Capture Point for SNA Applications

Dear list: I'd like to know if there is a sample (source code) in order to develop a capture point for applications which open and control session with SNA printers (LU1 or LU3). We are starting a project to develop this function and as a good start we just need some tips to code an

I put this question to a SHARE buddy who has a lot more experience in the area than I do. He strongly recommended a PDSE-2 if at all possible in order to avoid limitations in the original, venerable design of PDSE. . . . J.O.Skip Robinson Southern California Edison Company Electric Dragon Team

Re: PDS I/O Performance Improvement

This is a typical CICS tuning opportunity. What to keep and what to make pageable are very installation dependent. If there are vendors they should be able to provide guidance. https://www.ibm.com/support/knowledgecenter/SSGMCP_5.1.0/com.ibm.cics.ts.app

Boy this takes me back - to the Summer of 1990. :-) At the time what I call "The Coffee Table Book" aka the Data In Memory Performance Studies WSC Orange Book was freshish out. One of the studies was VIO to Expanded Storage. It showed CPU cost across the range of data set sizes, relative to

Re: PDS I/O Performance Improvement

Skip, VIO is still a great way to handle small, temp data sets. I've used the method mentioned below where VLF was no help, and LLA Freeze a hindrance, and it works surprisingly well. At less than 1Mb per CYL it’s far from being expensive. Then again, I was a big fan of VFETCH too... Not

Re: SRB dispatching question

What parameters were on the IEAMSCHD macros for the two SRB's? If the LLOCK=YES parm is set on both, then there is your problem. Can you send what the IEAMSCHD macros look like? Chris Blaicher Technical Architect Mainframe Development Syncsort Incorporated 50 Tice Boulevard, Woodcliff Lake, NJ

Re: WLM issue with a proposed solution

On the zIIP point assume most of DB2 DBM1 in V10 and nearly all in V11 is zIIP-eligible. (And, yes, SMF 30 gives you the actual numbers.) And thereby hangs another tale... :-) Cheers, Martin Martin Packer, zChampion, Principal Systems Investigator, Worldwide Cloud & Systems Performance, IBM

Re: SRB dispatching question

IF SRB #1 that is non-preemptable schedules SRB #2 and then does a PAUSE, SRB #2 can still be dispatched. Sorry if I wasn't clear. SRB #1 can't be interrupted to dispatch other work on the processor it is running on, but that doesn't mean nothing else can run. Also, if it stops itself, the

Re: mixed AMODE with HLL | 64-bit to 31-bit

Thanks all. My 64-bit to 31-bit shim assembles just peachy but the linker thinks it's a 31-bit animal. Is there something other than AMODE 64 to tell the linker "yes, this really is AMODE(64)"? Does it matter of it's driven from USS instead of batch? Thanks. -- R; <>< On 04/27/16

I have no experience with the PTF in action. I saw it during APPLY CHECK and decided immediately that I would EXCLUDE it in the real APPLY--which has not happened yet. I think we need some clarification from the RACF folks... . . . J.O.Skip Robinson Southern California Edison Company Electric
