1) Editorial

September was the month of Jewish holidays.

Now that it is over I’m back on track. We hope to see Informix 14.1 in a few months.

Yes there are plans for a major new version. Like hotels and other vendors Informix will go from version 12 to version 14.

Hope to meet you at the IIUG World in Washington DC October 28 to November 1.

2.1 Promoting the vnext Early Access Program

Informix is looking for clients that want to directly influence our innovation. In early November we are kicking off our Vnext Early Access Program (EAP) where you can explore the new features in our next major release and provide input on those features including performance, security, and IoT enhancements. In addition, we are looking for Design Partners who will work closely with us in the design and development phases of our key innovation items. Please contact us if you want to hear more of how you can help us help you!

4) RFE Corner

IBM created a public website to collect the requests for new features directly from users. The RFE (Requests For Enhancements) website is included in developerWorks. You can access it here.

Once you logged in with your usual IBM ID, choose “Information Management” in the Brand dropdown box and “Informix Servers” or “Client Products” in the Products dropdown box.

The idea of the RFE corner is to provide a digest on new Informix RFEs and make those RFEs more visible and accessible to the community, so you can vote on those that are also important to you. By actively participating in this website, IBM will have solid and useful elements from the customer base to introduce new functionality to Informix product.

Also in the area of IBM website, a new functionality has been released: MyNotifications. You will want to register this webpage in order to receive the notifications of your choice (new product defects, new patch release, new versions etc…, on the frequency of your choice (daily, weekly). I have registered and will definitely remain registered, due to the value of the information delivered.

Check at this place.

You can access each RFE by clicking on the above links. At the bottom of each RFE page you will find a hyperlink to vote for it. You will see the Request stats, including number of votes for this request, on the right side of the request page. The more votes, the greater the chance an enhancement will be addressed by the Development Team.

6) Works for me

In this section I will write about things that help me in my day to day work. Most DBAs probably have their own ways to perform these tasks which may be different than the way I do them. So, if you find an error or can think of a better way, please let me know. If not feel, free to use these tips as is or modify them to fit your needs.

We write SPL routines for many purposes. The problem is to keep track.

This SPL routine searches for stored procedures to find out if they are called form views, triggers or other stored procedures.
