Revealing Centaurus

In the March edition I hope to write about a different Centarus which is the code name for Informix 12. But as I am under NDA all I can say for now is expect a great release loaded with new features. Until Informix 12 is officially announced enjoy the following text from Wikipedia about the Centaurus mankind has been admiring since the beginning of history.

Centaurus contains several very bright stars because of its position in the Milky Way; in addition, its alpha and beta stars are used to find the constellation Crux. The constellation has 281 stars above magnitude 6.5, meaning that they are visible to the unaided eye, the most of any constellation. Alpha Centauri, one of the closest stars to the Sun, has a high proper motion; it will be a mere half-degree from Beta Centauri in approximately 4000 years.

Alpha Centauri is a triple star system that contains Proxima Centauri, the nearest star to the Sun. Traditionally called Rigil Kentaurus or Toliman, meaning “foot of the centaur”, the system has an overall magnitude of -0.28 and is 4.4 light-years from Earth. The primary and secondary are both yellow-hued stars; the primary, is of magnitude -0.01 and the secondary is of magnitude 1.35. Proxima, the tertiary star, is a red dwarf of magnitude 11.0; it is almost 2 degrees away from the primary and secondary and has a period of approximately one million years. Also a flare star, Proxima has minutes-long outbursts where it brightens by over a magnitude. The primary and secondary have a period of 80 years and will be closest to each other as seen from Earth in 2037 and 2038.

In addition to Alpha Centauri (the 3rd brightest star in the sky), a second first magnitude star, Beta Centauri, is part of Centaurus. Also called Hadar and Agena, Beta Centauri is a double star; the primary is a blue-hued giant star of magnitude 0.6, 525 light-years from Earth. The secondary is of magnitude 4.0 and has a very small separation. A bright binary star in Centaurus is Gamma Centauri, which appears to the naked eye at magnitude 2.2. The primary and secondary are both blue-white hued stars of magnitude 2.9; their period is 85 years.

Centaurus also has many dimmer double stars and binary stars. 3 Centauri is a double star with a blue-white hued primary of magnitude 4.6 and a secondary of magnitude 6.1. The primary is 298 light-years from Earth.

Centaurus is home to many variable stars. R Centauri is a Mira variable star with a minimum magnitude of 11.8 and a maximum magnitude of 5.3; it is 2100 light-years from Earth and has a period of 18 months. V810 Centauri is a semiregular variable.

BPM 37093 is a white dwarf star whose carbon atoms are thought to have formed a crystalline structure. Since diamond also consists of carbon arranged in a crystalline lattice (though of a different configuration), scientists have nicknamed this star “Lucy” after the Beatles song “Lucy in the Sky with Diamonds.”

Learn about Informix Centaururs

Even at $1099 this year’s conference is still the best technical conference bargain on the planet. Those of you who are IIUG members (and that membership is FREE) will save an additional $100 from the above registration rate, but that IIUG Member Discount DISAPPEARS on April 1! Whenever it is that you get off your duff and sign up, you will set yourself up to attend the biggest meeting of the minds in the IBM Informix world. Don’t wait, Register now!

The sessions lined up include deep dive views of “Centaurus,” the still secret (oops, not anymore) “VNext” release of Informix. Several of us on the planning committee have been part of the Early Release program for the new version, and its new features bring Informix major steps forward in popular areas including nearly automatic provisioning and configuration, continuous availability and improved extensibility. Other new topics being covered for the release include the use of Recursive SQL and query transformation in the new release, as well as new indexing techniques being made available.

One major change from previous conferences is that the tutorials, being held on Thursday April 25, are included at NO EXTRA COST for all paid attendees. The tutorials will focus on configuration and performance tuning, but will NOT limit themselves to the latest versions but will also cover older versions of Informix, including those no longer supported by IBM (We all know, and many of us still use, Versions 7, 9 and 10)! The list of tutorials will be posted to the Conference website very soon! Don’t forget to select your tutorials when they become available to reserve your space.

We now have the list of sessions (more to come as we get speaker confirmations) and speakers available for viewing on this year’s Conference website. This impressive list of topics is intended to increase or reaffirm your Informix knowledge and skills. We have several new speakers to the conference as well as many of your favorite speakers from past conferences. All have been gracious enough to share their knowledge with the Informix community.

Don’t forget to check out the sponsors for this year’s conference. When you attend the Conference please visit our sponsors and let them share information on their products and services with you. They may have something you have been looking for!

The Conference Planning Committee is looking forward to seeing some old friends and making new friends this year. Hope we see you there!

Government and industry groups have responded by enacting fraud management regulations designed to protect public and shareholder interests. But your business generates enormous volumes of network traffic every day. Tracking and sifting through all user activity for abuse, misuse, and error can feel like an impossible task. Fortunately, technology exists to help you overcome these challenges

Continuous monitoring is the key to knowing exactly who did what and when – then being able to put that information into context. Take 3 bold steps and start to monitor and manage risk within your legacy mainframe applications, web applications, and across the enterprise. These three steps, deliver the intelligence you need to take informed action for auditing, compliance, and general risk management purposes.

How to find the application that’s running a particular SQL?

It is not uncommon that an inefficient SQL statement causes overall performance problems. In that scenario, first you need to identify the problematic SQL, next find out the user and application that executing the SQL. Here is a glimpse to address the second part of the problem.

There are different possible ways to find out the user and application running a particular SQL. The ‘onstat -g ses <sessionid>’ command is the simple way figure out the application that running a SQL. Do you notice anything new in the following ‘onstat -g ses <session id>’ output?

First you are creating a procedure under ‘sysadmin’ database named ‘delete_apb_documents_proc()’ that removes all files as ‘apb_document*’ from /tmp directory which were accessed more than 60 minutes ago.

You are right. There is a new ‘Program’ section in above onstat output. Now, you can use the ‘onstat -g ses <session id>’ command to display the full path of the client program that used in a session. Use the client program information to monitor or control the application access to the database. One thing you should know that the program information is sent by the client itself, and name of the program totally depends on the client.
