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 extensionsYou 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.

Repairing R-tree indexes after migrating to a different version of a DataBlade module

About this task

After you migrate to a different version of a DataBlade® module, you must synchronize R-tree index information and operator class functions for every R-tree index that uses the migrated DataBlade module.

To repair R-tree indexes after migrating a DataBlade module:

Procedure

Determine which R-tree indexes are dependent on the migrated DataBlade module.
Run the following command for every affected R-tree index:
```
oncheck -u update_capsules database:table# index
```
Identify each index with its name, the name of the table it is based on, and the name of the database containing that table.
Restart the database server.
