Please help, I am stuck :confused: !! (0 Replies)

Hi,
I have a problem with memory on AIX 5.3. On this server, we have JDE Edwards (ERP) and Oracle Database (9.2.0.7.0).
We have 4 Gb for physical memory and 3 Gb for paging space.
When I stop all services (JDE, Oracle and all other services), the physical memory is not free (4 Gb)

Hello,
we are using AIX 6.1
On our AIX 6.1 server there are two instance of Oracle, a Websphear, a Java application and informatica are running. Can I find out how much memory each of these are consuming?

Hi,
Can some one please tell me how do I generate a report of the Memory Consumption over a time period:
HP-UX B.11.31 U ia64 0440531406 unlimited-user license
I normally use glance to monitor memory in run time.
Note: I do not have root privileges.
Thanks

Hi,
This thread has been posted before on linuxquestions.org, but no answer, maybe because this is unix question and not linux. I'm posting the same thread here, hope I can get an answer from someone in the meantime, I wish I could post of emergency thread but it needs bits which I don't have :... (6 Replies)
I want to obtain memory consumption history on a HPUX machine.
I know I can access data from the last week with sar
sar -f /var/adm/sa/sa14
I do not know how to get memory usage with sar.
Are there any other ways?
thank you (3 Replies)

set_robust_list
GET_ROBUST_LIST(2) Linux System Calls GET_ROBUST_LIST(2)NAME
get_robust_list, set_robust_list - get/set list of robust futexes
SYNOPSIS
#include <linux/futex.h>
#include <syscall.h>
long get_robust_list(int pid, struct robust_list_head **head_ptr,
size_t *len_ptr);
long set_robust_list(struct robust_list_head *head, size_t len);
Note: There are no glibc wrappers for these system calls; see NOTES.
DESCRIPTION
The robust futex implementation needs to maintain per-thread lists of robust futexes which are unlocked when the thread exits. These lists
are managed in user space; the kernel is notified about only the location of the head of the list.
The get_robust_list() system call returns the head of the robust futex list of the thread whose thread ID is specified in pid. If pid is
0, the head of the list for the calling thread is returned. The list head is stored in the location pointed to by head_ptr. The size of
the object pointed to by **head_ptr is stored in len_ptr.
The set_robust_list() system call requests the kernel to record the head of the list of robust futexes owned by the calling thread. The
head argument is the list head to record. The len argument should be sizeof(*head).
RETURN VALUE
The set_robust_list() and get_robust_list() system calls return zero when the operation is successful, an error code otherwise.
ERRORS
The set_robust_list() system call can fail with the following error:
EINVAL len does not match the size of structure struct robust_list_head expected by kernel.
The get_robust_list() system call can fail with the following errors:
EPERM The calling process does not have permission to see the robust futex list of the thread with the thread ID pid, and does not have
the CAP_SYS_PTRACE capability.
ESRCH No thread with the thread ID pid could be found.
EFAULT The head of the robust futex list can't be stored at the location head.
VERSIONS
These system calls were added in Linux 2.6.17. No library support is provided; use syscall(2).
NOTES
These system calls are not needed by normal applications. No support for them is provided in glibc. In the unlikely event that you want
to call them directly, use syscall(2).
A thread can have only one robust futex list; therefore applications that wish to use this functionality should use the robust mutexes pro-
vided by glibc.
