A Simple Example of Oracle Analytics: Running Totals

articles: 

Analytics are magic. But as with most software products; I seem to use only one percent of the features, ninety nine percent of the time. Indeed, having built warehouses and reporting systems for the last eighteen months, I look back and see that I got a lot done with only three Analytics, SUM, LAG, and LEAD. Knowing how intimidating Analytics can look to those who have not used them, I figured I’d show the uninitiated, how to get in through the back door, with a reduced look at the capability. You can do a lot with very little. We are going to discuss just one Analytic, SUM used to create running totals.

Example of Data Pivots in SQL (rows to columns and columns to rows)

articles: 

My current client has the crew here doing a good deal of data pivoting in migrating data between several Oracle Systems. I figured to turn some heads in a code review by providing a solution for data pivots which is not based on "locally favored" traditional 3GL coding practices but instead employs what is to me the more natural way of doing it for an Oracle database. I was right, heads did turn. Since I now have to document it, I figured why not post it on OraFAQ once and then tell them its online, come here and read it. So this is an example of pivoting in SQL.

Oracle-Bashing

Aside from a nine month excursion to Sybase IQ, I've spent my entire career working with Oracle, so I don't profess too much expertise - indeed any! - about other RDBMS technologies. So in a weak attempt at self-education, I recently accepted an invitation to listen to a Teradata presentation directed at application developers.

An Introduction to ANYDATA

articles: 

My newest project needed to create a record keeping component that would keep track of balancing results over time. Sounded good, meant my customers could look back over time to see how things went, and it provided persistent evidence of good results. I figured on adding two routines (save/get) to a logging package already in existence to save balancing data via an autonomous transaction and retrieve it when needed. But in writing these routines it dawned on me that they would destroy the reusable nature of the logging package. Finally, a real life use for ANYDATA.

Simulating ASM with 10g Database by faking the hardware

articles: 

Caution: This method is for Testing & Learning purposes only.

Most of the Oracle 10g databases are using ASM for storage as it's very simple to maintain the storage w.r.t. to Disks, Datafiles etc.

Flashback Database: A Primer

articles: 

Introduction

Oracle 10g’s brilliant alternative to database point in time recovery is the the Flashback Database feature. With this feature in place you can do almost everything that you can with point in time recovery, without actually having to go through all the disruptions and hassle that a PITR necessarily entails.I recently had a first hand opportunity to see the power of this feature, when I ran a scriptfile to drop tables and unwittingly dropped one of the tables containing sensitive information belonging to my employer Creative Infotech. I later recovered the table and was amazed at seeing how easy it had become to get back dropped objects in Oracle 10g, especially Release 2. Below is a simplified version of what I did

Failover and Load balancing in Oracle

articles: 

Advanced features of Oracle Net include failover and load balancing. These features are actually interrelated in as much as you usually don’t have one without the other. While they are mostly used in a RAC environment, they can be set up in a single instance environment as well.

FAILOVER:
In the context of Oracle Net, failover refers to the mechanism of switching over to an alternate resource when connection to the primary resource gets terminated due to any reason. Connection failure may be broadly categorized as:
