Java SE 5 or higher must be installed and the JVM must be defined on your system

     Installation Directory

The default installation directory for the driver is:

* Windows:
  C:\Program Files\Progress\DataDirect\JDBC_51

* UNIX/Linux:
  Note: For UNIX/Linux, if you do not have access to "/opt", your user's
  directory will take the place of this directory.

     Changes since Service Pack 4

Statement Pooling
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. See "Notes, Known Problems, and Restrictions" for

     Changes for Service Pack 4

BatchMechanism Connection Property
The BatchMechanism connection property has been added to the driver. By setting
BatchMechanism to MultiRowInsert, you enable the driver to use a parameterized
multi-row insert statement to execute batch inserts. MultiRowInsert is the
default setting and provides substantial performance gains when performing batch

CryptoProtocolVersion Connection Property
To avoid vulnerabilities associated with SSLv3 and SSLv2, including the POODLE
vulnerability, CryptoProtocolVersion can be used with the driver.

Result Set Holdability
Support for result set holdability has been added to the driver.


The driver supports standard SQL query language to select, insert, update and
delete data from Amazon Redshift data warehouses. By using DataDirect's Wire
Protocol technology, the driver eliminates the need for client libraries,
improving response time and throughput. In addition, the driver supports a set
of advanced features that includes DataDirect Connection Pooling, data
encryption, and connection failover.
* The driver supports the Amazon Redshift API, version 2012-12-01 and later.

* The driver supports JDBC Core functionality. 

* The driver supports the core SQL-92 grammar.

* The driver supports DataDirect Connection Pooling.

* The driver supports advanced security features, including SSL data encryption.

* The driver supports configurable connection failover protection.

* The driver supports the following data types:
  - Bigint			maps to BIGINT
  - Boolean			maps to BOOLEAN
  - Character			maps to CHAR
  - Character Varying 		maps to VARCHAR
  - Date			maps to DATE
  - Double Precision		maps to DOUBLE
  - Integer			maps to INTEGER
  - Numeric			maps to NUMERIC
  - Real			maps to REAL
  - Smallint			maps to SMALLINT
  - Timestamp			maps to TIMESTAMP

	Notes, Known Problems, and Restrictions

The following are notes, known problems, and restrictions with the driver.

RegisterStatementPoolMonitorMBean Connection Property
The RegisterStatementPoolMonitorMBean connection property registers the
Statement Pool Monitor as a JMX MBean when statement pooling has been enabled
with MaxPooledStatements. This allows you to manage statement pooling with
standard JMX API calls and to use JMX-compliant tools, such as JConsole.
- Valid values are true | false
- If set to true, the driver registers an MBean for the statement pool monitor
  for each statement pool. This gives applications access to the Statement
  Pool Monitor through JMX when statement pooling is enabled.
- If set to false, the driver does not register an MBean for the Statement Pool
  Monitor for any statement pool.
- Registering the MBean exports a reference to the Statement Pool Monitor. The
  exported reference can prevent garbage collection on connections if the
  connections are not properly closed. When garbage collection does not take
  place on these connections, out of memory errors can occur.
- The default is false.
- The data type is boolean.

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:

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 file, change to the directory containing and
enter: chmod +x

Performance Tuning Wizard
The Performance Tuning Wizard is not available with the MongoDB driver. For
information on tuning the driver for performance, see "Performance
Considerations" in the USER'S GUIDE.

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.

Help System Compatibility
Internet Explorer with the Google Toolbar installed sometimes displays the
following error when the browser is closed: "An error has occurred in the
script on this page." This is a known issue with the Google Toolbar and has
been reported to Google. When closing the driver's help system, this error may


The USER'S GUIDE is provided in PDF and HTML versions.

* The PDF version is available on the Progress DataDirect Web site. You can view
  this version using Adobe Reader. (To download Adobe Reader, visit the Adobe
  Web site at

* The HTML version of the guide is installed in the RedshiftHelp subdirectory of
  your product installation directory.
