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.

Do not forget to vote for one or several of those RFE’s if they fit your requirements.

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 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.

For this issue, I did not have anything special. So I’m just dropped the last query I used today checking where my clobs and blobs are.


select a.tabname, b.colname, c.name
from systables a, syscolumns b, sysxtdtypes c
where a.tabid = b.tabid
and b.extended_id = c.extended_id
and (c.name = "clob" or c.name = "blob")
order by 1,2;
