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.
