Highlights: Informix Dynamic Server 11.70.xC4 Early Validation Program Announcement
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.
I wonder sometimes if in the era of social networks and blogs there is still a place for an old fashioned newsletter. I am advertising many blogs in the Insider. I visit them all. By the number of visits and comments not many of you do the same. Please do. There is a great deal of interesting stuff in them.
On one hand I would like to see more blogs, on the other hand it becomes harder to follow. Without a good search capability many great technical articles posted in blogs are not available to you when you actually need them. I am sorry to say the same about the Insider. We have been promised a Web 2.0 site with search capabilities. I have lost my patience and am planning to post all technical articles from the past few years and put them on our site with an Index that will let you find things easily.
Will presence in social networks and blogs help marketing Informix? I have no idea. The beauty of it is you can never tell. In Israel a post on Facebook started a movement that is shaking the country. I joined tonight a 15,000 people march in Jerusalem which was one of several marches across the country. It is encouraging to see young people getting out of the cyberspace and into the real world and making a difference. I doubt many of you are interested in Israeli internal affairs. But I wrote about it just to say that we have the power to change things, so keep up your good work and let's all hope it change things eventually.

FASTEST Informix DBA Training from Lester Knutsen and Art Kagel
As IT professionals, we are constantly asking ourselves how can we do our jobs better? How can we improve the database systems for which we are responsible?
Do you wonder how taking advantage of Informix's Timeseries, Geospacial, and custom designed data types might help your projects soar but don't know how to get started? Have you wondered how to leverage your existing 4GL source code into modern graphical, web based, and mobile applications? Can the Informix Flexible Grid feature improve the security, safety, and performance of your databases? Is there any way to reduce our storage costs? How can we leverage our existing databases and perform complex Decision Support queries without affecting our production applications and without the complexity of setting up and maintaining a separate Data Warehouse?
Advanced Datatools has to expertise to help you evaluate all of the new features in Informix version 11.70 and to make best use of the features and facilities you have available to you. Call us to arrange a free consultation conference with one of our experts. We have the experience to recognize opportunities for improvement that you may have been passing up.

Informix Chat with the Lab
In the 11.70 release, Informix has introduced the ability to install and run as a "Private Server", i.e. without access to user root or user informix. Since running as an unprivileged user makes OS authentication of users impossible, IDS has also introduced the concept of "Mapped Users". This allows creation of users that are not necessarily known to the OS. Note that "Mapped Users" is not restricted to "Private Server".
Watch for the announcement of this upcoming Chat with the Lab at the new Informix Chat with the Lab home page on DeveloperWorks:https://www.ibm.com/developerworks/wikis/display/ifmxchatwithlab/Home New in DeveloperWorks

Reserve memory for prevent out of memory situation
MOut of memory is an undesired state of any database operation where no additional memory can be allocated for use by database. Historically, the out of memory condition is more common in embedded environment, where database server configured to run in low memory configuration. The out of memory situation may lead to database server hung or abnormal outage. Informix introduced a new mechanism to efficiently handle the out of memory situation. It provides more control over the database configuration in low memory condition. Now you can reserve a specific amount of memory to allows Informix to continue with critical database activities even in out of memory situation. Examples of some critical activities are event logging, rollback operation etc.
Use the LOW_MEMORY_RESERVE configuration parameter to reserve a specific amount of memory in kilobytes for use when critical activities are needed and the server has limited free memory. For example:
You can also dynamically adjust the value of the LOW_MEMORY_RESERVE configuration parameter with the onmode -wm or -wf command.
No matter how the LOW_MEMORY_RESERVE configuration parameter is set, the maximum size of reserved memory is 20 percent of the value of the SHMVIRTSIZE configuration parameter. By default, the LOW_MEMORY_RESERVE is set to 0, which means disabled. If the value is less than 128, the following messages are displayed:
Look for the last two lines in the onstat -g seg command to monitor the LOW_MEMORY_RESERVE value. The first of these lines shows the size of reserved memory in bytes. The second of these lines shows the number times that the server has used this memory and the maximum memory needed.
The online.log also displays appropriate messages each time low memory reserve change. For example:
The low memory reserve is one of the many features that introduced in Informix version 11.70.xC3.
