What's new in HCL Informix JDBC Driver, Version 4.10
This publication includes information about new features and changes in existing functionality.
| Overview | Reference |
|---|---|
Detached Smart Triggers Smart Triggers are enhanced to support Detached triggers when used with a 12.10.xC10 or newer Informix server. Detached triggers allow reconnecting and detainment of messages if you are disconnected. |
Detach trigger |
Enable java.util.logging in JDBC You can now use the JDBC standard java.util.logging to debug and trace the JDBC driver. Driver.getParentLogger() now returns a proper top level logger for the Informix JDBC driver. |
Debug your JDBC API program |
Expanded Connection API’s As part of the JDBC 4.1 specification, the Informix JDBC driver now supports new API’s on the java.sql.Connection interface. The API’s abort(), setNetworkTimeout(), getNetworkTimeout() are now supported. |
Classes implemented in Informix JDBC Driver |
Expanded Statement API’s As part of the JDBC 4.1 specification, the Informix JDBC driver now supports new API’s on the java.sql.Statement interface. The API’s closeOnCompletion() and isCloseOnCompletion() are now supported |

setObject() now accepts java.util.Calendar and java.math.BigInteger As part of the JDBC 4.1 specification, the Informix JDBC driver PreparedStatement and CallablePreparedStatement objects for Informix JDBC now support passing in java.util.Calendar and java.math.BigInteger objects into the setObject(..) API’s |

Add JDBC escape syntax for limit rows returned Adds JDBC standard escape syntax for limiting returned rows. For more information see, JDBC 4.1 specification section 13.4.6. Example: “SELECT * FROM TABLE1 WHERE F1 > 100 {limit 20 offset 10}” |
The escape syntax |

|---|---|
CLIENT_LABEL connection variable You can set CLIENT_LABEL in your JDBC connection URL and track this label using `onstat -g env <sid>` or by querying the table `sysmaster:syssesenv` |
Informix environment variables with the HCL Informix JDBC Driver |
setObject() accepts java.util.Date PreparedStatement and CallablePreparedStatement objects for Informix JDBC now support passing in java.util.Date (in addition to already supporting java.sql.Date) as input to any setObject(…) API call. |

| JDBC 4.0 compliance The HCL Informix JDBC Driver is now compliant with the Java™ Database Connectivity (JDBC) 4.0 specification. |
Classes implemented in Informix JDBC Driver |
| Query smart large objects with read-only access You can now specify that smart large objects are queried with read-only access in JDBC connections. By default, smart large objects are queried with read-write access. To set read-only access for smart large objects, include the IFX_LO_READONLY=1 environment variable in the JDBC connection string. |
Informix environment variables with the HCL Informix JDBC Driver |
| Overview | Reference |
|---|---|
| Keep JDBC socket connections open You can now keep long-running JDBC socket connections from timing out due to inactivity. Set the IFX_SOC_KEEPALIVE environment variable to true when you open a socket connection with the Informix JDBC Driver. |
Informix environment variables with the HCL Informix JDBC Driver |
| Reoptimize JDBC queries When you run queries through the Informix JDBC Driver, you can now reoptimize previously prepared query plans. Set the new withReoptimization argument of the IfmxPreparedStatement.executeQuery method to true. |
Reoptimize queries |

|---|---|
| Support for Java 7 HCL Informix 12.10.xC5 software supports Java Platform Standard Edition (Java SE), Version 7. Informix installation applications install IBM® Runtime Environment, Java Technology Edition, Version 7 on most platforms by default. That version is used to run Java user-defined routines that are created in the server. Check the machine notes for your operating system platform to determine whether the installation application requires a preinstalled JRE. |
Java technology dependencies |
| New locale for the JDBC Driver The Informix JDBC Driver now supports the Estonian and Lithuanian locale, et_ee. |
