Extending Informix®
Beyond standard relational database objects, HCL Informix® can be extended to handle specialized data types, access methods, routines, and other objects. Informix includes many built-in extensions that are fully integrated in the database server. Informix also provides DataBlade® modules, which are packages of extended database objects for a particular purpose and that are installed separately from the database server. Alternatively, you can create your own user-defined objects for Informix.
Creating extensions
You can create user-defined data types, routines, access methods, and other database objects to suit your needs. You can use application programming interfaces to write user-defined routines and applications that access data in Informix® databases.

Create distribution media

To ensure that customers can install DataBlade® modules and other HCL Informix® products by using common instructions, the product you distribute must conform to the HCL Informix® DataBlade® module installation standard. BladePack creates an interactive installation that ensures a consistent user interface.

To distribute multiple products with their own installations on a CD-ROM or tape, rename the cdrom directory to the name of the DataBlade® module before you copy the directory and its contents to the media or into the archive file.

For example, to install the Circle DataBlade® module from CD-ROM, the installer mounts the CD-ROM, changes to the circle subdirectory, and executes the setup program.

Important : Put the Setup.exe program in a short path. Due to a Windows™ limitation, if the path for Setup.exe is too long, it fails to execute.
