Editorial Back to top

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.

Informix Chat with the Lab

Topic: Discover the power of Recursive SQL and query transformation with IBM Informix 12.1
Date: Tuesday, August 27th
Time: 8:30 AM Pacific
10:30 AM Central
11:30 AM Eastern
4:30 PM London
5:30 PM Paris
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.

New in DeveloperWorks

11 Jul 2013
Starting with IBM Informix 11.70xC2, Informix started supporting the non-root installation feature. This feature, sometimes called private installation, allows Informix to be installed by a user other than root, and permits the software to run without user Informix or group Informix on the machine. Inside the server, Informix will be used as the owner of the system catalog, but neither user Informix nor group Informix will have any special privileges with respect to a private server. The CSDK and other installers which are part of the Informix bundle will also permit non-root users to install the software. This article discusses aspects of this feature in Informix and provides information on how to manage users using JDBC, ESQL/C and ODBC drivers

Identifying Probable Inefficient Queries

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.

Informix blogs and wikis

I am trying something new on this section. I will first mention the blogs and wikis that have been updated during the last month. Blogs and wikis that have not been updated for over 6 months will be removed.

More Blogs and Wikis

Forums, groups, videos, and magazines

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.
