Editorial

Not much is happening with Informix since the HCL deal. I guess HCL needs time to get things going. Or, maybe it is just this time of year. For me things are very slow as well. So who am I to complain?

Hope for exciting stuff in the July issue.

IIUG President’s Update

I wrote a letter that was published in last month’s IIUG Insider regarding the IBM and HCL Partnership. I hope you all had a chance to read it. In case you missed it, it is available at www.iiug.org/prezletter. I recommend you download the PDF that best fits your language of choice to see what this partnership means for Informix. In case you have any questions, drop me an email at www.iiug.org/president.

Also, it definitely looks like IIUG 2018 will be held in the October 2018 timeframe. A long time ago, when we started this process, I said it cannot be that hard to select a city. Well yes it is. You have to find dates that are available in a city that you can afford and in a hotel that has the correct number of meeting rooms available. We are down to our final list of hotels and the IIUG Board will be voting soon. We hope to have a final decision in time to make an announcement in next month’s IIUG Insider.

Finally, a lot of people have dropped me an email asking me how they can get a copy of the IIUG 2017 sessions. So, here is the secret link: www.iiug2017.org/sessions.zip. If you want a copy of the wonderful Conference guide you can find it at www.iiug2017.org/guide.pdf.

RFE corner

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, is 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 your 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 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, taking into consideration the general interest.

Take some time to examine the full list and vote for the enhancements you would like to see implemented.

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 way 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.

The system catalog has all information about table columns. However it is not readable to non DBAs.

This is a view that does the work. Because the information in sysdefaults is a little cryptic I had to supply a stored procedure to parse it.

create function get_def_val(t_def char(256))

returning varchar(255)

define ret_def varchar(255);

define j, k smallint;

define c char(1);

let k = length(t_def);

if k = 0 then

return "";

end if

if substr(t_def, 1, 1) = " " then

return " ";

end if

let c = substr(t_def, k, 1);

if c is null then

if k = 1 then

return "";

end if

let ret_def = substr(t_def, 1, k - 1);

return ret_def;

end if

for j = 1 to k

if substr(t_def, j, 1) = " " then

exit for;

end if

end for

if j > k then

let ret_def = t_def;

else

let ret_def = substr(t_def, j + 1, k - j);

end if

return ret_def;

end function;

create function get_col_def(t_name nvarchar(128), c_name nvarchar(128))

returning varchar(255)

define ret_def, c_def varchar(255);

define c_type char(1);

select a.default, a.type

into c_def, c_type

from sysdefaults a, syscolumns b, systables c

where c.tabname = t_name

and b.tabid = c.tabid

and b.colname = c_name

and a.colno = b.colno

and a.tabid = b.tabid;

if dbinfo("sqlca.sqlerrd2") = 0 then

return null;

end if

Informix Tech Day on tour in Europe

June was rich in terms of Informix events in Western Europe. Brussels, Belgium hosted 2 Informix related events on June 13th. The morning session was dedicated to the following subject, “Creating real world sensor-to-business-value IoT applications”.

Under this general theme, 3 main topics were presented and discussed:

  • What can IoT bring to companies in terms of Business Value
  • The IBM IoT architecture components from Edge to the Cloud
  • The diversified analytics from the Edge to the Data Centre

The audience was mainly composed of non-Informix Users who have been discovering a new or almost new name for themselves: Informix. Many of them were amazed by how Informix could address IoT and they left the room with a totally different idea of Informix, in any case, very positive feedback.

After attending the morning presentations, some people remained curious about Informix and decided to stay for the afternoon sessions exclusively dedicated to Informix.

Although not initially intended, this local user group meeting turned into a mini-CAC meeting, since several of the most important European Business Partners were attending.

Many important messages were given during this meeting:

  • Presentation of the new IBM-HCL agreement to the local user base
  • Presentation of the Informix Roadmap and where Informix will go
  • Update on Informix new functionality since Informix 11.70
  • Presentation of major Informix functionality rarely used by customers, i.e. encryption, security, replication and Hybrid development

During the session, interesting questions and discussions took place between users, BPs and the HCL team, which hopefully helped the audience to understand this major and exciting change in Informix’ life. Thanks to Hans Miseur and Infocura for the great job organizing this event!

Two day after, the Informix Tech Day moved to Paris with the same presentations schedule and format.

This time the audience was more familiar and there were many more attendees. We understood they were eager to know about this important news about Informix.

Marcelo Cabane, who the audience really appreciated because his introduction was in French, did a great job explaining the agreement and where Informix wants to go now that it is driven jointly by IBM and HCL. The discussions at the end of the meeting showed a globally positive feeling by the customers and partners, who seem to particularly appreciate the energy that HCL and IBM are finally putting into the expansion of Informix in the market place. Many thanks to Stuart Litel and Cindy Lichtenauer who help to set up this event.
