In 1965, Gordon Moore observed that integrated circuits were taking less and less space at a geometric rate, an observation that came to be known, in various forms, as Moore’s Law. In 1966, the original Star Trek TV series began each episode with, “Space, the...
Container Pricing, which was introduced in late-2017, is a new pricing solution that makes scaling workloads more economical. Container Pricing is a framework for hosting simplified and flexible software pricing for qualified workloads running on z13 or z14...
Mainframe users have a problem: finding people with the right skills to service their mission-critical systems. It isn’t language: learning COBOL and PL/I is relatively easy. The difficult part is understanding the logic of systems built by programmers who...
The Mainframe Era In 1970 I joined a company, Databank Systems Ltd, that operated a national network of 6 computer centres, each containing a S360/40. In total this was less than 1/10,000th of the power of my current laptop, at a cost several thousand times...
In Application Architecture: an Evolutionary View I wrote of the way that computers have evolved from the mainframe era of the 1970’s to today’s interconnected world, where mainframes and other servers communicate with PC’s and mobile devices to provide services that...
Db2 12 is classified as an in-memory data base by Gartner. It is not just a simple in-memory data base but a very smart one. In this paper, we explain one of the most innovative in memory optimizations in Db2 12. Why In-Memory Optimization in Index? The...
As the size of database and the volume of transactions increase, many of Db2 transactions tend to spend significant amount of wait time in database read and log write I/Os. zHyperLink is introduced to help reduce b2 transaction latency. zHyperLink is a new short...
Last week we ended with Db2 Performance of zHyperLink Read. Now let’s look at the CPU cost of zHyperLink read. As explained last week, I/O operation is now synchronous to CPU with zHyperLink and SQL processing spins while waiting for the I/O to complete. At the same...
For the first time ever, we have five generations in the workplace at the same time. This is most profound in a technology like the Mainframe. Fortunately, today a lot of Organizations realize the importance of training the millennials with the aging mainframe...
Google, Facebook, and Twitter own giant data centers all over the planet, and they are built with racks of commodity hardware. If thousands upon thousands of small servers networked together are good enough for Google, Facebook, and Twitter, then shouldn’t they be...
