Supported operating systems for database application development

You can develop DB2® database applications on the following operating systems:

• AIX®
• HP-UX
• Linux
• Solaris
• Windows

There are restrictions about when you can use available 32-bit or 64-bit architectures:

• With Linux on x86 and Windows operating systems on x86, only 32-bit DB2 database instances are supported. On 64-bit Windows operating system, both the 32-bit and 64-bit instances are supported. On all other operating systems, only 64-bit DB2 database instances are supported.
• You can run 32-bit database applications with either a 32-bit or 64-bit version of one of the IBM® data server clients and develop with either the 32-bit or 64-bit IBM Data Server Client
• The steps for building applications in a 32-bit environment are sometimes different from the steps for building applications in a 64-bit environment.
