Create registration scripts for dependent DataBlade modules

All R-tree error messages are contained in the R-tree secondary access method extension.

The R-tree secondary access method extension is automatically registered when needed unless you chose not to install database extensions when you installed the Informix® database server software.

When you develop a DataBlade® module that uses the R-tree secondary access method, you can create a dependency on the R-tree secondary access method extension so that BladeManager automatically registers both the extension and the DataBlade module in the correct order. BladeManager is the Informix product you use to register DataBlade modules in a database.

The dependency is signaled by importing an interface object provided by the R-tree secondary access method extension. During registration of the dependent DataBlade module, BladeManager checks interface dependencies and warns the user registering the DataBlade module if the R-tree secondary access method extension is not already registered in the database.
