System requirements

Hardware requirements

HCL Informix Warehouse Accelerator runs on Linux Intel x86_64(EM64T/AMD64) and IBM POWER (Little Endian) systems. The Informix database server can be collocated on those systems, or it can run on one of a number of UNIX operating systems.

Important:
  • Both the Informix and Informix Warehouse Accelerator versions must be at the same release and fix pack level. For example: Informix 14.10.FC5 and Informix Warehouse Accelerator 14.10.FC5.
  • Informix Warehouse Accelerator keeps compressed data in memory. The computer where Informix Warehouse Accelerator is installed must be configured with enough memory to accommodate the size of the data marts. For information, see Configuring memory for Informix Warehouse Accelerator in the HCL Informix documentation:

The computer on which you install Informix Warehouse Accelerator must have a CPU with the Streaming SIMD Extensions 3 (SSE3) instruction set. To verify what is installed on the computer, you can run the cat /proc/cpuinfo command and look at the flags that are returned.

Informix Warehouse Accelerator can accelerate queries for an Informix database server that runs on one of the following operating systems:
  • AIX® 64-bit
  • Linux x86_64 64-bit
  • Linux x86_64 64-bit
  • Linux PPC64LE 64-bit
  • Solaris SPARC 64-bit
