenecks in slow-running systems (even high-powered clustered database environments), all in a fraction of the time it takes to do so manually. We are currently expanding these offerings to cover exciting new problems such as cross-tier performance diagnostics, automated self-tuning for emergency situations, and building data interfaces for innovative UIs to empower DBAs to navigate the wealth of performance data captured in the database. Our group tackles such challenging problems, constantly exploring fresh ideas and always focused on providing a complete solution to help customers unleash the full potential of Oracle Database. We take charge, work with seasoned architects, and are part of the entire development process, from investigation to design, coding, and release. We seek intelligent, motivated engineers to help build world-class solutions, having fun as part of a team!Database Test and Productivity Tools Development

We are using the most advanced technologies, including grid architecture, flash storage, InfiniBand networking, and most importantly, smart scale-out storage. We are doing something simple14

to conceive but actually quite challenging and interesting to execute. For time immemorial, the disk farm has been populated with simple creatures: I seek, I read, I write, I write, I read, I seek... DEE-Dee-dee... Our basic idea is to make the disk farm intelligent. We want to populate the disk farm or grid with intelligent appliances that are inexpensive, maintain data redundancy for each other dynamically, spread workload amongst each other without the intervention of administratorseven as appliances, or drives within, are added or removed from the grid. Its designed for exabytes. Most importantly, we are making these appliances application-aware, and in their first incarnation, we are offloading a lot of heavyduty grunt work from our most important application, the database engine, and giving it to these now-smarter storage appliances to do so much more efficiently with the disk drives plugged into them. There are an ever-growing number of cooperative processing optimizations between our world-leading database server and our new storage appliance that we want to implement, and you can help us. Once you get the concept, the possibilities are limitless for innovation. We work cooperatively and frequently with our collegial hardware engineers, enriching our experiences.

With the breadth of technologies, you will have the opportunity to let your innovative spirit take flight, see new technologies that deliver business efficiencies, and contribute directly towards Oracles continued market leadership.Replay Technologies and Workload Intelligence

Technological progress is rapid and inevitable. Hence, change in modern IT environments is the only constant. Companies must stay up-to-date to maintain competitive systems as technology progresses. However, the reality is that adoption of new technology can be cumbersome and risky. Not many effective tools can reassure companies that new technology adoption will not negatively impact day-to-day business operations. The Oracle RDBMS is the only RDBMS that provides effective tools to help with new technology adoption. Our mission is to provide tools to allow IT infrastructure operators to answer the following questions with high confidence: Will my system continue to function properly after I apply change X? How much better performance can I expect if I adopt feature Y? To accomplish our mission, we have developed technology that allows the recording of production workload containing the full content of real user interaction with a companys IT infrastructure. Using the production workload, our features in Oracle Database allow the replay of the user workload on a system that represents the new technologically more advanced system. Repeated replay sessions can identify and remedy problems. Starting from Oracle 11g, features such as Database Replay and SQL Performance Analyzer give Oracle customers a competitive edge in new technology adoption and a glimpse of the exciting future work in the replay technologies area. Using SPA, the user can proactively assess the impact on individual SQL of any change in the RDBMS infrastructure. Using Database Replay, the full force of a production workload can be unleashed on a staging system that uses new technologies that need to be proven reliable before deployment in production. Replay technologies closely collaborate with Database Manageability to fine-tune operation of autonomic technologies using real workloads. Our group filed at least 10 patents for the technologies released in Oracle Database 11g; we regularly publish papers in well-respected database conferences (SIGMOD, VLDB); and we have many fun outings (annual ski trip, rafting, go-karting, and more). We are constantly exploring groundbreaking ideas. Many problems still are unsolved; a lot of research is still ahead. In our group, you get to take charge and be involved in the entire development process, from research to design, coding, and release. We seek intelligent, highly motivated engineers to help build unique technological solutions and have fun doing so as a team.Secure Enterprise Search

Google may be known for delivering search technologies to the individual user, but Oracle excels in enterprise search. One of our biggest announcements in many, many years.Larry Ellison, Oracle Chief Executive Officer, introducing Oracle Secure Enterprise Search at OpenWorld Tokyo 2006 Would you like to join a team of search experts and change the way everyone in the world finds information inside their enterprise? Enterprise search is a nascent field which is growing rapidly, and Oracle is poised to take advantage of the strengths of our enterprise20

platform and our Information Retrieval (IR) platform to present a simple, yet powerful search paradigm to the enterprise. We seek software developers to develop the next-generation architecture for search. Enterprise search has challenges beyond standard Web searchunique issues with accessing all the content, auditing, deployment, and administration in the enterprise. For example, page citations are typically less reliable for enterprise search, as Web page cross-referencing is not as prevalent in the intranet, and therefore alternate techniques must be applied. We quantify precision, recall, and hit rank based on both objective and subjective measures of relevance. Based on these quantifications, we identify and implement algorithms and heuristics that improve search quality for enterprise search. We also work on a wide range of relevancy improvement techniques such as social search and personalization based on your role within the enterprise. We constantly publish papers and develop intellectual property in the field. One unique challenge in the enterprise is security. Secure search capabilities place Oracle Secure Enterprise Search ahead of the competition. Tough to solve: how to deliver highly relevant results quickly in a secure fashion, honoring access privileges of information sources, and using user identities and roles to further improve search quality. Our applications are developed using SOA, making use of Web Services and associated Web technologies. From an application perspective, we focus on high performance through distributed computing techniques. We also use emerging technologies such as Ajax to devise unique visualization techniques for bringing a highly intuitive and useful enterprise search experience to our customers. In addition to developing the search application, we work closely with other Oracle IT to deploy search solutions throughout the Oracle intranet, tapping into real-world experiences to improve our product offering. For more information about Oracle Secure Enterprise Search, visit us here: oracle.com/us/products/database/secure-enterprise-search/index.html ...Semantic Web Database Technologies New England Development CenterProjects at Oracle

Semantic Web database technologies make data smarter, allowing machine-driven understanding of the relationships between data and discovery of new relationships. The W3C has introduced languages to standardize the representation, vocabulary, inferencing, and querying of relationships in the data. Semantic technologies are evolving quickly and moving from the domain of early adopters to general use in a variety of industries. Oracle Database provides native semantic data-management capabilities to do the following: Store rich relationships with data that go beyond traditional rows, columns, table joins, and Boolean relationships. This allows users to better model and discover complex real-world relationships in the data to obtain more semantically complete information for decisionmaking. It is accomplished using the W3C standard RDF graph data model and the rich relationship semantics of the RDFS/OWL languages, integrated and optimized on the Oracle object-relational model for scalability, reliability, security, and performance. Natively inference among the predefined relationships in the data to discover new relationships, guided by ontologies of related terms and concepts, and use RDFS/OWL and user-defined rules. This new inferred data is persisted in the database for faster querying. Query based on patterns of relationships, using the W3C SPARQL query language with partner and open source tools or relational SQL queries containing SPARQL-like queries.21

Projects at Oracle

Work is ongoing with C, Java, XML, SOA, database and application server technologies, and W3C standards to address the needs of a broad range of industries, including government, defense and intelligence, life sciences, clinical medicine and research, banking, publishing, and telecommunications. Oracle works with leading third-party semantic technology tools, applications and services providers, open source technologies, and active participation in the W3C standards body to meet our customers business-critical application needs. We seek developers familiar with W3C graph data languages, including RDF, OWL and SPARQL; reasoning, including first-order logic and description logic; network analytics, visualization, and management of graph data; and domain ontologies, taxonomies, and vocabularies.Server Technologies Performance

Performance is critical to all customers; our group helps make Oracle the worlds fastest database. We are responsible for improving, measuring, and analyzing the performance of Oracle Database. We focus on database algorithms but also investigate operating system, compiler, and hardware issues that affect database performance. We look at all kinds of workloads, including transaction processing, decision support, data mining, OLAP, ERP and CRM applications, Java, and customer workloads. Our projects range from low-level, path-length optimizations to high-level algorithm changes that allow Oracle to scale well on the largest systems. We also produce performance-related white papers and demonstrate record-setting benchmark results. Are you interested in getting the best out of the latest hardware architecturesSMP, MPP, NUMA, or clustersusing the most sophisticated database technology? Do you want to work with the latest and greatest hardware under development? If so, this is the place to be.Storage Engine (Space Management, Data Storage, Transaction Processing)

We design and develop the storage engine for Oracle Database. Work in this area is a confluence of systems (particularly file systems and clustered-server systems), algorithms, and database technology. We provide the unique opportunity to develop new algorithms and then apply them in the worlds most successful server product. You can solve extremely complex, challenging problems that draw on every aspect of your computer science background. This is hard stuff, and we do it better than anyone else in the world. If you are excited by the challenge posed by difficult problems and the creative satisfaction from being an innovator, consider us. Within the Storage Engine group, we have three core teams: Space Management Team. People want to store everything on disksbooks, pictures, health records, music, videos, everything. Disks are getting bigger. Disks are getting cheaper. But disks are not getting much faster or easier to manage. At the core of Oracles business is its ability to store data and do it in a high-performance, scalable, reliable, and manageable way. Now consider that we need to do this just as well for an exabyte of data. Disk space management is a fundamental component of the RDBMS that provides an abstraction to the database storage subsystem. Disk space requirements for the database are primarily of two kindstemporary scratch space required to store multimedia results generated in the database and persistent storage used to store user data. From managing the temporary space for sorting a terabyte of data to finding the best slot in the petabyte volume disk for storing the next piece of employee payroll information, intelligent disk space management is one of the foundations for high-performance OLTP and data warehouse systems. Disk space management needs vary for different kinds of data stored in the database. Storing a streaming video has different requirements than storing product item names. Developing22

an efficient storage management component that works for all data types and also scales for several hundred thousand concurrent users will be one of the toughest challenges we face. To explore these and many more challenges in the area of self-managing space management at Oracle, check us out. Data Storage Team. The data storage group is a core R&D group in Oracle RDBMS that designs storage and access structures for the entire database. The storage layer is responsible for the storage and retrieval of all data stored in Oraclerelational, XML, OLAP, warehouses, files, and more. We organize data inside disk blocks and create and manage efficient structures from which those blocks are accessed (for example, a B-tree, bitmap index, LOB, cluster, and more) and methods for accessing data from these transactional data structures. We have some intractable problems to solve in the area of distributed systems. SecureFiles is the worlds fastest and most feature-rich file system. It is a next-generation file system built in the databasedesigned with specialized algorithms for next generation Solid State Disks as well as next-generation, terabyte-sized memory and 1000 core multicore systems. Some of our recent efforts have been in areas related to compression, deduplication, encryption, sliding inserts for efficient XML storage, snapshots, file system caching and performance, and scalability in clustered server environments. We are also working on providing an intelligent storage subsystem for Exadata so that the database can push predicate evaluation, projection, and aggregation to the storage layer, effectively pushing the logic to the data as opposed to pulling massive amounts of data to the CPU. Our group has the charter of doing R&D of next-generation compression technology, both for file compression as well as DB compression, including advanced compression and Exadata hybrid columnar compression (EHCC). EHCC is a new column-major storage structure that caters to the business intelligence world for processing petabytes of information. Our group has been on the forefront of technology R&D. We seek people especially interested in joining a group where they can make a big difference. The work is exciting, challenging, and rewarding. This is a core area of the database providing tremendous opportunity to learn and contribute at the same time and giving you a platform to build a solid foundation for your career from which to launch. If you are interested in the challenge of algorithm design and the satisfaction of building a core engine that powers most of the worlds databases, consider our group. Transaction Processing Team. Our group is responsible for the core transaction processing engine within Oracle RDBMS. We provide support for the ACID properties of transactions, row-level and table-level locking, multiversion concurrency control (also known as consistentread), and transaction isolation levels. We also implement and support distributed transactions (two-phase commit logic) that help midtier application servers manage several resources like databases and message queues. Even though we work deep down in the Oracle kernel, we implement user-visible features like AS OF queries (flashback queries), flashback data archive (change history for tables), flashback transaction (unwinding committed transactions), and continuous queries (used in event processing). As a group closely allied with the data storage layer of Oracle, we are privy to on-disk block formats and work on implementing scalable locking solutions and increasing concurrency. Beyond our own immediate groups, we also contribute to groups like the recovery and buffer-cache groups (readable standby databases, cross-platform standby databases) and Exadata (processing blocks of tables on the storage servers). Some of our ongoing projects include lightweight capture of database change history, highly scalable

logging infrastructure, enhancements to undo space management, and a whole host of contributions to other groups within Oracle. Our work is part operating systems, part databases, part distributed and parallel systems. We are looking for candidates who are eager to contribute to one of the core development groups of the Oracle kernel. Our group is a great place to build a solid foundation in transaction management principles and work across both the database and middle tier.TimesTen In-Memory Database

Oracle TimesTen is the industry-leading in-memory database management system. It is intended for applications that must be instantly responsive, highly scalable, and highly available. Oracle TimesTen In-Memory Database supports all the basic functionality of a traditional database. However, TimesTen shakes all the assumptions of traditional diskbased databases by taking for granted the fact that memory is inexpensive and plentiful and thus relying on having all data in main memory. This assumption results in a simplified design, which in turn results in much higher performance than is possible for a traditional database system. Oracle TimesTen Database can be used in standalone mode as the only database used by applications. The database code can also be directly linked into the application for far greater performance than a traditional client/server configuration, as network roundtrips are eliminated. Such configurations are ideal for achieving real-time performance. As the need to handle events and analyze data in real time grows rapidly, so do exciting technical challenges in achieving the associated scalability, throughput, and fault-tolerance requirements. Oracle TimesTen can also be used in cache mode with Oracle Database, where it plays the role of a front-end cache to Oracle Database. This combination is also very exciting from a strategic perspective, as it provides a unique synergy of capabilities: fast in-memory access and real-time capabilities of Oracle TimesTen combined with the vast arena of advanced functionalities supported by Oracle Database. You can think of Oracle TimesTen as a high-performance turbocharger on top of the sophisticated Oracle database engine to greatly accelerate the end-user performance experience of an Oracle application. The TimesTen Team is a small, talented team. We seek creative engineers who like a challenging environment in which individuals can play leading roles in developing and defining technologies for any aspect of in-memory data management, including query processing, storage management, indexing, logging, recovery, replication, high availability, caching data, user interfaces, and performance evaluation. This is an opportunity to be a significant part of emerging technological trends and to help define the vision for future database technologies.

Projects at Oracle

Achieving high performance on a broad variety of platforms and exploiting new technologies are important to maintaining Oracles current and future leadership positions in the database market. The Virtual Operating System (VOS) group is an important part of Oracle Database Division, providing a portable, high-performance platform for Oracle Database. We build modules that provide process/thread management and scheduling, memory management, synchronization support, CPU and I/O resource management, intercluster and interprocess communication, high-performance file I/O, and more. We ensure Oracle Database is a market leader on all platforms, from clustered Linux blade servers to the largest NUMA servers. We define interfaces to the platform-specific layer that exploit OS-specific functionality, such as NUMA-aware memory allocation, dynamic reconfiguration, user-mode threads, and virtualization. Our evaluations of leading technologies such as InfiniBand as a high-throughput, low-latency interconnect and leading-edge microprocessors such as Niagara, Power, and IA-64 often lead to enhancements that result in record TPC benchmark results. We work with operating system and storage vendors to introduce new interfaces for Oracle Database. We collaborate with hardware/OS/storage vendors to understand their roadmaps and to propose improvements that lead to better database performance and functionality. Responsibilities for a developer in the VOS group include interfacing with other database developers to gather requirements for improving the database kernel, designing and developing kernel modules to introduce new functionality or improve performance, collaborating25
