Start Options

In some situations, performance can be improved by using large page sizes. The start options to use depend on your processor architecture. The following examples show the options to start the 32–bit Enterprise Server and the 64–bit Enterprise Server with 4–Mbyte pages.

• To start the 32–bit Enterprise Server with 4–Mbyte pages, use the following options:

  LD_PRELOAD_32=/usr/lib/mpss.so.1 ; 
  export LD_PRELOAD_32; 
  export MPSSHEAP=4M; 
  ./bin/startserv; 
  unset LD_PRELOAD_32; 
  unset MPSSHEAP

• To start the 64–bit Enterprise Server with 4–Mbyte pages, use the following options:

  LD_PRELOAD_64=/usr/lib/64/mpss.so.1; 
  export LD_PRELOAD_64; 
  export MPSSHEAP=4M; 
  ./bin/startserv; 
  unset LD_PRELOAD_64; 
  unset MPSSHEAP
