You’re an IBM mainframe user, where can you go for help with your mainframe problems? (If you were thinking of more personal problems, you’re reading the wrong blog!!) Well, my obvious answer would be Xephon’s Update publications (see www.xephonusa.com) or, perhaps, a search on Google (www.google.com), but IBM has recently introduced Destination z (http://www-03.ibm.com/systems/z/destinationz/index.html).
IBM’s new Web-based portal is designed to allow its customers, system integrators, and software developers to talk about mainframe usage, share ideas, and ask for technical help from other users. And just in case you might find you need to buy something, Destination z has links to IBM sales. To be fair, though, it is meant to contain technical resources such as case histories and mainframe migration tools. Part of the thinking behind this development is to provide the expertise to help potential customers migrate workloads from other platforms to mainframes.
In marketing speak, the IBM announcement said that it will also provide space for business partners to drive business developments and provide a broad spectrum of technical resources.
Going back to Xephon, for a moment, the June issue of TCP/SNA Update shared some interesting ideas from mainframe networking specialists. There were two articles that included code that could be used in order to monitor and measure exactly what was going on. The first looked at VTAM storage utilization and the second looked at VTAM subpool storage utilization. A third article looked at the need to apply a PTF if you utilize the VTAM Configuration Services Exit. There are also two interesting articles. The first talks about SNA modernization, and the second discusses Enterprise Extenders.
If you have some mainframe networking information you would like to share you can send your article to me at firstname.lastname@example.org.
