Short takes

I'd scribbled down a couple of ideas for a post, but I think I'll just combine them in one of my 'Short Takes'. It's about IBM announcement links, my colleague at IDUG, a z/VSE Live Virtual Class, Raid 5 and 6 are doomed and a zEnterprise FAQ. Here we go.
  • First of all you might have noticed that the IBM announcement page (Offering Information) has somehow undergone a facelift. Nothing that spectacular, but I also noticed that along with this, all my links in previous posts to IBM announcements are no longer valid. Apparently it's a 'ShowDoc.jsp' that has been replaced by 'ShowDoc.wss' in the link. Damn. Damn. Damn. So, any link to an announcement you click on will be invalid. Fortunately I always include the announcement number. But that's a small comfort. So I might be in for some massive updates. Furthermore, many links in the latest newsletter that was sent out last week will no longer work either.
  • I'm proud to tell you that my colleague from RealDolmen Frederik Engelen will be presenting at the EMEA IDUG conference next November in Prague. Subject is 'A DBA's guide to using TSA' (Tivoli System Automation). He's presenting in room Stella on November 16 from 8.30 am to 9.30 am. Abstract of the presentation : "Tightly integrating DB2 with Tivoli System Automation software, IBM added automatic failover capabilities to the trusted HADR database clustering technology. After a quick refresh on HADR, this session will go more in-depth on the inner workings of TSA and its interaction with DB2 to provide you with what you need to know before introducing this in your environment" If you go and see him, give him my regards !
  • I'm a bit too late with this one, but there was a Z/VSE Live Virtual Class today on 'z/VSE V4.3 Support of four-digit device addresses'. You can find all information about z/VSE Live Virtual Classes over here. And of course there will be a replay of this virutal class.
  • Something completely different : check out this interesting blog post from The Storage Buddhist : '3 TB drives signal the end of RAID 5 / RAID 6'. This has everything to do with the growing size of drives, the growing time to rebuild disks and the conclusion is quite simple : " Either way, the days of RAID5 are just about over and the days of RAID6 are numbered also". Just take a look at it, it leaves me puzzled about this. It's really about making future choices.
  • I've written about FAQs before and I think the zEnterprise FAQ is a very nice one. If some one's asking me a question about zEnterprise I always know the answer immediately. Hey, I'm a presales guy, it's my job. Just kidding. So, if you have a question about zEnterprise that's not directly up your alley, this FAQ is the place to go. Or you can ask me of course !

I enjoyed your post. It’s a lot like college – we should absorb everything we can but ultimately you need to take what you’ve learned and apply it.
