Editorial Back to top

I am often asked why I send our IT employees to Informix conferences. My IT department’s budget for education is not large. Adding the air fare and hotel to the conference price, one conference attendee carries a lot of weight. But I send at least one of my IT team every year because I know it is worth it. No where else will they be exposed to such a range of topics. Let us look at one example. You can attend a course on Java, but a course is limited to a single viewing. At the Vienna conference you can broaden your knowledge by looking at it from the pure Java point of view, and also the JDBC driver, JSP, Java in the server and the web datablade points of view. You can learn about migrating your 4GL programs and tuning your applications. Even unrelated topics, like new features in IDS 10, can tell you about a feature that can help you in your application programming. There is no course that can compete with that.

But education is not the whole story. Where else can you meet people like Jonathan Leffler, John Miller and Guy Bowerman who are actually developing the product, or users like Darryl Priest, Sergio Ferreira and Hal Maner who are facing the same challenges you are. Where else can you meet your colleagues from all over Europe and establish new relationships and partnerships.

Try it — you will not regret it.

When you are at the conference look for the IIUG board members. We are there for you. If you have a question, a request or a wish, come to us — we will do our best. It is important for us to meet you and feel the pulse of the Informix user community.

See you in Vienna!

Vnext Survey Results

We would like to thank everyone who filled out our recent survey on the top features you would like to see in the future releases of Informix. There were 254 responses, and of that 114 were by DBAs, the rest were various other IT related jobs.

There were definitely a few surprises in the results. There were 32 features that had been collected over the last couple of years that were used in the survey. One feature was collected the day before the survey, and it caused some discussion on the Informix-forum as to whether it was relevant to Informix or not. That was the request to give Informix native support for XML. As the survey shows, this ranked number 10 in importance to the Informix community! The number one item was to add an automatic update statistics to the engine. Rumor has it that this is already being worked on, but I’m sure at the Information On Demand (IOD) conference we will hear more about the features included in the next version.

In addition to ranking the top 10 requests of the features already identified, we also got a huge response in the write in section to list more features wanted. The updated feature request list (vNext Requests) can be found on http://www.iiug.org on the left side. Select the drop down labeled “IIUG.org Hot Spots”. If you would like to request an additional feature to be added to the list, send an email to us at webcontent@iiug.org.

SEIUG and IBM Sponsor 4GL-to-EGL Workshop in Atlanta, September 27th

Southeast Informix Users Group and IBM are teaming up to offer a free one day Application Development workshop on Wednesday, September 27, 2006, in Atlanta.

This workshop will demonstrate how, without writing any Java or HTML, an Informix 4GL (i4GL) developer can re-use existing business logic in Web applications. Without any knowledge of the underlying technologies of Web Services, an i4GL developer can expose business logic as a Web Service.

All this can be accomplished by migrating the business logic to Enterprise Generation Language (EGL) and using the features of EGL to develop the Web applications and services.

IBM will also provide a preview of work of being done to migrate 4GL applications to an EGL based GUI application. This workshop’s target audience is application developers and will offer hands on tutorials.

Topics will include:

  • High level overview of the EGL language
  • Migrate a sample 4GL application to EGL
  • Develop Web applications using migrated business logic
  • Expose migrated business logic as a Web Service
  • GUI direction

The workshop will be held at the IBM Technical Exploration Center in Atlanta in a computer lab setting. This information packed event will start promptly at 8:00 AM and run until 5:00 PM. Lunch will be provided.


Technical Exploration Center – Atlanta
4111 Northside Parkway
Atlanta, Georgia 30327


This event is free, but registration is required as space is limited.

Perform point-in-time table-level restore in Informix Dynamic Server
This article describes how to perform point-in-time table-level restores that extract tables or portions of tables from archives and logical logs. Table-level restore is a new feature for IBM Informix Dynamic Server Version 10.0. This feature is useful where portions of a database, a table, a portion of a table, or a set of tables need to be recovered and also useful in situations where tables need to be moved across server versions or platforms.

Explore the differences between Oracle and IDS functionality, syntax, and much more. This in-depth guide covers the essentials for preparing to port your applications from Oracle to Informix. In addition to DDL, DML, and overall SQL syntax, you’ll learn the differences between Oracle and Informix with regards to the use of large objects, user defined types, user defined routines, and table table partitioning. The author explains what needs to be changed to make an application running on an Oracle database run on an Informix database, and gives alternatives.
developerWorks blogs

The Informix zone at http://www-128.ibm.com/developerworks/db2/zones/informix/ is a great source for technical articles. In addition to that you can enjoy Guy Bowerman’s blog Informix Application Development at:


Guy Bowerman is a senior software engineer in IBM’s Resolution Team, providing advanced technical support, product development, training and bug fixing for Informix products. Guy has worked for Informix Software since 1994 in the UK and US. This blog covers Informix Dynamic Server (IDS) application development, occasionally digressing into IDS on Windows and Linux, security and other random topics.

The following note posted August 2, 2006 is a fine example:

The rise of Informix

The Q2 numbers are in and Informix Dynamic Server experienced another large increase in revenue to build on the growth of Q1. As usual the details are not released publicly but I am officially allowed to say, and I quote.. IDS license revenue grew by double digits in the first half of 2006

Using Websphere connection pooling in a database without transactions

Java 2 EE Connection Pooling

In Java 2 Enterprise Edition it is normal to access the databases using the connection pooling mechanism included on the application server.

The connection pooling mechanism is used following the steps:

  • Define a datasource: This is made on the administrative console of the application server.
  • In the java program ask JNDI (the J2EE directory service) to make a connection:

String JNDI = "java:comp/env/jdbc/testeDBRef";
Context ctx = new InitialContext();
DataSource ds = (DataSource) ctx.lookup(JNDI);
Connection conn = ds.getConnection();
  • In the deployment descriptor refer to the resource used (called in the program)
  • Associate the resource mentioned on the deployment descriptor to the JNDI name of the datasource (configured on the application server).

This works very well. You simply don’t have to worry about managing the amount of connections used in the program, you may leave that task to the application server. With connection pooling you can also reuse the connections that are not needed by creating and destroying connections to the database.

Informix Database without transactions

An Informix database can be created without transaction support. This feature is not normal on a day to day basis, but sometimes there is a customer where this situation happens. When you need to access to a transactionless database with web sphere you get an SQL exception with the following message: No Transaction Isolation on non-logging db’sDSRA0010E: SQL State = IX000, Error Code = -79.746 .

Solution : Inform relational resource adapter to not use transactions

You can, of course, change your database to use transactions, but for my customers that was not an option. In this case you need to create your own data store helper class with some specific functionality to enable the access to such database.

A data store helper is a class used to provide some of your specific behavior to the relational resource adapter (the connection mechanism to databases in web sphere). This class must implement the interface DataStoreHelper. Web sphere comes with helper classes for each database engine (for informix it comes with InformixDataStoreHelper).

To fix the problem we need to define a new DataStoreHelper that extends the behavior of the Informix helper class and rewrite the getIsolationLevel() method to return 0, that means TRANSACTION_NONE.

Then you just need to install it in the classes directory of the application server and use it when defining the data source.


  • Create the helper class
  • Compile the helper class
  • Install the helper classes directory
  • Create your data source but tell it that you use InformixDataStoreHelperNonLoggingMode class
  • Deploy and execute the application

Create the Helper class

Go to your favorite editor and paste the following code:

import java.sql.SQLException;
import java.util.Properties;
import com.ibm.websphere.rsadapter.InformixDataStoreHelper;
* Helper class for trying to use Informix database engine without
* transactions.
public class InformixDataStoreHelperNonLoggingMode
   extends InformixDataStoreHelper {
  public InformixDataStoreHelperNonLoggingMode(Properties props)
* Rewrite the getIsolation level in order to just return
* @param aIntent - Whatever
* @return The isolation level
public int getIsolationLevel(
  com.ibm.websphere.appprofile.accessintent.AccessIntent aIntent)
  throws javax.resource.ResourceException
  return 0;

Use your new helper class

When creating your data source you need to fill the box as shown in the following image:

V10 DBspace changes

Tblspace tblspace

A table or index tblspace (partition) is the space occupied by the table or detached index fragment within a dbspace. The tblspace tblspace is a special system table that tracks the tables within a dbspace. Every dbspace has its own tblspace tblspace that tracks the table and index partitions within its own dbspace. Within the tblspace tblspace, one page is allocated for each partition tracked. On the page there are pointers to each of the extents in the partition. There is only enough space on the page for about 220 pointers on a 2kb page or 440 pointers on a 4kb page, limiting the number of extents allowed within a partition.

There is only one tblspace tblspace per dbspace. However, as with any table it can have multiple extents.

The default first and next extent sizes for the rootdbs are 250 pages and 50 pages respectively.

The default first and next extent sizes for any other dbspace are 50 pages and 50 pages.

Display the tblspace tblspace extent sizes using oncheck -pe or using a sysmaster query:

select * from sysmaster:sysextents where tabname=’TBLSpace’

Potential Problem: Cannot drop chunk

A chunk cannot be dropped if the chunk contains any extents, including the tblspace tblspace extents. When the tblspace tblspace has multiple extents it may prevent dropping a chunk, such as in the following situation:

  • Customer adds a chunk temporarily to a dbspace to create a large table in the dbspace.
  • During processing the tblspace tblspace extends into the newly added chunk.
  • The customer drops the large table and now wants to drop the chunk.

To solve such a problem, the following solutions are available:

  • Drop dbspace. This causes the customer to have to unload the entire dbspace and drop all tables in the dbspace, then drop and recreate the dbspace. This means downtime.
  • Dial-in to drop chunk. Another possible solution is to have Advanced Support dial in and drop the chunk. They would also have to clean up the tblspace tblspace. This caused down time and is risky (usually avoided).

Specify Tblspace Tblspace Extent Sizes

Tblspace tblspace extent sizes can now be specified. This feature can be used to reduce the additional extents being allocated to the tblspace tblspaces, minimising the risk of tblspace tblspace extents being allocated in chunks other than the first chunk. Once a dbspace has been created, the tblspace tblspace first and next extent sizes cannot be altered.

This feature will NOT prevent the reversion of any dbspaces. It will now be possible to revert back to a version prior to this feature, and now have extents for a tblspace tblspace that are not a default value or a doubling of that. The next extent sizes will be adjusted accordingly on the reversion process.

First/Next Extent Sizes – Root dbspace

Root dbspace tblspace tblspace extent sizes specified at instance creation

  • TBLTBLFIRST: This onconfig parameter is used to specify the size of the first extent of the tblspace tblspace for the root dbspace.
  • TBLTBLNEXT : This onconfig parameter is used to specify the next extent size of the tblspace tblspace for the root dbspace. If these parameters are not present, the default sizes are used. Sizes are in kilobytes and must be a multiple of the page size.

First/Next Extent Sizes – non root

Non-Root dbspace tblspace tblspace extent sizes specified at dbspace creation

When creating a new dbspace with onspaces can now specify the first and next extent sizes for the tblspace tblspace

-ef <first extent size>
-en <next extent size>

If these options are not used the default sizes are used sizes are in kilobytes and must be a multiple of the page size


onspaces -c -d dbs1 -p /cooked/chunk1 -o 0 -s 10000 -ef 100 -en 100

Renaming Dbspaces

Dbspaces can now be renamed. The rename dbspace operation only changes the dbspace name, it does not reorganize data. Can be performed by informix user or user with DBA priviliges.

Note: The feature was first introduced in IDS 9.40.UC3 with additional limitations:

  • Cannot rename blobspaces, sbspaces, temporary or external spaces.
  • Cannot rename dbspaces that are referred to by the following configuration parameters:
  • Cannot rename dbspaces if you are using High-Availability Data Replication or if Enterprise Replication is active.

After renaming any space (except extspaces or temporary spaces), perform a level-0 archive of the renamed space and the root dbspace. This will ensure that you can restore the spaces to a state including or following the rename dbspace operation. It is also necessary prior to performing any other type of archive.

A rename done on a HDR primary will propagate to the secondary.

The rename dbspace command updates the dbspace name in all places where that name is stored. This includes reserved pages on disk, system catalogs, the ONCONFIG configuration file and in-memory data structures.

Note: If you rename a dbspace, you must rewrite and recompile any stored procedure code that references the old dbspace name. For example, if you have a stored procedure that contains the ALTER FRAGMENT keywords and a reference to the dbspace name, you must rewrite and recompile that stored procedure.

If you rename dbspaces that are specified in the DATASKIP configuration parameter, you must manually update the DATASKIP configuration parameter after renaming the dbspace.

This is the first time that such a survey has been carried out and it is expected that the results will clearly demonstrate why Informix must be the database of choice for all organizations running mission critical applications.

The survey will investigate the real-time performance of three key aspects of database functionality – hardware efficiency, reliability and scalability.

To share your experiences and, by doing so, be entered into a drawing to win an all-expenses paid trip to the forthcoming IDUG conference in Vienna (2nd to 6th October 2006), visit http://www.oninit.com/survey.

Informix – The Mission Critical Database

Duncan Crabbe, General Manager, OpenPSL said “We are thrilled to be supporting Oninit with this initiative and we see the survey as key to raising general awareness of Informix as the database of choice. We believe that the results of this survey will provide compelling evidence that Informix is, undoubtedly, one of the most reliable and stable databases available on the market today.”
