John, let's be precise here. You decided to run SCRT off platform, and that's one choice. But the IBM SDK, Java Technology Edition, Version 8 for z/OS is compatible with/was supported with z/OS 1.13 and higher. (z/OS 1.13 has reached End of Service, so it's an "as-is" situation now.) There are no additional Java 8 prerequisites in terms of machine model, not generalized ones anyway. It's highly likely the error message you observed is spurious since (from what I can determine from afar) you didn't satisfy the published prerequisites. IBM never said Java 8 would work on z/OS 1.12 (your release). When you stray from the published prerequisites and something doesn't work then all you can conclude is that the published prerequisites might be correct. You cannot logically conclude that the published prerequisites are incorrect, and that's what you seem to be doing in what you just wrote. Anyway, back to the original question Nightwatch RenBand asked, or at least a workaround.... Nightwatch RenBand: Likely the easiest, quickest way to solve your particular problem is to install the IBM SDK, Java Technology Edition, Version 8 via SMP/E rather than via the Web-delivered version. The SMP/E installation should get JZOS properly installed into PDS/Es for you (as well as zFS). You can order the SMP/E installable SDK (with the latest maintenance) through IBM Shopz, and it's a no additional charge software product. That is to say if you're a z/OS licensee you can obtain and run this software product at no additional charge. There are actually two products because there are two IBM Program Numbers, one for the 31-bit release and the other for 64-bit. SCRT recommends 64-bit, although 31-bit will likely work especially if you have a relatively small number of LPARs. You might as well order and install both. Here are the IBM Program Numbers to order: 31-bit: 5655-DGG 64-bit: 5655-DGH And here's the link to IBM Shopz: https://www.ibm.com/client-tools/shopz End of Service for these products is currently September 30, 2026. If you need to open a problem case with IBM that's specific to the SDK (a suspected defect in Java) then you probably can still do so, although be prepared for a "Sorry, we've reached our limits" if you start to drift into something specific to z/OS since you're on 1.13. Obviously it'd be wonderful if you get to a newer, supported z/OS release. But SCRT Version 29's requirements shouldn't force you to do so.
