IBM seems to have "silently" published a new eBook covering the flexible cluster configuration options of Informix.

The eBook can be found here:

However if you prefer to download the eBook without those tedious and needless registration forms, please try this URL:

ftp://public.dhe.ibm.com/common/ssi/ecm/en/imm14068usen/IMM14068USEN.PDF

However I can't find the eBook on the official IBM website nor on the Discover the New Face of Informix website. Probably it may take IBM a few months to update their websites with the new content :-)

Anyway, the eBook could be useful to spread the word about the excellent cluster and replication technology of Informix that doesn't require expensive hardware components to build highly available database clusters and is not limited to certain hardware platforms/vendors like other database products.
