Editorial Back to top

The 2015 IIUG conference is over and we are already thinking about 2016. Where and when are still in the works, but it will probably be early May and somewhere that is not on the west coast. Currently we are not even sure we will have a conference. But I believe and hope we will. The conference is important not just for the Informix community but for the Informix product as well. I was hoping to meet more of you in San Diego. If you have any ideas how to get more attendees to our next conference please let me know.

IIUG 2016

The IIUG Conference Planning Committee would like to thank everyone who attended IIUG 2015. It is always great to see old friends and make new friends. We hope you returned home with stronger Informix skills and you picked up some new ideas to take back to work.

We are reviewing your comments from the IIUG 2015 evaluations and will use what we learn to help us make IIUG 2016 an even better event. For those of you who have begun your long range planning, we want to let you know IIUG 2016 will not be the last week in April as it usually is. It will most likely be held during the beginning of May.

We are looking forward to seeing you in 2016!

A ‘sort of’ answer

Once in a while, Support is asked to help determine: “What session is generating all the temporary sort files?” There is no onstat command to answer this, but it can be done in a couple steps:

  1. Turn on syssqltrace. Make sure you capture enough trace lines. The value for “Number of traces” in the output of ‘onstat -g his’ should be under the number of traces you specified, while enabling trace. If ‘onstat -g his’ shows the number is beyond the value you specified when enabling tracing, it could miss capturing some of the queries that ran.
  2. Identify queries that need disk sort space:

    select sql_totaltime, sql_statementfrom syssqltrace where sql_sortdisk > 0

RFE Corner Back to top

Just in case you are not aware, some time ago 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 interesting thing is that any request, including your request, if you place one, are submitted to be voted on. This means the RFEs that receive more votes have a greater chance to be considered by the architecture and development teams for further consideration. In other words, this IS the opportunity to provide enhancement ideas even if you are not the biggest IBM customer on the planet Earth.

Some RFEs will be of great interest, others will not seem useful to you. This is why your opinion is important. Do not hesitate to vote and place comments!

The idea of the RFE corner is to provide a digest on new Informix RFEs and make those RFEs more visible and accessible for the community, so that you can vote for them in a faster and easier way. By participating actively 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 keep registered, due to the value of the information delivered.

Register here.

Annual IIUG features survey

Before checking this month’s list, do not forget to complete the annual IIUG Features Survey that we have created for you. This survey is a summary of this past year’s most significant new features requests from the RFE website for Informix products.

By casting your vote for your favorite Informix new features, you will give extra momentum to those RFEs and contribute to turning them into actual Informix features.

This survey should not take you more than 10 min. The IBM Lab wants to hear from you, don’t miss this opportunity!

Visit the survey here.

Things are moving on the RFE website. It is now possible to order the RFE’s by ‘New’ (most recently created or ‘Hot’ (that received highest number of votes). The good thing is also that now it is easy to identify RFE’s in the ‘under consideration’ status, meaning the ones that are on the way to be implemented. Check the list using the ‘Hot’ sort and see that RFE’s are analyzed by the DEV team and used to implement new functionality. I will now on include the top 5 RFE’s and their status.

Do not forget to vote for one or several of those RFE’s if they fit your requirements. The more votes, the more chances that the Dev Team will seriously consider the request.
