Modify Kernel Parameters using expressions

Modify Kernel Parameters using expressions

Hi All,

 

Please I'm trying to modify some kernel parameters using an expression that contain brackets (( )) but i keep getting error when applying the expression, kindly assist? here is the error...

 

 Enter Value/Expression OR q(quit)   = ((8 * NPROC + 2048) +1024)

     The Expression is not valid

     Enter Value/Expression OR q(quit)   = ((8*nproc+2048)+1024)

     The expression evaluated to: 35840

     Do you want to save the current kernel configuration ? (y/n/q)[y] = y

     Enter Comments =

     Command Preview: /usr/sbin/kctune -h -B ncsize=((8*nproc+2048)+1024)

     Do you want to proceed ? (y/n) [n] = y

I see no brackets here, just parentheses.

Hmm, I would have thought this would be quoted to protect the expression.

You could just add a space between the two left parentheses?
