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
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:

Progress DataDirect for JDBC for Amazon Redshift (Redshift driver)
The Redshift driver supports the JDBC API for SQL read-write access to the
Redshift database. Also, it supports:
* All JDBC Core functions
* The core SQL-92 grammar
Changes Since 6.0.0 GA
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. If a log file name does not include the
.log extension, the driver automatically appends it.
* 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.
* 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 support proxy server connections.
* The driver has been enhanced to support the following data types:
- Text maps to LONGVARCHAR
- Time maps to TIMESTAMP
- Time with time zone maps to TIMESTAMP
- Timestamp with time zone maps to TIMESTAMP
* 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.
* The driver has been enhanced to support stored procedures for Redshift.
* The driver supports the CallEscapeBehavior connection property. It determines
whether the driver calls a user-defined function or a stored procedure when
JDBC Call escape syntax is used in a SQL statement.
* 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 driver no longer registers the Statement Pool Monitor as a JMX MBean by
default. To register the Statement Pool Monitor and manage statement pooling
with standard JMX API calls, the new RegisterStatementPoolMonitorMBean
connection property must be set to true.
Notes, Known Problems, and Restrictions
The following are notes, known problems, and restrictions with the driver.
Using SSL
---------
When trying to connect to a database using SSL encryption, you may receive an
error message similar to: "PRNG not seeded". This is because certain versions
of some operating systems do not generate truly random numbers necessary for
encryption. For more information about this error and available patches,
please refer to the Web site: http://www.openssl.org/support/faq.html#USER1
Using Bulk Load
---------------
For bulk load users: If the driver throws the error "The specified connection
object is not valid for creation of a bulk load object" while you are
attempting to use the DataDirect Bulk Load API, ensure that redshift.jar is
listed before any other DataDirect drivers on your classpath.
Executing DataDirect Shell Script
---------------------------------
For UNIX 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. Additional information on driver support for the JDBC API can be
found in the "JDBC Support" section of the product USER'S GUIDE.
* The driver allows PreparedStatement.setXXX methods and ResultSet.getXXX
methods on Clob data types, in addition to the functionality described in
the JDBC specification. The supported conversions typically are the same as
those for LONGVARCHAR, except where limited by database support.
* 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 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.
Documentation
PROGRESS DATADIRECT FOR JDBC FOR AMAZON REDSHIFT DOCUMENTATION SET
