OpenVMS Technical Journal - V12 January 2009

Welcome to V12 of the OpenVMS Technical Journal. As you may know this technical journal is done on a completely voluntary basis and hence our "other work" can take priority. I would like to personally thank the team that makes the OpenVMS Technical Journal possible, you are truly a gift.

In this version you will find many articles that will interest you.

From the OpenVMS engineering group, Ajo Jose Panoor, Dick Stockdale, and Anand Ramaswamy have written a great article on LAN troubleshooting techniques. We have an excellent article from Sushruta Nadig in the OpenVMS storage group on Intelligent Scheduling using Fuzzy Logic in applications, Ravi Uppada's article on Alternatives to HP SNA Server, and Rishi Singhal's article on Installing and Configuring a Wiki engine on OpenVMS. We also have an article on Access Restrictions in FTP from Anand Shenoy of OpenVMS TCP/IP engineering.

Also in this edition, you'll find articles from two of our OpenVMS friends. Bruce Claremont has written an article on how to make life easier by using the /RETAIN=ERROR qualifier and Tim Sneddon wrote an article on Calling OpenVMS Native Routines from Java.

We would appreciate your feedback not only on this issue but the OpenVMS Technical Journal as a whole.

Thank you for your continued support,

Intelligent scheduling using fuzzy logic in applications

Article Title: Intelligent scheduling using fuzzy logic in applications - » HTML, » PDF

Article Abstract: To reduce the bottleneck caused by multiple applications performing specific tasks on the productions systems, some tasks which are CPU consuming or which do lot of IO or require time to complete can be scheduled in intervals, when the load on the system will be very minimal. An intelligent scheduler that has intelligence like humans to distinguish things can schedule jobs automatically based on the kind of the job, CPU consumption, priority and other factors. This will help improving the performance bottlenecks. Introducing fuzzy logic to schedulers will bring in that aspect of reasoning to schedulers in applications.

Calling OpenVMS native routines from Java

Article Title: Calling OpenVMS native routines from Java - » HTML, » PDF

Article Abstract: This article is a brief introduction and tutorial on the use of a collection of tools offered by Kednos intended to make it easier for Java and native code to interact. Although Kednos' primary business is PL/I compilers, the tools described in this article can be used to interface Java with any native OpenVMS language that adheres to the common calling standard.

Author Bio: Tim Sneddon is currently employed at Kednos, the producers of the PL/I compiler for OpenVMS VAX and Alpha and Tru64. As well as developing and extending the tools discussed in this article, Tim has been instrumental in porting the PL/I Run-Time Library to Itanium for translated images. He has also been involved in improving the TIE Run-Time Library and AEST translator. Prior to Kednos Tim worked for Reynolds & Reynolds Pty. Ltd. as a Systems Programmer.

LAN troubleshooting techniques

Article Title: LAN troubleshooting techniques - » HTML, » PDF

Article Abstract: This article describes techniques to diagnose and address OpenVMS LAN problems. These problems can be attributed to setup problems, network configuration issues, faulty hardware, or software bugs in the OpenVMS LAN code. The primary focus is on current LAN devices supported by OpenVMS Alpha and I64. The following areas are covered:

  • Network configuration
  • Application configuration
  • LAN counters
  • LAN buffer management
  • LAN trace
  • LAN setup issues
