Hi,
Im working on Solaris 9 on SPARC-32 bit running on an Ultra-80, and I have to find out the following:-
1. Total Physical Memory in the system(total RAM).
2. Available Physical Memory(i.e. RAM Usage)
3. Total (Logical) Memory in the system
4. Available (Logical) Memory.
I know... (4 Replies)

hi, I have done the below, but am confused as to how much memory is "free"
please help

I was running a program and it stopped and showed "Out of Memory!". at that time, the RAM used by this process is around 4G and the free memory size of the machine is around 30G. Does anybody know what maybe the reason? this program is written with Perl. the OS of the machine is Solaris U8. And I... (1 Reply)
Hi guys.
I've a question, if we are using a syscall that receives a string allocated dynamicaly to a determined size, or NUL and it will allocate the apropriate size. We should free the memory or the OS will do it for us?
If a function returns a pointer we should free that poiter when we are done... (7 Replies)

Hi,
I am wondering if there is a way to free up memory in Solaris manually ? the way we can do it in Linux for example :
echo `/bin/date` "************* Memory Info Before *************"
free -m

echo 2 > /proc/sys/vm/drop_caches
echo 3 >... (13 Replies)
If I understand your question correctly, you are asking for an explanation of Solaris memory manager. You'd better ask Oracle that question because you are talking about Solaris kernel internals.
The operating system kernel has no reason to kick a process's memory set out of real memory until... (4 Replies)

DESCRIPTION
The malloc_create_zone() function creates a malloc zone, advising an initial allocation of start_size bytes, and specifying flags The
returned malloc zone can be used to provide custom allocation and deallocation behavior, and to retrieve additional information about the
allocations in that zone. At present there are no client settable flag values recognized by malloc_create_zone(), the flags argument should
always be passed as zero.
The malloc_destroy_zone() function deallocates all memory associated with objects in zone as well as zone itself.
The malloc_default_zone() function returns the default system malloc zone, used by malloc(3), and free(3).
The malloc_zone_from_ptr() function returns a pointer to the malloc zone which contains ptr or NULL, if the pointer does not point to an
allocated object in any current malloc zone.
The malloc_zone_malloc(), malloc_zone_calloc(), malloc_zone_valloc(), malloc_zone_realloc(), malloc_zone_memalign(), and malloc_zone_free()
perform the same task on zone as their non-prefixed variants, malloc(3), calloc(3), valloc(3), realloc(3), posix_memalign(3), and free(3)
perform on the default system malloc zone.
RETURN VALUES
The malloc_create_zone(), malloc_default_zone(), and malloc_zone_from_ptr() functions return a pointer to a malloc_zone_t structure, or NULL
if there was an error.
The malloc_zone_malloc(), malloc_zone_calloc(), malloc_zone_valloc(), malloc_zone_realloc(), and malloc_zone_memalign() functions return a
pointer to allocated memory. If there is an error, they return a NULL pointer. They are not required to set errno.
