Post-GA Product Announcements
The readme files will no longer be updated with product announcements and new
features after the General Availability (GA) of the product. For the latest
updates and enhancements, please refer to the release notes
(https://www.progress.com/datadirect-connectors/whats-new).
Requirements
* A supported Java Virtual Machine (JVM) must be defined on your system path.
* The installer program requires a JVM that is Java SE 11 or higher, including
Oracle JDK, OpenJDK, and IBM SDK (Java) distributions.
* The driver requires a JVM that is Java SE 8 or higher, including Oracle JDK,
OpenJDK, and IBM SDK (Java) distributions.
Installation Directory
The default installation directory for the driver is:
* Windows:
C:\Program Files\Progress\DataDirect\JDBC
* UNIX/Linux:
/opt/Progress/DataDirect/JDBC
Note: For UNIX/Linux, if you do not have access to "/opt", your user's home
directory will take the place of this directory.
Data Source and Platform Support
For the latest data source and platform support information, refer to the
Product Compatibility Guide:
https://docs.progress.com/bundle/datadirect-product-compatibility/resource/
datadirect-product-compatibility.pdf
Changes Since 6.0.0 GA
Enhancements
------------
* The driver has been enhanced to comply with FIPS standards for data
encryption. As part of this enhancement, the driver was tested with
FIPS 140-3 enabled using a Red Hat OpenJDK 21 on a Red Hat Universal Base
Image 9 instance.
Changed Behavior
----------------
* The connection property SpyAttributes has been updated to exclude the
attribute load=classname, which was previously used to load the driver
specified by the given class name. See SpyAttributes for details.
* The installer program now requires you to install a JRE that is Java SE 11 or
higher before running the installer. In earlier versions, the JRE used by the
installer program was included in the product. However, to avoid potential
security vulnerabilities, the installer program no longer includes a JRE.
Instead, the installer program uses the JRE in your environment to allow for
the most secure version of a JRE to be used.
Note: This change does not affect the JVM requirements for the driver. For the latest
driver requirements, refer to the Product Compatibility Guide:
https://docs.progress.com/bundle/datadirect-product-compatibility/resource/
datadirect-product-compatibility.pdf
Release 6.0.0 Features
Enhancements
------------
* The driver has been enhanced to include timestamp in the Spy and JDBC packet
logs by default. If required, you can disable the timestamp logging by
specifying the following at connection: For Spy logs, set
spyAttributes=(log=(file)Spy.log;timestamp=no) and for JDBC packet logs,
set ddtdbg.ProtocolTraceShowTime=false.
* Interactive SQL for JDBC (JDBCISQL) is now installed with the product.
JDBCISQL is a command-line interface that supports connecting your driver to
a data source, executing SQL statements and retrieving results in a terminal.
This tool provides a method to quickly test your drivers in an environment
that does not support GUIs.
* The RegisterStatementPoolMonitorMBean connection property has been added.
Note that the driver no longer registers the Statement Pool Monitor as a
JMX MBean by default. You must set RegisterStatementPoolMonitorMBean to true
to register the Statement Pool Monitor and manage statement pooling with
standard JMX API calls.
Changed Behavior
----------------
* Java SE 7 has reached the end of its product life cycle and will no longer
receive generally available security updates. As a result, the drivers will no
longer support JVMs that are version Java SE 7 or earlier. Support for
distributed versions of Java SE 7 and earlier will also end, including
IBM SDK (Java Edition).
* If you attempt to execute a DatabaseMetadata API with catalogName filter set
as '' (Empty String) against Informix 14.1, the API will return the full list
of objects instead of an empty result. All DatabaseMetadata APIs, such as
getTables() and getColumns(), which support catalogName as filter are affected
by this behavior.
Notes, Known Problems, and Restrictions
The following are notes, known problems, and restrictions with release 6.0.0 of
the driver.
Executing DataDirect Shell Script
---------------------------------
For UNIX/Linux users: If you receive an error message when executing any
DataDirect for JDBC shell script, make sure that the file has EXECUTE
permission. To do this, use the chmod command. For example, to grant EXECUTE
permission to the testforjdbc.sh file, change to the directory containing
testforjdbc.sh and enter:
chmod +x testforjdbc.sh
JDBC Methods
------------
The following notes on JDBC methods apply generally to Progress DataDirect for
JDBC drivers.
* The driver allows PreparedStatement.setXXX methods and ResultSet.getXXX
methods on Blob/Clob data types, in addition to the functionality described in
the JDBC specification. The supported conversions typically are the same as
those for LONGVARBINARY/LONGVARCHAR, except where limited by database support.
* Calling CallableStatement.registerOutputParameter(parameterIndex, sqlType)
with sqlType Types.NUMERIC or Types.DECIMAL sets the scale of the output
parameter to zero (0). According to the JDBC specification, calling
CallableStatement.registerOutputParameter(parameterIndex, sqlType, scale) is
the recommended method for registering NUMERIC or DECIMAL output parameters.
* When attempting to create an updatable, scroll-sensitive result set for a
query that contains an expression as one of the columns, the driver cannot
satisfy the scroll-sensitive request. The driver downgrades the type of the
result returned to scroll-insensitive.
* The driver supports retrieval of output parameters from a stored procedure
before all result sets and/or update counts have been completely processed.
When CallableStatement.getXXX is called, result sets and update counts that
have not yet been processed by the application are discarded to make the
output parameter data available. Warnings are generated when results are
discarded.
* The preferred method for executing a stored procedure that generates result
sets and update counts is using CallableStatement.execute(). If multiple
results are generated using executeUpdate, the first update count is returned.
Any result sets prior to the first update count are discarded. If multiple
results are generated using executeQuery, the first result set is returned.
Any update counts prior to the first result set are discarded. Warnings are
generated when result sets or update counts are discarded.
* The ResultSet methods getTimestamp(), getDate(), and getTime() return
references to mutable objects. If the object reference returned from any of
these methods is modified, re-fetching the column using the same method
returns the modified value. The value is only modified in memory; the database
value is not modified.
