Oracle vs DB2: Which one is easier to use?

Leon Katsnelson — Tue, 27 Sep 2011 05:10:29 +0000

Wikipedia defines Autonomic Computing as follows:

Autonomic Computing refers to the self-managing characteristics of distributed computing resources, adapting to unpredictable changes whilst hiding intrinsic complexity to operators and users.

Simply put Autonomic Computing makes complex systems easier to operate. Both IBM DB2 and Oracle database claim to be easy to operate. Join the next free Chat with the Labs webinar with Burt Vialpando and Rav Ahuja on September 29 to take a detailed look at the autonomic capabilities of DB2 and Oracle. Past webinars in this series have been oversubscribed so register now.

WebSphere CloudBurst Appliance – A Vending Machine for IT

Raising the bar for enterprise IT

There is no doubt that cloud computing has put a lot of pressure on IT organizations to find a way to reduce costs and, more important, bring agility to business processes. Line of business users are increasingly bringing expectations from their consumer experiences to the front door of IT. The thinking is that if it takes a few minutes to get a Gmail account and it is free, why does it take weeks to get an Exchange account on a corporate email system? In an organization of any size, it takes weeks if not [...]

All the IT that a small business or a branch office needs

Leon Katsnelson — Fri, 15 Jan 2010 23:50:17 +0000

In the past year we have spent a lot of effort putting DB2 on the cloud and we achieved absolutely fantastic results. Db2 has proven to be a hit on both the Amazon cloud, on RightScale and on the IBM Developer Cloud. But all this focus on running applications on the rented IT infrastructure in the cloud does not mean we don’t care about people who want to have their own IT equipment. The free DB2 Express-C is a good fit for small and medium business and an even better fit for remote offices of very large enterprises. But, let’s [...]

DB2 Express-C helps Russian ISV improve performance 5-10 times

Leon Katsnelson — Wed, 23 Sep 2009 22:14:32 +0000

If you spend any time in the fast growing Russian IT market there is one name you will no doubt be familiar with. I am not talking about Microsoft, Oracle, HP or even IBM. A company with a very short name “1C” is an icon of the Russian IT economy. Founded in 1991, 1C helped the newly formed Russian companies to get proper accounting and other financial management footing to be able to compete on the local markets and to enter and, in many cases, lead in the global economy. 1C is a major software distributor and an award winning game developer. If you like combat [...]

The Article every DBA should forward to SQL developers

Leon Katsnelson — Tue, 08 Sep 2009 18:41:08 +0000

I think that every Database Administrator needs to read the article “Opinion: No more excuses for SQL injection attacks” and send it out to every application developer they know. I hate SPAM as much as the next guy but I think it is justified in this case. I am dead serious. We, the database people of all walks of life (DB2, Oracle, SQL Server …), have been talking about the benefits of using parameters in the queries instead of literal values for years. The main message has been “performance”. Most DBMS will perform much better and will use less server [...]

Cheap storage just got even cheaper

Leon Katsnelson — Thu, 16 Oct 2008 02:54:10 +0000

When a database person mentions storage, images of cabinets full of disk drives and cables come to mind. But, since in my recent post I promised to talk about cloud computing I figured I’d talk about a different kind of storage. I am talking about storage that you can’t see or touch; I am talking about storage in the cloud. When Amazon (the people that sell us books and CDs) launched their web services AWS, S3 was one of the first services to go online. S3 stands for “Simple Storage Service”. Amazon built out a very significant IT infrastructure to [...]

Free e-book on getting best performance for DB2, SOA environments, and XML applications

Leon Katsnelson — Tue, 16 Sep 2008 04:18:00 +0000

DB2 Express-C comes with XML and Web Services support already backed. There is a free e-book from the experts in all things DB2 that supposedly helps you get the most out of these functions. The author of the section on automatic maintenance and utility throttling, Roger Sanders has written enough books on DB2 to fill a small library. If you ever decide to prepare yourself for a DB2 certification, you will most likely be using one of Roger’s books. Robert Catterall contributed the chapter on SOA performance. Robert has been working with DB2 since the dinosaurs roamed the earth (or [...]

Everything you ever wanted to know about a DB2 table but did not know where to look

Leon Katsnelson — Wed, 16 Jul 2008 04:29:52 +0000

Since table objects (or just tables) are so fundamental to your ability to store and retrieve data there comes a time when you want to get some information on a particular table in your database. For example, you may want to know how much disk space has been allocated for a particular table, or what state it is in. Should it be reorganized? Has the last load job finished loading data in to it and so on. If you were using MySQL, you may have just looked at the file that represents a table and were able to figure out disk usage that way. There is a better way to do this in DB2 Express-C (and every other DB2 for Linux, Unix and Windows v9.5). Since DB2 speaks SQL, it makes sense to query information about its tables using SQL. DB2 provides not one but 2 ways of getting cornucopia of information about tables via SQL. One way is to use a SYSIBMADM.ADMINTABINFO view. [...]
