Hi Gadi, I'm going to give you some information. I'm not sure any of it will necessarily help you, but at least you might be able to know what some options are. You might already know this, and I apologize if I'm repeating information you already know. There will not be any silver bullet, or necessarily happy news here for you - I'll warn you.
1. As you see, it will be increasingly difficult to run any relatively modern z/OS workloads at a reduced cost without a zIIP. I would include anything Java related in that category. So, z/OSMF is definitely included. We are becoming more and more dependent upon it for management of and certain functions on the system, and therefore more reliant upon usage of zIIPs. I would hope that your enterprise is aware of this, having taken a business decision not to currently have a zIIP, and what that means to z/OS. 2. There are some minor tweaks you can do the help with the performance on z/OSMF start up. They've been discussed here several times, but I'll point you to a performance paper where an IBM Performance Tester has done an evaluation. https://www.ibm.com/support/pages/system/files/inline-files/zosmf_v2r4_resource_requirement.pdf In addition, I know that Frank Kyne has done his own deep dive into this topic. He will be presenting at the z/OSMF Guild on just this topic, if you wish to join and see if he has any pointers you might not be aware of: https://community.ibm.com/community/user/ibmz-and-linuxone/blogs/rolando-perez/2021/11/03/zosmf-guild 3. As you upgrade your HW server level, you will hopefully get to the z15 eventually making your z13 situation not a long lasting situation. This is where System Recovery Boost will give you at no cost, the ability to have an IPL boost on your subcapacity machine to run full speed with a Speed Boost. This will allow you to initialize z/OS and z/OSMF faster for 60 minutes. Once you have z/OSMF initialized, the consumption of the z/OSMF server does flatten out considerably. 4. Do note that until July 10, 2022, you can get that CustomPac for z/OS V2.5 that you can still install without z/OSMF. If your upgrade plans do intend to upgrade to z/OS V2.5, I would order and download it now, so that at least you have a copy of it that doesn't need z/OSMF to install for the time being. 5. I'm seeing that there are few options left at this point. I can think of only two: you could install with a CBPDO yourself, which will be time consuming and cumbersome, and which itself will drive a lot of General Purpose cycles. Or perhaps you could hire an outsider to use their own systems to install and provide you with a dump/restore format. I wouldn't know, but I would hazard that the cost of either of these might be more than the price of a zIIP (but I know nothing of the costs). I do wish that you are able to find a solution that will work for you. -Marna WALLE z/OS Installation and Upgrade IBM Poughkeepsie ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
