A developerWorks article published today provides a nice summary of IDS replication features. Replication technologies in Informix Dynamic Server by IDS engineers Madison Pruet, Nagaraju Inturi and Nick Geib, takes the reader through Enterprise Replication (ER) and High Availability Clustering, namely Shared Disk (SD) secondary servers, High-Availability Data Replication (HDR), and Remote Standalone (RS) secondary servers.
What I like about this article is that each technology is introduced with a simple example of setting it up, so as a quick start summary it works very well.
One link I would add to the list of resources at the end of the article is the Informix Dynamic Server 11: Extending Availability and Replication RedBook which is an excellent way to follow up and learn more about the topics introduced here.[Read More]

DeveloperWorks, currently celebrating its 8th birthday, has a new blog, and the Informix blogosphere has a new node, in the form of Informix replication architect Madison Pruet's Replication Roundtable. Anyone who has had the pleasure of being on a conference call with Madison will know he's not afraid to express himself. Madison opens his blog with an exposition on the MACH11 Cluster.
If you have any interest in the powerful replication features of IDS, this is one to watch.[Read More]
Firstly, if you follow The Informix Zone you will already know there's a new Informix RedBook, 162 pages of high availability goodness entitled: Informix Dynamic Server V10: Superior Data Replication for Availability and Distribution. This compliments the RedBook published last December: Informix Dynamic Server V10 . . . Extended Functionality for Modern Business.
Secondly, IBM RedBooks are pioneering a new authoring process known as RedWiki. The old style RedBook authoring process took the form of a residency. Authors, typically IBM employees, would travel to a specific site and work there until the job was done. With the new process, anyone can apply to be an author, and the team collaborate on the book via a Wiki page from their regular locations working part-time. I like this concept, it can mean larger teams, and can draw on a greater pool of authoring talent. We use wiki pages extensively within Informix support and development both informally in small teams and in a larger more structured environment.
I turned down the last opportunity for a RedBook residency.. the flesh was willing but the time was lacking. With the Wiki-based authoring process I'd have probably applied. To see an example of the new style of RedWiki take a look at PHP Zend for i5/OS.
I hope this concept catches on and look forward to seeing some Informix RedBooks written this way. Judging by the expertise on display in the IIUG and comp.databases.informix newsgroups there would be no shortage of enthusiasm and talent for a distributed Informix RedBook.
