Re: how much difference is between deploying a j2ee application in Z/Os and in windows?
Rob Wunderlich writes: z/OS DB2 tends to lag behind Windows in function. Check which version you are running on z/OS compared to the Windows version. Just to expand on what Rob is saying, if you're running an older version of DB2 for z/OS, then Rob's concerns likely apply. However, a lot has changed concerning DB2 for z/OS in the past couple versions. If you draw a Venn diagram, there's mostly overlap, but the area outside DB2 z/OS (and inside DB2 Linux/UNIX/Windows) has gotten smaller (and continues in that direction), and the area outside DB2 LUW (and inside DB2 z/OS) has been getting a bit bigger lately. There are a lot of reasons for these trends, but that's a topic for another thread. There's a great bit of documentation, SQL Reference for Cross-Platform Development, which I would recommend for developer audiences. You can find it here: http://www.ibm.com/developerworks/db2/library/techarticle/0206sqlref/0206sqlref.html Hopefully this book will get updated for DB2 Version 9 very soon, but the DB2 V8 guide is quite valuable. I think every developer who writes code that accesses databases should have a copy of this book close by. As a general rule with WebSphere applications, it's not too hard to redirect them from using DB2 V8 LUW (or earlier) to using DB2 V8 for z/OS. Or V9 to V9 (and often even V9 to V8). Yes, it's something you want to think about and plan, but, in general, it's not a particular challenge. Actually, I think in an earlier thread I alluded to the fact that mainframes measure and monitor, and that alone can be a shock for developers with code that hasn't been previously measured and monitored. If the code and/or database-related logic is inefficient, you can still run it, but the mainframe will tell you exactly where it is inefficient. And that alone can be a blow to many developer egos. :-) Just make sure you understand and prepare for the psychology involved there. :-) - - - - - Timothy Sipples IBM Consulting Enterprise Software Architect Specializing in Software Architectures Related to System z Based in Tokyo, Serving IBM Japan and IBM Asia-Pacific E-Mail: [EMAIL PROTECTED] -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html

Check which version you are running on z/OS compared to the Windows version. In my experience, as long as you are doing basic SQL stuff, it ports fairly well. I don't use Windows DB2 but I frequently develop J2EE apps using MySql on the desktop and deploy to z/OS DB2 for production -- no problem. -Rob -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html

Thank you. What is the volume of web hits you are expecting? I would not think clustering and load balancing would be any different. Clustering is done through the admin console, so it should be the same. Depending on your user group and the required app availability, you might not need to cluster. As for the DB2 questions, I do not work with DB2. That is a different group of people here.

how much difference is between deploying a j2ee application in Z/Os and in windows?
Hi thank you for reading my post. Can some one please let me know how much different is between deploying an application into websphere application server installed in Z/OS and an application server installed in windows or linux? What are the main area of risks when we migrate from windows to Z/OS or Z/Linux? Also, what are main risk area of moving from windows and DB2 to Z/OS and DB2?

Thank you. I am not familiar with the Windows version, but I know that the same ear that can be deployed on AIX can be deployed on z/OS with no changes. I have done this before. The admin console for WAS 6.x is mostly identical on either platform. The only risk I know is that you might get better reliability with the z/OS version.
