Hi, All

I'm working with MonetDB Server v5.6.0, based on kernel 1.24.0 over RedHat Linux Enterprise 5.2. Would you tell me timing which in the memory is allocated and timing in which the memory is deallocated, or is there an instruction that deallocate the memory?

I'm sorry but your question is a bit vague. MonetDB claims memory when it needs it, it doesn't have an easy deallocate interface. It sort of assumes its allone on your system/pc etc. There are some settings in monetdb5.conf which control the maximum used memory. See your monetdb5.conf for more info.

# gdk_mem_bigsize & gdk_vm_minsize will be set/limited to # 1/2 of the physically available amount of main-memory # during start-up in src/tools/mserver.mx # memory chunks of size >= gdk_mem_bigsize (in bytes) will be mmaped # anonymously #gdk_mem_bigsize=262144 # memory chunks of size >= gdk_vm_minsize (in bytes) will be mmaped; #gdk_vm_minsize=137438953472 # for 32 bit systems try to claim 3G of (virtual) memory;
