IIUG Insider (Issue #254) September 2021

Highlights: IIUG World 2021 Registration Closes October 4 at Midnight EDT!

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.


This is your last chance to register for IIUG World 2021. Our virtual conference. It is a virtual conference
but it is a great event. We hope to have a regular conference in 2022. I’m well aware that in a virtual conference you don’t meet your friends and colleagues in person. On the other hand, it is much cheaper and has the advantage of attending sessions from your home or office without traveling.

Don’t miss it.

The following sections has the detail and a link for registration.

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.

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