Cause

WebTrends currently does not support Itanium or Itanium 2 processors from Intel. These two processors are true 64-bit processors and do not support the 32-bit instruction set, which means these processors are not backwards-compatible. Operating systems do have a compatibility mode for 32-bit applications, but this is not certified for WebTrends to run on.

Two exceptions to this are AMD 64-bit processors and Intel EM64T. AMD processors are backwards-compatible and the Intel EM64T processor is a 32-bit processor.

Resolution

Below are the maximum number of processors and amount of memory each OS supports:

OS Processors Memory Platform
Windows Server 2003 Web Edition 2 2 GB x86 (32-bit)
Windows Server 2003 Standard Edition 4 4 GB x86 (32-bit)
Windows Server 2003 Enterprise Edition Edition 8 32 GB x86 (32-bit)
Windows Server 2003 Datacenter Edition 32 64 GB x86 (32-bit)
Windows Server 2003 Standard x64 Edition 4 32 GB x64 (64-bit)
Windows Server 2003 Enterprise x64 Edition 8 1 TB x64 (64-bit)
Windows Server 2003 Datacenter x64 Edition 64 1 TB x64 (64-bit)
Windows Server 2003 Enterprise 64-Bit Edition 8 1 TB Itanium (64-bit)
Windows Server 2003 Datacenter 64-Bit Edition 64 1 TB Itanium (64-bit)

The x64 versions of 2003 support up to 4GB of memory per process, however WebTrends will only use 3GB per analysis.

Example:
If WebTrends is configured to have two concurrent tasks enabled and only 5GB of system memory, it is possible for WebTrends to exceed 5GB memory usage and cause analysis failure. As a result, this may cause stability issues with WebTrends. As it has not been tested, this is not a supported configuration.
