Upgrading is an in-place migration method that uses your existing hardware and operating system software. Some changes to the Informix database server can affect upgrading from a previous release.
Client APIs and tools
You can use the HCL Informix® implementation of client APIs to develop applications for Informix database servers.
Embedding Informix®
When you embed HCL Informix®, you can use enterprise-class high-availability and high performance with embeddability features such as easy programmability, a small disk and memory footprint, and silent deployment.
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.
Data warehousing
In addition to designing and implementing Informix® dimensional databases, you can use tools to create data warehouse applications and optimize your data warehouse queries.
Designing databases
The first step in creating a relational database is to construct a data model, which is a precise, complete definition of the data you want to store. After you prepare your data model, you must implement it as a database and tables. To implement your data model, you first select a data type for each column and then you create a database and tables and populate the tables with data. You can also implement fragmentation strategies and control access to your data.
JSON compatibility
You can use the popular JSON-oriented query language created by MongoDB to interact with data stored in HCL Informix®.
Security
You can secure your Informix® database server and the data that is stored in your Informix databases. You can encrypt data, secure connections, control user privileges and access, and audit data security.
SQL programming
You can use the HCL Informix® implementation of the SQL language to develop applications for Informix database servers.
Troubleshooting HCL Informix®
Several troubleshooting techniques, tools, and resources are available for resolving problems that you encounter in your HCL Informix® database server environment.

The onpladm utility features

You can create and maintain the onpload database with the onpladm utility and the ipload utility. The onpload database stores information about the High-Performance Loader (HPL) objects of load and unload jobs.

The first time that you issue a create command, the onpladm utility creates the onpload database, if it does not yet exist.

The onpladm utility can perform the functions that the following table describes.


Object	Operation
Project	Create, delete, describe, list, run
Job	Create, delete, describe, list, modify, run
Map	Create, delete, describe, list, modify
Format	Create, delete, describe, list, modify
Query	Create, delete, describe, list, modify
Device array	Create, delete, describe, list, modify
Computer	Create, delete, describe, list, modify
Target server	Configure and list default settings
Filter	Create, delete, describe, list, modify

The onpladm utility also allows you to:

Create jobs and other objects with a single, minimum-input command.
Specify object characteristics in specification files.
Create, load, or unload jobs for all tables in a database.
Create jobs for an entire database and group the jobs into a project with a single command.
Run individual jobs or projects independently.

Important: The most effective way to use onpladm is to create and modify HPL objects is to:

Create the default objects by using default job creation options.
Use describe object syntax to describe the objects.
Manually modify these objects with correct values for different configuration parameters.
Use modify object syntax to correctly create these objects.
