(Originally posted 2008-05-03.) I wonder how many of you recognise the terms “READ_COCLASS”, “WARM”, “RFCOM”,”WRITE_DATALIST” and “CASTOUT_DATALIST”. Granted that in that list are two pairs of terms that I believe to be synonymous, but all five are relatively recent enhancements to Parallel Sysplex infrastructure that have a positive impact on DB2 Data Sharing performance (orContinue reading “Misunderstood Coupling Facility Commands”

(Originally posted 2008-05-03.) Tomorrow I fly to Dresden for the annual European System z Technical Conference. It’s at just the time of year when I can decide in my head that Spring has sprung and that Summer won’t be long coming. 🙂 This is a great conference and I always enjoy attending it (and presentingContinue reading “System z Technical Conference – Dresden”

(Originally posted 2008-04-27.) As some of you will know IBM has a twice-yearly “HackDay” programming fest. And the latest – HackDay5 – was last Friday. Couched as a competition it isn’t really… It’s a heck of a sight more cooperative than that. (Else I wouldn’t have got involved.) I’ve participated in all five we’ve hadContinue reading “My HackDay 5 Project – z/OS System Logger Analysis”

(Originally posted 2008-01-28.) We’ve been issued new guidance: Delete SPAM rather than mark it invisible. Disallow posting comments after, say, 30 days. The latter appears to work at the individual entry level. Three of my entries have become particularly troublesome (for some unknown reason). So I’ve set them to “no more comments”. If you findContinue reading “Moron SPAM :-)”

(Originally posted 2008-01-11.) Very few people spend as much time as I do down in the guts of individual SMF records. But for those who do ERBSCAN / ERBSHOW is an invaluable tool… ERBSCAN, issued in ISPF 3.4 against an SMF data set, presents you with a list of SMF records and some VERY highContinue reading “ERBSCAN / ERBSHOW – A Parameter You Might Not Know”

(Originally posted 2008-01-02.) Every once in a while 🙂 I do something really dumb… Thanks to Debra and family for the bath bomb… Rather than throw it in the bath wrapped I chose to cut it open and pour the contents in. The result? Rather like bathing with dead flies. 🙂 And, no, I wasContinue reading “Outstupided – Part Umpteen”

(Originally posted 2007-12-21.) As I’ve mentioned before I’m using Roller’s “Referer URL” page – for my developerWorks blog – to analyse where my blog hits are coming from. (It’s an informal exercise because I can only really work with hits that involve a search engine of some sort – and some 80% of my hitsContinue reading “An Unexpected Benefit of Pornospam”

(Originally posted 2007-12-14.) Occasionally you’ll (hopefully briefly) see SPAM comments on this blog. I’m grown up about this sort of thing and just remove the comments when I see them. I hope you’re grown up enough to cope with this irritating phenomenon as well. But I’ve gotten fed up with having to mark these commentsContinue reading “I’ve A Little Button To Banish SPAMmers”

(Originally posted 2007-12-12.) Thanks to Oliver Robinson for pointing this out to me: In MXG Newsletters Numbers 50 and 51 Barry Merrill discusses MXG / WPS support in what I think is a detailed and fair way. (Oliver, for the record, works for WPC who develop WPS.) Barry and I discussed WPS and MXG overContinue reading “WPS and MXG”

(Originally posted 2007-12-10.) Nowadays – actually thenadays 🙂 but more so nowadays – the value of a web page is related to how well structured it is. Well structured from a mashup programmer’s point of view… As I often say you have to assume that people will want to take your web pages and mashContinue reading “Mashinations”
