Re: z/OS 1.4 Running on 9672 CPU
You can't order 1.7, but they can migrate to 1.9 with no problems. As I have pointed out numerous time before, I've had no problems at any of the client sites jumping more than the IBM recommended migration jump. In this particular case, they can probably pick up a used Z/series box and convert on it and pay for the new hardware with what they will save by dumping the 9672.

Re: z/OS 1.4 Running on 9672 CPU
Jason, For reference, your 9672-Z87 has a full capacity software rating of 217 MSUs. That's a relatively large machine, and I would strongly recommend running the financial numbers immediately on getting to a 64-bit machine. Every month your employer is paying full capacity (217 MSUs) for z/OS and all other software. This is especially problematic if you have more than one LPAR and could be running middleware selectively by LPAR. For example, if you only need a little bit of IMS, you're currently paying full capacity pricing for IMS instead of paying a price for just a smaller LPAR's worth. You're also missing out on as many as 3 technology dividends, which are MSU reductions for equivalent capacities. The good news is the migration shouldn't be particularly difficult and doesn't involve a lot of steps. You have some not-so-difficult routes available which I will sketch out for you. Please talk to somebody (like IBM) about it ASAP. ** Path #1 ** 1. You could move to a 2094 model (System z9 EC) -- possibly a used machine if it makes sense and if it is available -- and keep your operating system and middleware the same initially, running z/OS 1.4 in Bimodal Accommodation mode (ESA 31-bit mode) for up to 12 months if necessary. Since there are no software changes (except maybe a z/OS PTF or two), you can accomplish this hardware-only migration very quickly indeed. You'll still be charged full capacity as long as you run in 31-bit mode, but you could get, for example, a 2094-408 model which should be about the same performance as your current machine yet only require 185 MSUs of software. I think the 408 would also have the same number of engines as your current machine, so if you're happy with that then there's not too much thinking involved. 2. Start sending in SCRT reports. Get your z/OS 1.4 IPLed into 64-bit mode. When you do that for every LPAR, and once IBM has a couple months of SCRT reports from you, you can start enjoying sub-capacity VWLC pricing for your software. You will also enjoy storage relief: the 2094 comes standard with at least 16 GB, and you can assign all of it (except HSA) to z/OS with 64-bit memory addressing. 3. Migrate to z/OS 1.7 (and the latest middleware product releases), which you can do with coexistence and fallback on the same machine in new LPARs. 4. Consider adding zIIPs or zAAPs at this point if your workloads could benefit. (IFLs may also be useful.) 5. Once you've migrated to z/OS 1.7, consider upgrading the machine to a 2097 (System z10 EC), likely a 408 model again. The 408 model will have more capacity than your current 9672 machine, but it will drop the full capacity MSUs again down to 180. You can perform this upgrade and keep the same serial number as the System z9 EC if you wish. 6. Keep staying current, with your next step up to z/OS 1.9 (now available). ** Path #2 ** 1. If you're not growing very fast, you could move directly to a 2096 (System z9 BC) machine. Your current machine is up near the top of the range of capacities for the z9 BC, but it does fit. For example, a Z03 model will probably give you just a little more capacity but have a full capacity software rating of only 189 MSUs. I believe you can run z/OS 1.4 Bimodal Accommodation mode on this machine. This machine will have fewer engines, however, so you'll want to make sure it makes sense for your workloads. 2. Same as step 2 above, except that the 2096 arrives with a minimum of 8 GB of memory. 3. Same as step 3 above. 4. Same as step 4 above. 5. Same as step 6 above (skip step 5 above). In short, in addition to the out-of-support concerns, the financials probably don't make any sense for you to keep the 9672 machine. Let somebody run the numbers (including an ELA I'd recommend) and please get moving, now. Good luck. - - - - - 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

Re: z/OS 1.4 Running on 9672 CPU
I assumed the original poster's employer had done the right thing and ordered z/OS 1.7 at some point in time. Perhaps that's a bad assumption. Regardless, I would strongly recommend he ring IBM as soon as possible. - - - - - 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
Re: z/OS 1.4 Running on 9672 CPU
My question is - I thought that starting z/OS 1.2 and above, expanded storage is all gone and running in pure 64-bit?? Up to 1.5 (iirc), there is/was bi-modal support for z/OS. So, 31-bit still works with 1.4. - Too busy driving to stop for gas! -- 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
Re: z/OS 1.4 Running on 9672 CPU
Hi Ted, Thanks for the prompt reply. I have another question, if we have central storage constraint, can we increase the central storage to more than 2GB? Or should I need to do something else to be able to do this? I am not sure whether the 9672-Z87 allow 64-bit.

You need to be on a z/900, or later, machine and on OS/390 2.10 (or z/OS) to run 64-bit. Otherwise, you can only support 2GB of Central. - Too busy driving to stop for gas! -- 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
