Is this a known issue and is there any patch available for this? (0 Replies)

Hi,
I'm trying to learn how to manage memory when I have to deal with lots of data.
Basically I'm indexing a huge file (5GB, but it can be bigger), by creating tables that
holds offset <-> startOfSomeData information. Currently I'm mapping the whole file at
once (yep!) but of course the... (1 Reply)

Is there a way by which we could map Oracle SGA memory into physical files in solaris.
We could find these physical files in /dev/shm/ folder in linux environment but they are missing in solaris. (1 Reply)

getpagesize
GETPAGESIZE(2) Linux Programmer's Manual GETPAGESIZE(2)NAME
getpagesize - get memory page size
SYNOPSIS
#include <unistd.h>
int getpagesize(void);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
getpagesize(): _BSD_SOURCE || _XOPEN_SOURCE >= 500
DESCRIPTION
The function getpagesize() returns the number of bytes in a page, where a "page" is the thing used where it says in the description of
mmap(2) that files are mapped in page-sized units.
The size of the kind of pages that mmap(2) uses, is found using
#include <unistd.h>
long sz = sysconf(_SC_PAGESIZE);
(most systems allow the synonym _SC_PAGE_SIZE for _SC_PAGESIZE), or
#include <unistd.h>
int sz = getpagesize();
CONFORMING TO
SVr4, 4.4BSD, SUSv2. In SUSv2 the getpagesize() call is labeled LEGACY, and in POSIX.1-2001 it has been dropped; HP-UX does not have this
call. Portable applications should employ sysconf(_SC_PAGESIZE) instead of this call.
NOTES
Whether getpagesize() is present as a Linux system call depends on the architecture. If it is, it returns the kernel symbol PAGE_SIZE,
whose value depends on the architecture and machine model. Generally, one uses binaries that are dependent on the architecture but not on
the machine model, in order to have a single binary distribution per architecture. This means that a user program should not find
PAGE_SIZE at compile time from a header file, but use an actual system call, at least for those architectures (like sun4) where this depen-
dency exists. Here libc4, libc5, glibc 2.0 fail because their getpagesize() returns a statically derived value, and does not use a system
call. Things are OK in glibc 2.1.
