Leon, that’s interesting.IBM Explorer for z/OS Aqua (or simply Aqua) is a continuous delivery release train platform that brings together a set of Eclipse-based mainframe development tools and offerings in order to provide z/OS application developers and system programmers an easy way to install, deploy and maintain our IBM Eclipse-based products.Azul Zulu Builds of OpenJDK runs on Linux, Windows, macOS & Solaris on X86. It was just a matter of getting the files on the machine > (installer will not work). As a matter of fact, we did hack Data > Studio a couple of years ago to run on the Mac. Oracle XE: a five years of no progress> Data Studio is based on Eclipse and Eclipse does run on the Mac OS X.Having the same product free of charge and an easier to install product on your own laptop makes for a good learning environment. After all, Oracle XE was based on the same code as the paid (and very expensive) commercial versions of Oracle database. Learning with Oracle XEAt the time of its release, I thought that Oracle XE was a great way for people to gain skill in Oracle database technologies. Does it make Oracle XE a bad choice? Should you worry? I think it really depends on what your intended usage is. It is the same Oracle 10g Release 2 code base and it has now fallen way behind Oracle database. There has been no update to the product since its release almost 5 years ago (Oracle XE was released in November of 2005).After 5 years, I expect Oracle 10g R2 does not have a lot of life left in it and people building new applications are likely looking to deploy on the most recent version i.e. Most developers I know want to have a development environment that closely mirrors their intended production environment. Oracle XE for development and TestIf you intend to use Oracle XE to build applications, I think you will be even more disappointed. In my opinion, Oracle XE’s appeal as a starting point for those who want to learn Oracle has been greatly diminished.
![]() 4GB limit is just a nail in the Oracle XE coffin when it comes to production use. For me, any limit on the amount of data you can store in the database should raise a flag when it comes to production use. Even Microsoft SQL Server 2008 R2 Express Edition increased the limit on the amount of data it can manage to 10GB (from 4GB) and DB2 Express-C never had a limit. 4GB in today’s world just does nto cut it. When you reach this limit, you are in a world of pain and embarrassment. Oracle XE is limited to storing 4GB of data. My Oracle XE obviously does not pass the test so I can’t even run it on my laptop, never mind contemplate its use on a production server. Once they find your system to be affected, you get a chance to patch the products or they get disabled. In our office, IT security team conducts frequent security scans of all systems and compares installed products against the database of vulnerabilities. Would you want to put your application in to production when you know that it has hundreds of security vulnerabilities that you will not be able to address? It s a rhetorical question. None of these fixes are available for Oracle XE users … not one. Oracle XE is based on the code base that had several hundred security vulnerabilities that Oracle has addressed in other editions of its database products. ![]() IBM DB2 Express-CContrast this with IBM DB2 Express-C which has had a constant stream of updates and enhancements. Now, five years later and with Oracle’s acquisition of MySQL, the only words that come to mind when describing Oracle XE are “dead end”. At the time Oracle XE was released I did nto think it was going to become an important play for Oracle. MySQL was eating away the low end while IBM DB2 was giving Oracle run for its money on the top end and Microsoft SQL Server was biting it in the middle. Oracle released Express Edition 5 years ago in an effort to stem the advance of MySQL. And when it comes to application development, it is a perfect fit as it not only allows one to exploit all of the latest features of DB2 at no charge but also provides a transparent path to higher value editions of DB2. DB2 Express-C: a great destination or a first step in to something biggerBy providing access to the same technology as the rest of the DB2 products, DB2 Express-C presents an excellent choice as a learning tool for anyone who wants to gain DB2 skills. Our partners have picked DB2 Express-C and carried it in to the cloud as well. For example, when it came to bringing database capability to Cloud Computing, we launched with DB2 Express-C first on Amazon EC2 cloud, RightScale, and IBM Smart Business Development and Test on the IBM Cloud (IBM Development and Test Cloud). Not only is DB2 Express-C consistently kept at the same level as higher value DB2 editions, we also lead with DB2 Express-C in some cases. If this is not sufficient, you can upgrade your DB2 server up to DB2 Express to take advantage of 4 cores and 4GB of memory. That is twice the resources you get with Oracle XE. You can use DB2 Express-C in production and take advantage of 2 CPU cores and 2GB of memory (your server hardware can have any number of cores and any amount of memory). Not a bad path for something that is free!At this point you are probably thinking that this is a “bait and switch” tactic where IBM gets you hooked with its free DB2 Express-C and then hits you with an outrageous price to move up to the next level. All of it with zero changes to the application while exploiting all of the scalability, reliability, security and performance features. Facing explosive growth and still need more capacity? Move up to DB2 Enterprise Edition or the just announced DB2 Advanced Enterprise Edition and take advantage of all all the hardware resources your server can deliver. 4 cores and 4GB still not enough? Upgrade your DB2 installation to DB2 Workgroup Edition and take advantage of 16 processor cores and 64GB of memory (as of today, DB2 Workgroup Edition will take advantage of 64GB of memory). Yes, you read this correctly DB2 Express subscription is now 2/3 of MySQL subscription price. As of today, we reduced the price for DB2 Express subscription to $1,990. This is a great price if you consider that is what Oracle charges for comparable MySQL Enterprise Gold subscription. To move up from the free DB2 Express-C to a fully supported DB2 Express with its extra resources (4 cores, 4GB of memory) and features (replication, built in high availability/disaster recovery clustering, and backup compression) used to cost $2,995/server/year. Ibm Data Studio Eclipse License For AboutFrom the very beginning its future was tenuous. With Oracle’s acquisition of MySQL it is quite clear that Oracle XE is at the end of its road. I actually like Oracle XE but I like DB2 Express-C more … see point 1I am still biased but I no longer like Oracle XE. DB2 Express can also purchased as a perpetual license for about $6,000.In my original post two years ago I said that However, that is where the similarities end. Just as MySQL, DB2 Express-C is available free of charge and just like MySQL it provides optional low cost support. I will say, however, that with today’s price reduction for DB2 Express, MySQL is at a big disadvantage. I think I will do just that in one of my future posts. I believe that with MySQL replacing of Oracle XE at the low end of the portfolio, it makes more sense to compare DB2 Express-C to MySQL than Oracle XE. And unlike Oracle XE which takes you to a dead end, DB2 Express-C provides a very clear growth path that wil take your application where it needs to be no matter how big its needs to be and how fast it needs to get there. Ios emulator for mac os xGet the free book to help you get started and while you are at it get free tools to help you manage your DB2 databases. But don’t take my word for it, download free DB2 Express-C. The fact that it is owned by Oracle corporation is an accident and the story around it continues to unravel. MySQL, on he other hand, shares nothing in common with Oracle database products.
