HCL Informix® V14.10 documentation
Welcome to the documentation for HCL Informix® 14.10 and related client tools and products. The current fix pack level of Informix is 14.10.xC13.
Product overview
HCL Informix® is a fast and scalable database server that manages traditional relational, object-relational, and dimensional databases. Its small footprint and self-managing capabilities are suited to embedded data-management solutions.
Installing
These topics describe how to install HCL Informix® database servers, client products, and DataBlade® modules.
Administering
In addition to administering the database server, you can tune performance, replicate data, and archive data.
Migrating and upgrading
You can upgrade to the 14.10 release of HCL Informix® or migrate from other database servers to Informix. 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.

Mapping for field types

The following table shows the mapping supported between the types defined for the ifxtype parameter in the UDTMetaData.setFieldType() method and the Java™ data types as they appear in the Java™ class file. Data types not shown in this table are not supported within the opaque type.


ifxtype parameter type from com.informix.lang.IfxTypes	Java™ data type
IFX_TYPE_BIGINT	long
IFX_TYPE_BIGSERIAL	long
IFX_TYPE_CHAR	java.lang.String
IFX_TYPE_SMALLINT	short
IFX_TYPE_INT	int
IFX_TYPE_FLOAT	double
IFX_TYPE_SMFLOAT	float¹
IFX_TYPE_DECIMAL	java.lang.BigDecimal
IFX_TYPE_SERIAL	int
IFX_TYPE_DATE	Date
IFX_TYPE_MONEY	java.lang.BigDecimal
IFX_TYPE_DATETIME	java.lang.Timestamp if starting qualifier is Year, Month, or Day; otherwise, java.lang.Time (see Field lengths and date-time data).
IFX_TYPE_INTERVAL	com.informix.lang.IfxIntervalYM if starting qualifier is Year or Month; otherwise, com.informix.lang.IfxIntervalDF (see Field lengths and date-time data).
IFX_TYPE_NCHAR	java.lang.String
IFX_TYPE_INT8	long
IFX_TYPE_SERIAL8	long
IFX_TYPE_BOOL	boolean
IFX_TYPE_CLOB	java.sql.Clob
IFX_TYPE_BLOB	java.sql.Blob

¹ This mapping is JDBC compliant. You can map IFX_TYPE_SMFLOAT data type (via the JDBC FLOAT data type) to the Java™ double data type for backward compatibility by setting the IFX_GET_SMFLOAT_AS_FLOAT environment variable to 1.
