IIUG Insider (Issue #269) December 2022

Highlights: Short Note from the President

Welcome to the International Informix Users Group (IIUG) Insider! Designed for IIUG members and Informix user group leaders, this publication contains timely and relevant information for the IBM Informix community.


My first new year editorial was in December 2005. I wrote it in English, Spanish, French, Portuguese and German. I kept doing it until 2010. Since then, It seems there is no point.

2022 was OK. Informix is still alive and kicking. IBM and HCL are keeping the product going.

The IIUG is struggling to serve the user community. We did not have a conference in 2022.

We are hoping to have one in 2023. However, our YouTube channel created in 2021 has 89 videos, 66 have been added in 2022 and has nearly 8,000 views. More than all our conferences combined.

We do know what happened with Informix in 2022. So, let’s hope it will be even better in 2023.

The IIUG Board is wishing the IIUG community a happy New Year.

Short Note from the President

Hello IIUG Members,

Happy New Year and many blessings to all of you in 2023!

2022 was a good year for Informix and the IIUG. However, we didn’t accomplish everything we sought out to do.

We wanted to do an in-person event, since we haven’t had one in three years. Unfortunately, a number of circumstances got in the way of us fulfilling that mission.

This year we will do our best to hold an IIUG event either in person or virtual.

On a more positive note, thanks to Lester Knutsen, we were able to execute Monthly IIUG Tech Talks. These are available for replay on the IIUG YouTube channel. We hope to continue with this same format this year, with the first Tech talk coming up in February.

Lastly, I would like to personally thank Ognjen Orel and Lester Knutsen for their years of service on the IIUG Board of Directors. Both will be terribly missed. I would also like to welcome Tom Beebe and Henri Cujass as new board members for this term. We are looking forward to working with them.

Obtain the query plan of a running query

Many times a DBA is called to check upon a slow process. Most of the times those processes are running a slow query.

Sometimes it’s hard to know if the query is using the best query plan or not. A DBA can reproduce the query, but it it was prepared without values or if the statistics were changed after it started there is no guarantee that the query plan seen by the DBA is the same as the running query.

We have “onstat -g pqs” which sometimes can give us a clue, but it’s mostly cryptic and undocumented. If a user has X-Windows he can try xtree, but it’s a bit strange for todays standards.

We also have SQLTRACE, but if it was not set when the query was launched it will not capture the info (and besides, due to the circular nature of the buffer it may not be there at the time we need it).

A simple pseudo-table in sysmaster could probably implement this with ease.

It could also be extended to support the “last” query plan making it easy to get the query plan in any tool

Informix should be able to change owner on tables and any other objects

If user=informix creates all database and all tables, then programmer creates table but user=informix cannot change it. Only drop it.

Backup Individual database, not entire instance

Need a mechanism, similar to ontape, to backup a live database (as opposed to entire instance), without locking it.
