This book is intended to help you continue on your exciting new path
towards obtaining the Oracle8i certified database administrator certification.
The book will give you the necessary knowledge of the Oracle Server architec-
ture and the hands-on skills you need to pass Exams 1Z0-024 and 1Z0-026.
Although the OCP exams for Database Administration can be taken in any
order, it is generally recommended that the Oracle8i OCP certification exam for
Performance and Tuning and the Oracle8i OCP certification exam for Network
Administration be the final exams taken in the series. ...
This document describes the tasks to install Oracle Database
10g Standard Edition on a Windows two-node cluster, using
Real Application Clusters (RAC) and Automated Storage
Management (ASM). This install also builds a general purpose
starter database with the Sample Schemas included and with
automatic disk backup enabled.
CIS provides benchmarks, scoring tools, software, data, information, suggestions, ideas, and other services and materials from the CIS
website or elsewhere (“Products”) as a public service to Internet users worldwide. Recommendations contained in the Products
(“Recommendations”) result from a consensus-building process that involves many security experts and are generally generic in
nature. The Recommendations are intended to provide helpful information to organizations attempting to evaluate or improve the
security of their networks, systems and devices.
Step by Step instructions to install Oracle Applications R12(12.1.1) on Oracle Enterprise Linux 5 are described in this article. This is a single node installation, meaning that the database, all product directories and AD core directories, and all servers (concurrent processing, forms, and Web) are installed on a single node under one common APPL_TOP.
The database node and the Applications node can be installed on the same machine. This type of installation is generally used for small systems or for demonstration purposes.
Oracle Primavera Contract Management, Business Intelligence Publisher Edition v14
A one-stop reference to concepts and usability of the core modules of a complex application Stephen D. Kell
Stephen D. Kelly graduated from Oregon State University in 1982 with a degree
in Construction Engineering Management. He got his start with a mid-sized general contractor who was willing to take a chance with this college graduate and they both saw the benefits of a computer system in the contracting world.
SQL is a high abstraction level language used exclusively as an interface to Relational Databases. Initially it lacked recursion, and, therefore, had a limited expression power, but eventually this construct has been added to the language. Here we'll explore how convenient SQL is for general-purpose programming.
Tuning of SQL code is generally cheaper than changing the data model. Physical and configuration tuning involves a search for bottlenecks that often points to SQL code or data model issues. Building an appropriate data model and writing properly performing SQL code can give 100%+ performance improvement. Physical and configuration tuning often gives at most a 25% performance increase.
Oracle Server Technologies and the Relational Paradigm
The relational paradigm is highly efficient in many respects for many types of data, but it is not appropriate for all applications. As a general rule, a relational analysis should be the first approach taken when modeling a system. Only if it proves inappropriate should one resort to nonrelational structures. Applications where the relational model has proven highly effective include virtually all Online Transaction Processing (OLTP) systems and Decision Support Systems (DSS).
ersonal “lives” were, generally not migrated into archives
because of their on-going nature although nearly all photos were treated as archival. The rationale was that
photos are fundamentally archives and this had to do with the mindset that Windows established by making
“My Pictures” a special folder, that would lead people to store all photos in one folder hierarchy. Most of
Bell’s photos are in a folder called “A Big Shoebox”. Over time, however, we also ended up storing photos
throughout the folder hierarchy because all items pertaining to a single subject, e.
Control of access to sensitive information is of concern to managers, information
officers, DBAs, and application developers, among many others. Selective access
control based on a user's level of security clearance can ensure confidentiality
without overbroad limitations. This level of access control enables confidence that
sensitive information will be unavailable to unauthorized persons even while
general users have access to needed information, sometimes in the same tables.
Planning and Organizing a Database
Planning for your database is the first step in organizing and implementing a database system. First define how the database will be used. This determines what type of database you need to create that will meet the needs of your business, for example, data warehousing, high online transaction processing, or general purpose. After you determine the purpose and type, you must outline the database architecture that will be used.
Automatic Locking Oracle locking is performed automatically and requires no user
action. Implicit locking occurs for SQL statements as necessary, depending on the
action requested. Oracle’s lock manager automatically locks table data at the row level.
By locking table data at the row level, contention for the same data is minimized.
Oracle’s lock manager maintains several different types of row locks, depending on
what type of operation established the lock. The two general types of locks are
exclusive locks and share locks.
The urban-rural meta-narrative seems likely to have a generally positive impact on these D-P
types, as they are net gainers in terms of population and economic activity, due both to
counter-urbanisation and in-migration from remoter regions. The Globalisation meta narrative
(here interpreted mainly in terms of economic restructuring effects) is also likely to have
predominantly positive impacts upon these types of non-urban region.
Another significant driver—in a world now more environmentall
conscious than ever—is a global thrust to develop projects whic
not only minimize GHG emissions but also help to displace GHG
emissions from other industrial sources. Thus, one of the more
significant advantages of gas-turbine and engine-based
cogeneration is the potential for significant GHG reductions.
Further, it is the monetization of GHG reductions and other poss
financial incentives that are helping to encourage and facilitate
development of cogeneration applications.
After completing this lesson, you should be able to do the following:
Write SELECT statements to access data from more than one table using equality and nonequality joins
View data that generally does not meet a join condition by using outer joins
Join a table to itself by using a self join
Storing User Data
There are several methods of storing user data in an Oracle database:
Note: Partitioned tables, index-organized tables, and clustered tables are covered in other courses.
A regular table (generally referred to as a “table”) is the most commonly used form of storing user data. This is the default table and is the main focus of this lesson. A database administrator has very limited control over the distribution of rows in a table.
Obtaining comprehensive data and information on public debt is challenging. Data
availability is limited along the dimensions of time, country coverage, and debt
completeness. For example, data on external public debt for developing countries are
generally available from the GDF dataset. However, the GDF does not cover advanced
economies, and separates public and private components of external debt only for long-term
debt. Similarly, the IFS database starts in 1970, but data are available for just a handful of
countries in the early years.
In general, Oracle database security is outside the scope of this document. Like all other systems used in
creating your cloud deployment, you are expected to properly secure them per industry best practices. Please
refer to guides such as the Oracle Database Security Checklist, the Oracle Database Security Guide, and similar
resources and apply them as appropriate in your environment.
In general, Oracle VM HA enables the restart of an Oracle VM guest on either the
same physical machine or a different machine, if more than one physical machine is
available in the server pool. However, in any case, Oracle VM would operate on the
VM guest as a whole, restarting whatever is running within it.
The reason is that the Oracle VM guest is usually unaware of the applications
running in the virtualized environment as much as the application is typically
unaware of the Oracle VM guest it is running in.
