Are you secure? Securing the Oracle Network

Steven Karam's picture

Last month we talked about basic Oracle security, and set out principles for a top notch secure system. These included passwords, the principle of least privilege, and roles.

This month we journey into the fascinating world of Oracle Network Security. The topics covered will not involve the Oracle Advanced Security option: it's too big to cover here, and it is an added expense that many companies do not want. Instead, we will go over basic network security that can be implemented by anyone who uses Oracle. It is built in and so is already part of your system.

Managing XML using Oracle's XMLDB

This article introduces Oracle XML DB features to the DBAs and Developers who are not actively working with XML. It offers a quick start to those who finds quite a lot of Oracle XML literature around, and who is not sure where to begin.

Are You Secure? Get the most out of Oracle's security features

In the rapidly shifting world of database technology, one fact has always been, and will always remain, true: a great database is no good if it can easily be broken into. A faulty security plan is not just vulnerable to hackers; it opens your company to data theft, corruption, or even legal action.

Oracle Data Pump - Part III

James Koopmann's picture

On our quest to learn about Oracle's Data Pump utility it has often been compared to the old export and import (exp & imp) utilities that we have all grown to love (or hate). This article is where where Data Pump takes a detour from these old utilities and begins to shine. This article will explore some of the export modes available and give examples on how to export selected object types and dependencies those objects have.

Using srvctl to Manage your 10g RAC Database

Oracle recommends that RAC databases be managed with srvctl, an Oracle-supplied tool that was first introduced with 9i RAC. The 10g version of srvctl is slightly different from the 9i implementation. In this article, we will look at how -- and why -- to manage your 10g databases with srvctl.

Oracle Data Pump - Part II

Since we are all familiar with Oracle’s original export (exp) utility, and in my opinion Data Pump will be replacing exp soon, I thought it would be good to start off getting familiar with this utility by some relatively simple Data Pump exports (expdp) that are similar to the way we have used exp in the past. In particular the FULL export.

RAC Filesystem Options

DBAs wanting to create a 10g Real Applications Cluster face many configuration decisions. One of the more potentially confusing decisions involves the choice of filesystems. Gone are the days when DBAs simply had to choose between "raw" and "cooked". DBAs setting up a 10g RAC can still choose raw devices, but they also have several filesystem options, and these options vary considerably from platform to platform. Further, some storage options cannot be used for all the files in the RAC setup. This article gives an overview of the RAC storage options available.

Not using RMAN? You may be missing out on one of Oracle's best features!

When Oracle released RMAN (Recovery Manager) in Oracle 8 they changed the way databases can be backed up and recovered in the event of disaster. Unfortunately, Oracle shops have been slow to embrace RMAN often times because the change required a leap of faith into the new backup / recovery process as well changes to scripts, procedures, etc. This article will introduce the reader to RMAN and explain why every DBA should use it.

Oracle Data Pump - Part I

James Koopmann's picture

The last couple articles I have written focused on meta-data or DDL extraction for Oracle. The search for a part III to those articles lead me to Oracle's Data Pump utility. Not necessarily for the data movement piece but because it has an API for meta-data. Well even though I have been using 10g for quite some time, I have yet to use Data Pump. I thought this would be a great way to introduce myself, and possibly you the reader, to this new utility. This article will serve as a basic introduction to Data Pump and then in subsequent articles we will walk through the new command line options for Data Pump's export and import (expdp & impdp), and look at the PL/SQL packages DBMS_DATAPUMP and DBMS_METADATA.
