Re: APF authorization and AC(00)

A REFR program's page can be stolen (without having to save it first) by the RSM if it has a higher UIC than other pages. If it then hits a page fault, the ASM reloads the missing page from the paging dataset so the program can continue executing. AFAIK It reloads only stolen pages, not the whole m

Re: Estae and the Linkage Stack

It is a little tricky. In the Assembler Services Guide there is a section called Linkage Stack Considerations in chapter 8, the last paragraph of which says: When you issue a PR, the system automatically deactivates all ESTAE-type recovery routines that were previously activated under that curr

I have a number of applications that sort a REXX array. My solution is to load it into an ISPF table. Not only is a table easily sorted, but you can do an instant search with single ISPF command. And so much more. Yes, you need to run in a TSO environment, but I've never found much use for a R

There are several things intertwined here. * CPACF is the "crypto on the chip" - z Systems instructions that do AES et al. * CEX is the z HSM. * ICSF is, of course, the z/OS service that talks to both (though you can do CPACF operations directly as well). With just CPACF, y

Re: changing batch job to use SSL

You have laid the ground work to be able to use SSL in your program, however, the next step is the difficult part. You will have to reengineer your application to create the SSL environment and make secure calls. As others have suggested, AT-TLS is the route to follow here. You will be able t

It could be practical when writing high-performance code to modify a RENT module if it is not in key 0 (or use a PC to make the modification if in key 0). An example would be if an extensive chain of indirect pointers (or the NAME/TOKEN service), is used to locate life of IPL memory allocated
