The System i Strategy for New Customers
** This thread discusses the article: The System i Strategy for New Customers **
Joe, Your paragraph beginning with the JVM running in the 128-bit address space kind of left me in the dust. I couldn't follow it. But if you believe you could write a more efficient database interface, then more power to you. AFAIK, Java RLA uses the same Host Servers as JDBC. RLA is part of the Toolbox. Following is an introduction to the Tookbox from an IBM Web site: "The IBM Toolbox for Java provides support similar to functions available when using the Client Access/400 APIs. It uses the OS/400 host servers that are part of the base OS/400 operating system to access data and resources on an iSeries or AS/400 system. Each of these servers runs in a separate job on the server, communicating with a Java client program using architected data streams on a socket connection. The socket interfaces are hidden from the Java programmer by the IBM Toolbox for Java classes." AFAIK, all interfaces between Java and native services go through Host Servers, although I seem to recall reading about an optimized interface that didn't use sockets, but the optimizations turned out to be trivial. Finally, I don't know Blair Wyman or what he may have said about the new 32 bit JVM performance, and would prefer not to call him a liar, as you suggested, but would rather give him the benefit of the doubt. I'm mostly having a hard time reconciling IBM's earlier statements about implementing the JVM below the machine interface, with newer statements about implementing the 32-bit version under PASE. Google on "webfacing comparable 5250" and the first hit is a post by IBM's David Slater stating among other things that the Webfacing interface and the 5250 interface have comparable performance. I recall a number of similar statements, but didn't bother saving references. http://search400.discussions.techtar...@@.ee84638/565 I've read a lot of information over the years, mostly from IBM about Java performance. In every case the comparison between Java and ILE performance is ignored, side-stepped, or trivialized to the point of meaningless. We kind of veered off topic. I was just hoping to gather a bit more information about PHP on the iSeries.
