Hi,?

I am using kdb+ 32 bit trail version on 64 bit machine with windows 7 operation system.

My system have 32 GB ram but when I running kdb+ i can see the following information

C:\q\w32\>q ?-p 1234

KDB+ 3.1 2013.07.18 Copyright (C) 1993-2013 Kx Systems

w32/ 8()core 4095MB sun sun-pc 1 PLAY 2013.10.16

How can i increase memory allocation for kdb+?

Thanks

The non-commercial release is a 32bit processes and as such it is limited to a 32bit address space.  
To have access to more memory, you would need to license the commercial 64bit release.

thanks
