9395.0. "How to change max value of sysconfigtab?" by OHFSS1::KANNAPAREDDY () Fri Apr 04 1997 16:48

    
    Greetings Folks,
    
    	I have strange problem. I would like to change the value
    	of "dump-sp-threshold" atrribute from the "generic" subsytem,
    	to a value higher than the default of "4096". To my dismay,
    	the MAXIMUM value if configured to be "4096" and I cannot
    	find a way to raise this upper limit. 
    	Is there a way to change the "max value" of sysconfig parameter?
    	(I found out the max value from the sysconfig -Q command). I am
    	thinking this may not be that easy if it is "burned" in
    	"generic.mod". 
    	
    	Ironically, in all the docs the ex. they give to change a 
    	"sysconfig" attr. value dynamically is "dump-sp-threshold"
    	and the ex. show how to increase it from 4096 to 20xxx blocks!!!!
    
    
    	cheers

9395.1How about manually chaning it?NETRIX::"[email protected]"SriFri Apr 04 1997 17:5623
Hi,

	First make sure that the syntax in /etc/sysconfigtab is
right. In your case, the /etc/sysconfigtab should have the lines
similar to:

generic:
	dump-sp-threshold = 40960

Just in case if you noticed its BURNED in., you can manually
change that value as follows:

dbx -k /vmunix /dev/mem
(dbx) assign dump_sv_swap_min= 40960
(dbx) patch dump_sv_swap_min= 40960
(dbx) quit

This should enable your /vmunix with the new value.

Regards
Sri
