Before You Begin

You can create an R-tree index on a table after you complete the following tasks:

1. Install a DataBlade module on your database server that includes the following objects:
   • A user-defined data type that can be indexed with an R-tree index
   • An operator class that specifies the functions to be used with the R-tree index
   • The support and strategy functions required by the operator class

   Examples of DataBlade modules that use the R-tree access method are the IBM Informix Geodetic DataBlade module and the IBM Informix Video Foundation DataBlade module.

   For more information on these modules, refer to IBM Informix DataBlade Modules That Use the R-Tree Access Method.

2. Create a database.
3. Register the IBM Informix R-Tree Secondary Access Method DataBlade module into your database using BladeManager.

   If the DataBlade module described in step 1 defines a dependency on the IBM Informix R-Tree Secondary Access Method DataBlade module, you can skip this step, because BladeManager automatically prompts you to register the IBM Informix R-Tree Secondary Access Method DataBlade module when you register the DataBlade module described in step 1.

   For more information on the IBM Informix R-Tree Secondary Access Method DataBlade module, refer to R-Tree Secondary Access Method DataBlade Module.

4. Register the DataBlade module described in step 1 into your database using BladeManager.
5. Create a table that contains one or more columns of the user-defined data type that can be indexed with the R-tree access method.

For information on how to install and register DataBlade modules, refer to the IBM Informix: DataBlade Module Installation and Registration Guide and to the release notes of your DataBlade module.
