Driver version 6.0.0.000062 (F000147.U000072)
Enhancements
------------
* The driver has been enhanced to support the Always Encrypted feature.
Beginning with SQL Server 2016, Azure SQL and SQL Server databases support
Always Encrypted, which allows sensitive data to be stored on the server in
an encrypted state such that the data can only be decrypted by an authorized
application. The following are highlights of this enhancement:
- The driver detects all supported native data types stored in encrypted
columns and transparently encrypts values bound to SQL parameters or
decrypts values returned in results.
- The driver supports configurable caching of column encryption keys for
improved performance.
- The driver supports using Java KeyStore and Azure Key Vault as
keystore providers.
You can enable support for Always Encrypted using the following new options:
ColumnEncryption, AEKeyCacheTTL, AEKeystoreClientSecret, AEKeystoreLocation,
AEKeystorePrincipalId, and AEKeystoreSecret. Refer to the user's guide for
more information.
Important: Always Encrypted support requires the driver to run on a Java
Virtual Machine (JVM) that is Java SE 8 or higher.
For a list of limitations for the Always Encrypted feature, see "Notes,
Known Problems, and Restrictions."
* The version of Bouncy Castle that ships with the driver has been upgraded to
1.60, which fixes the following security vulnerabilities:
- CVE-2018-1000613
- CVE-2018-1000180
- CVE-2017-13098
This upgrade is available starting in build 5.1.4.000120 of the driver. For
more information on the vulnerabilities resolved by this upgrade, refer

Enhancements
------------
* The driver has been enhanced to connect to Microsoft Azure SQL
Data Warehouse and Microsoft Analytics Platform System data sources.
* The driver has been enhanced to support Always On Availability Groups.
Introduced in SQL Server 2012, Always On Availability Groups is a replica
database environment that provides a high-level of data availability,
protection, and recovery.
* The driver has been enhanced to support Azure Active Directory authentication
(Azure AD authentication). Azure AD authentication is an alternative to SQL
Server Authentication that allows administrators to centrally manage user
permissions to Azure SQL Database data stores.
* The driver has been enhanced to support Kerberos Constrained Delegation.
Sometimes referred to as impersonation, Constrained Delegation allows the
driver to establish a connection with credentials passed via a GSSCredential
object.
* For Kerberos authentication environments, the following changes have been
implemented.
- The driver no longer sets the java.security.auth.login.config system
property to force the use of the installed JDBCDriverLogin.conf file as
the JAAS login configuration file. By default, the driver now uses the
default JAAS login configuration file for Java, unless you specify a
different location and file using the java.security.auth.login.config
system property.
- The driver no longer sets the java.security.krb5.conf system property to
force the use of the krb5.conf file installed with the driver jar files
in the /lib directory of the product installation directory.
* Added the RegisterStatementPoolMonitorMBean connection property. 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.
* Support for result set holdability has been added to the driver.
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).
* Support for DLL-based NTLM authentication has been deprecated. As a result,
the AuthenticationMethod property has been updated to no longer support the
ntlm value. If the value is specified, the driver throws an error when
attempting to connect.
Notes, Known Problems, and Restrictions
The following are notes, known problems, and restrictions with the 6.0.0
release of the driver.
Always Encrypted Limitations
----------------------------
The following limitations apply to the current implemantation of Always
Encrypted support:
* No support for encrypted parameters in stored procedures
* No support for encrypted values in updateable result sets
* No support for Windows certificate store or custom keystore providers
* No support for enabling Always Encrypted on individual statements. Support for
encrypted columns can only be set at the connection level.
Using Bulk Load
---------------
For optimal performance, minimal logging and table locking must be enabled.
Refer to the following Web sites for more information about enabling minimal
logging:
http://msdn.microsoft.com/en-us/library/ms190422.aspx
http://msdn.microsoft.com/en-us/library/ms190203.aspx
Table locking, a bulk load option, is enabled by default. Table locking prevents
other transactions from accessing the table you are loading to during the bulk
load. See "Bulk load properties" in the user's guide for information about
configuring the driver for bulk load operations.
System.exit() method and Process Termination
--------------------------------------------
The System.exit() method ensures that all registered shutdown hooks are run.
Applications terminate faster when System.exit(0) is used. When applications
omit the System.exit() call, the termination process may linger for about 10
seconds before exiting.
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.
