Popular
Oracle Install Guides for Solaris and Linux
Be sure to
check out the latest versions of our always-popular Oracle
installation guides. We’ve updated our step-by-step guides for
Oracle8i Release 3 (version 8.1.7) for both Solaris and Linux. These
guides help you install Oracle software and get a database up and
running quickly, while following best practices and leveraging
techniques for scalability and reliability.
Check out http://www.dbspecialists.com/4dbas/present.html
to download these and our many other white papers.
Keep
Yourself Up-to-Date on Known Oracle Security Weaknesses
From time to
time, Oracle users discover weaknesses in the security model of
Oracle products. These faults could allow a hacker or malicious
coworker to cause serious damage to your Oracle systems and your
business.
For example,
performing a “Typical” install of Oracle 8.1.5 on Solaris or
Linux could create a security hole that allows users at the
operating system level to gain root privileges on the server. A
separate security weakness in Enterprise Manager 2.0.4 and 2.1
leaves your SYSDBA password in a temporary file on the database
server after each backup job runs.
When Oracle
Corporation learns of new security exploits, they post bulletins on
their website and release emergency patches so that the exploit can
be eliminated as soon as possible. You can see a list of current
security alerts on the Oracle Technology Network website at http://technet.oracle.com/deploy/security/alerts.htm,
and you can download patches from Metalink at http://metalink.oracle.com.

Oracle Resources at Your Fingertips
In last

with you.
Tuning
Applications - Practical Knowledge for DBAs and Developers
Database
Specialists’ president, Roger Schrag, will present a technical
session on tuning applications at the International Oracle Users
Group - Americas’ Conference taking place from April 29 to May 3
in Orlando. Even if you’re not attending the conference, you can
read the white paper at http://www.dbspecialists.com/4dbas/present.html#explain_and_tkprof.
The paper
provides an overview of the EXPLAIN PLAN and TKPROF functions built
into the Oracle server and demonstrates how developers and DBAs use
these tools to get the best performance out of their applications.
It’s titled, “Use EXPLAIN PLAN and TKPROF to Tune Your
Applications” and provides many real-life examples so that
you’ll come away with as much practical knowledge as possible.
