Environment-Specific Information

The sections "For Windows Users" and "For UNIX and Linux Users" contain information specific to your operating environment.

The following sections refer to threading models. Refer to "Threading" in the DataDirect Connect for ODBC and Connect XE for ODBC Reference for an explanation of threading.

For Windows Users

The drivers are 32-bit drivers. All required network software supplied by your database system vendors must be 32-bit compliant.
If your application was built with 32-bit system libraries, you must use 32-bit drivers. If your application was built with 64-bit system libraries, you must use 64-bit drivers. When using DataDirect Connect or Connect XE for ODBC, the database you are connecting to can be either 32-bit or 64-bit enabled.
The following processors are supported:
x86: Intel
x64: Intel and AMD
The following operating systems are supported for DataDirect Connect for ODBC:
Windows Vista, all Editions
Windows XP Home Edition and Professional Service Pack 1 and higher
Windows Server 2003 Enterprise and Datacenter Editions
Windows 2000 Service Pack 1 and higher
Windows NT 4.0 Service Pack 5 and higher
Windows Me
Windows 98
The following operating systems are supported for DataDirect Connect XE for ODBC:
Windows Vista, all Editions
Windows XP Professional Service Pack 1 and higher
Windows Server 2003 Enterprise, Datacenter, Web and Small Business Editions
Windows 2000 Professional and Server Service Pack 4
An application compatible with components built using Microsoft Visual Studio 2005 compiler version 8 and the standard Win32 threading model

Setup of the Drivers

The drivers must be configured before they can be used. See "Quick Start Connect" for information about using the Windows ODBC Administrator. See the individual driver chapters for details about driver configuration.

Driver Names

The prefix for all DataDirect Connect and Connect XE for ODBC driver file names is IV. The file extension is .DLL, which indicates that they are dynamic link libraries. For example, the Sybase Wire Protocol driver file name is IVASEnn.DLL, where nn is the revision number of the driver.

Refer to the readme file shipped with the product for the file name of each driver.

For UNIX and Linux Users

The drivers are 32-bit drivers. All required network software supplied by your database system vendors must be 32-bit compliant.
If your application was built with 32-bit system libraries, you must use 32-bit drivers. If your application was built with 64-bit system libraries, you must use 64-bit drivers. When using DataDirect Connect for ODBC or Connect XE for ODBC, the database to which you are connecting can be either 32-bit or 64-bit enabled.

AIX

IBM POWER processor
AIX 5L operating system, versions 5.3, 5.2, and 5.1
An application compatible with components built using CSet++ 5.0 and the AIX native threading model

NOTE FOR TERADATA USERS: When compiling an application on AIX for use with the driver for the Teradata database, you must use the -brtl option. For example:

cc -o pgm pgm.o  -brtl -lodbc 

or

ld -o  pgm -brtl  pgm.o -lodbc 

HP-UX

The following processors are supported:
PA-RISC
Intel Itanium II (IPF)
The following operating systems are supported:
For PA-RISC: HP-UX 11i (11.23 and 11.11) and 11
For IPF: HP-UX IPF 11i, versions 2 and 1.6 (B.11.23 and B.11.22)
For PA-RISC: An application compatible with components built using HP aC++ 3.30 and the HP-UX 11 native (kernel) threading model (posix draft 10 threads)
For IPF: An application compatible with components built using HP aC++ 5.36 and the HP-UX 11 native (kernel) threading model (posix draft 10 threads)

NOTE: Only the following drivers are supported on IPF: Informix Wire Protocol, Oracle Wire Protocol, SQL Server Wire Protocol, Sybase Wire Protocol, and Oracle.

Linux

The following processors are supported:
x86: Intel
x64: Intel and AMD
The following operating systems are supported:
Red Hat Enterprise Linux 4.0 and 3.0
SUSE Linux Enterprise Server 10.0, 9.0, and 8.0
An application compatible with components built using g++ GNU project C++ and the Linux native pthread threading model (Linuxthreads).

NOTE: All drivers are supported on Linux except for the Informix driver.

Solaris

The following processors are supported:
Sun SPARC
x86: Intel
x64: Intel and AMD
The following operating systems are supported:
For Sun SPARC: Sun Solaris 10, 9, and 8
For x86/x64: Sun Solaris 10
For Sun SPARC: An application compatible with components built using Sun Workshop v. 6 update 2 and the Solaris native (kernel) threading model
For x86/x64: An application compatible with components built using Sun C++ 5.8 and the Solaris native (kernel) threading model

NOTE: Only the following drivers are supported on x86/x64: DB2 Wire Protocol, Oracle Wire Protocol, SQL Server Wire Protocol, and Sybase Wire Protocol.

HP-UX 11 aCC

The ODBC drivers require certain runtime library patches. The patch numbers are listed in the readme file for your product. HP-UX patches are publicly available from the HP Web site (www.hp.com) or FTP site (ftp://i3107ffs.external.hp.com).

HP updates the patch database regularly; therefore, the patch numbers in the readme file may be superseded by newer versions. If you search for the specified patch on an HP site and receive a message that the patch has been superseded, download and install the replacement patch.

Setup of the Environment and the Drivers

On UNIX and Linux, several environment variables and the system information file must be configured before the drivers can be used. See "Quick Start Connect" for a brief description of these variables and information about using the DataDirect ODBC Data Source Administrator for UNIX/Linux. See the individual driver chapters for details about driver configuration. See "Configuring the Product on UNIX/Linux" for complete information about using the drivers on UNIX and Linux.

Driver Names

The DataDirect Connect and Connect XE for ODBC drivers are ODBC API-compliant dynamic link libraries, referred to in UNIX and Linux as shared objects. The prefix for all ODBC driver file names on UNIX and Linux is iv. The driver file names are lowercase and the extension is .so or .sl. This is the standard form for a shared object. For example, the Sybase driver file name is ivasenn.so on all platforms except HP-UX, in which case it is ivasenn.sl, where nn is the revision number of the driver.

Refer to the readme file shipped with your DataDirect product for the file name of each driver.
