If you can reduce your EE license costs by even a single CPU, you've made your effort worthwhile. The fact that the database resides on a user's desktop does not mean it has "left the building."įor that reason, you could use Oracle Database XE to send out aggregated data so that users can have total control over their data and you, in turn, reduce the load on your enterprise hardware. You can schedule purges and refreshes (push or pull) for your customers. With the 4GB disk-space limit in such an environment, you won't have to worry about runaway data. The Aggregation AngleĬonsider the example of a data warehouse environment. (That's why you pay for an enterprise license.) Oracle Database XE is designed to store only a useful subset of that data.Īs you'll learn in the next section, these limitations can actually work for you, not against you, for everyday DBA tasks. Even accounting for JOBS, DEPARTMENTS, and the other sample tables, you would not want to store that much data locally. That means you could store almost 30 million employee records. The maximum row size of the EMPLOYEES table is 144 bytes. Sure, compared to a multi-terabyte data warehouse, 4GB seems small-but in reality it's hardly that.Ĭonsider the included HR sample schema. However, 4GB is a huge amount of storage for most applications. Instead, Oracle uses the concept of schemas to separate applications.įinally, a 4GB limit is enforced on disk space-which on its face appears to be serious limitation. The important point here is that you don't need a database for each application you create, as you might for some competing databases. The third limit is that only a single XE database can run on any given computer. Again, for the uses discussed here, one CPU is more than enough. For that functionality, you need to purchase Oracle Database Standard Edition or Enterprise Edition. Rather, XE will run on a computer with more than one CPU, it just won't scale up to use those CPUs. That does not mean that it won't multi-task or that it can only perform a single function at a time. The second limit is that XE will only use one CPU. For most purposes Oracle Database XE will be deployed to a single user desktop or small workgroup server, so 1GB is more than enough. But when you consider the relative rarity of machines that offer 1GB of memory (especially in small businesses), this limitation should mainly affect how many users can access the database concurrently and, to a certain degree, how well it will perform when those limits are hit. The first limitation is memory-Oracle Database XE can address only 1GB of RAM.

In order to make this release easy to install (e.g., via the standard Windows Installer), configure, and maintain, Oracle has built certain limitations into the product. But before we begin, it's important to understand Oracle Database XE's inherent limitations. In this article, I will overview some of the obvious as well as less obvious ways Oracle Database XE can add value for these three roles. If you are a developer who yearns to learn "DBA" tasks or just wants an R&D database to try out new things-or if you're simply tired of open-source incompatibility and migration issues when your application needs to scale-Oracle Database XE is your best alternative.įinally, if you are a business analyst who needs to play "what-if" but can't do what you need in your warehouse or application of choice, Oracle Database XE can augment your spreadsheets and models and give you reliable, secure access to the data you need. Deploying that product can also offer a solution to the common problem of users or developers downloading and installing open-source databases, which leaves you with a minefield of maintenance, support, and security headaches. Specifically, if you are a DBA and have users who want to play "what-if" scenarios in your database, Oracle Database XE enables a strategy whereby you can push data out to your user, where it does the most good (and your servers the least harm).
Rather, it will bring value to DBAs, developers, and analysts in the course of their everyday jobs, regardless of the size of their business.
Oracle Database XE's value is not necessarily limited to novices, students, hobbyists, or small businesses, however it also holds appeal for many other situations.
This release is truly a historic one from Oracle.

Unless you're doing your best to avoid the news, you've probably heard about the production release of Oracle Database 10 g Express Edition (XE), a free starter database for DBAs and developers. Oracle Database XE's value is not necessarily limited to novices, students, hobbyists, or small businesses-it also holds appeal for many other situations.
