According to the manual, you can configure them to be connected apparently without wires. I believe it does the route internally, but I can't really tell from the manual. There is probably a better manual because I seem to be seeing just the overview, bur it does appear to not need any

Python SDK for z/OS 3.11 is zIIP eligible

Starting with IBM Open Enterprise SDK for Python v3.11 with APAR PH52983, when accompanied with z/OS 2.4 or 2.5 APAR OA63406, Python applications will become eligible for execution on zIIP processors as described in https://www.ibm.com/support/pages/authorized-use-table.

Tom, This reminds me of the VSAM-XA almost disaster of the early to mid 1990s. Let me make this short and sweet. IBM called a meeting of developers in San Jose. DFP said what they were wanting to do with VSAM-XA. I brought to the manager's attention (I think it was Yates) that the

Thank you all for your input! The reason for the question is that IBM is consdering removing the CHKPT macro and is wondering if it is used much. The COBOL runtime uses CHKPT for our checkpoint/restart functionality, I think DFSORT does as well, and also Broadcom's Smart/RESTART facility. There

Unfortunately, the ignoring of low-end processor client needs is just a reflection of the Armonk attitude and position that only high-margin business is worth IBM's attention. No concern for growing smaller clients into larger ones at all. I have never understood that attitude, as it seems to

Note on GBP duplexing: Not duplexing, to my understanding, would force a DB2 group restart after a CF failure. On the other hand, duplexing GBP's can be expensive. Fortunately, IBM introduced asynchronous duplexing which saves quite a bit of CPU. You just have to make sure your z/OS, CF

As you have observed, there is no support for "PSW". I'm curious what SLIP trap you're setting that would let you even know to look at "+4". You'd have to know that the instruction itself was a branch and that it was one of "your" branches. If you really could tell that it was one of your

I presented – briefly – on this yesterday at the Munich Resilience/Resiliency conference. Yes, SMF 74-4 tells you what IS – and perhaps tells you stuff to make you resize structures. To the point, though: You need to think through the scenarios – both for memory and CF CPU. For example, you
