We’ve started planning our 2014 Informix conference. I hope to announce the date and location in the August Insider. The IIUG board decided to go east. The two cities we are currently looking at are Miami and Washington. Personally I think both locations are great, but until we finalize the contract everything is possible. Please stay tuned and make sure the IIUG conference is in your 2014 budget. Until then, watch the Insider and the IIUG website for events close to you.
If you are interested in more than just Informix, the IBM Information On Demand conference will take place in Las Vegas, November 3-7. Early bird registration will end on September 13.

|Topic:||Discover the power of Recursive SQL and query transformation with IBM Informix 12.1
|Date:||Tuesday, August 27th|
|Time:||8:30 AM Pacific

11:30 AM Eastern
4:30 PM London

|Presented by:||Jerry Keesee – Director, IBM Informix Database Development (IBM)
Ajay Gupte – Software Engineer (IBM)
This presentation will provide an overview of the Recursive SQL with the CONNECT BY clause feature. We will provide examples of typical practical database problems and describe in detail how they can be solved with recursive SQL. The problems discussed include for bill of materials, obtaining the number of employees for each manager in a particular sub-organization, converting linked dimension hierarchies in a star schema to fixed dimension hierarchies, tracking packages, and generating test data. This presentation compares the new solutions with traditional solutions of these problems and discusses the advantages and disadvantages of the various methods. This presentation will also discuss the query transformation techniques with Informix vNext features which will focus on how query blocks are moved between different levels and optimized using examples and diagrams. Users will learn how to analyze complex examples based on various Informix 12.1 features. Examples included in this session are query block movement, table re-ordering, complex ANSI joins, sub-queries, derived tables, views, connect by, OLAP functions, setops cases.

This year, the contest is being held over the web so that anyone, anywhere in the world can participate between July 9 and September 30, 2013. The winner will be the DBA who can get the most transactions per minute in an OLTP benchmark and at the same time run a batch billing job and generate the most bills in a 10 minute run.

One of the most important steps in optimizing and tuning database is to identify the queries that are causing problems. In general, if you take the most inefficient ten queries and optimize them properly, then you will immediately see the result on the overall database performance. Then you can re-iterate the same process and optimize the next ten queries. So, how can you identify the queries which causing problem? One way to go is to find out the queries which running for a long period of time, though it’s not always necessary that longest running means a slow query.
You can use OAT, onstat commands etc. to get this information but the easiest way to run the following SQL against sysmaster:syssqltrace table to identify top ten queries running for long period of time:
SELECT FIRST 10 sql_runtime, sql_statement FROM sysmaster:syssqltrace WHERE sql_runtime > 0 ORDER BY sql_runtime DESC;
Make sure SQLTRACE configuration parameter is enable for SQL tracing. You may include other columns from sysmaster:syssqltrace table in the above SQL to get more detail information about queries.

There is now an Informix group on LinkedIn. The group is called “Informix Supporter”, so anyone loving Informix can join, from current IBM employees, former Informix employees, to users. It will also be a good occasion to get in touch with others or long-time-no-seen friends. If you fancy showing the Informix logo on your profile, join.
