Transitioning to Locally-Managed Tablespaces :
Oracle 8.1.6 offered a new format for tablespace storage management –
locally-managed tablespaces – that offers significant improvements in
tablespace performance and free space management. Oracle 9i Release 2 improved
upon segment storage in locally-managed tablespaces with the Automatic Segment
Storage Management option. This article delves into the advantages of using locally-managed
tablespaces over dictionary-managed tablespaces and suggests practical methods
to achieve the transition. Oracle's Wrap Utility : With Oracle's wrap
utility, you can turn the inner workings of your code into an impenetrable
black box, for the most part, to protect your property. Learn how in this
article from Steve Callan. Striking Gold with LogMiner - Part 1: Getting Started :
Oracle's LogMiner utility has been around for several years now, and it
originally appeared as a new feature (as opposed to being an improvement of
something else). The purpose of this series is to help demystify some of the
procedures, illustrate some examples of using LogMiner, and to recommend cases
where LogMiner should be a DBA's primary tool for recovering lost data. Decrypting Oracle's DBMS_OBFUSCATION_TOOLKIT :
To secure sensitive data, Oracle provides developers with the
DBMS_OBFUSCATION_TOOLKIT, an industrial strength version of the DBMS_RANDOM
package. You may feel the need of a decoder just to keep track of all the acronyms
and to decrypt the errors in Oracle's sample code, but once you see how easy it
is to use, you'll be able to take Oracle's code example and modify it for your
own use. Generating random numbers and strings in Oracle :
Generating random numbers or strings is oft-times a necessity. Oracle provides
a random number generator that is faster than writing your won random
generation logic in PL/SQL, and can generate both character and alphanumeric
strings. Perhaps it is time to learn more about the DBMS_RANDOM package. Unwrapping Oracle's DBMS Packages: Understanding Oracle's
Random Number Generator : Beginning with later versions of
Oracle8, Oracle has provided a means of generating random numbers. This
built-in package, DBMS_RANDOM, is fairly simple to use, and can generate random
numbers which are generally good enough for the needs of most users. Learn more
as Steve Callan unwraps the first DBMS package of this series.Oracle Database Resource Manager, Part 3: Conclusion :

session utilization of DRM resources. Oracle Database Resource Manager, Part 1:Overview :
Oracle Database Resource Management (DRM) provides tools that allow any Oracle
DBA to manage a database server's CPU resources effectively for application
user groups and during different resource demand periods. This article provides
a brief overview of how DRM works and then delves into the preparations
necessary to implement a simple DRM configuration. Oracle Optimizer: Moving to and working with CBO - Part 7

Oh Danny Boy, The DBMS_PIPES Are Calling :
Oracle pipes have been around for a long time but just how many use this
powerful mechanism? James Koopmann explores this feature, reminding us all that
it is not dead yet. It All Depends on the CONTEXT: Using the SYS_CONTEXT Function
: The SYS_CONTEXT function is the recommended replacement method
for obtaining information about users and environment variables instead of the
deprecated USERENV function. This versatile function has been expanded in
Oracle 9i to provide a plethora of information about the Oracle database and
its processes as well as its users and sessions. Document Management with Oracle Text :
Powerful procedures for handling image, audio, video and the text data in
various formats are incorporated in the Oracle database kernel code. Marin Komadina
looks at the ins and outs of the feature originally known as ConText, then interMedia
Text, and finally Oracle Text. Altering Oracle's SQL*Plus Help Facility :
