Hi,
I have HP-UX 11i v3 running on ia64. One of my application is 32-bit and I want to increase the memory allocation of this file upto 2GB. I am contentiously receiving an error message of Out of Memory.
Can you please explain the procedure what kernel configuration( like maxdsize or maxdsize_64) i need to set and also do i need to set anything on the application binary ?
Thanks in advance.
My file chatr is as follows

Hi folks,
We are using following listed configurations for a particular application.
HP-UX 11i
Sun Java 2 SDK Standard Edition 1.4.1 (version shipped with WebLogic 8)
Oracle 9i Release 2 (Oracle 9.2.0)
BEA WebLogic Server 8.1 SP3
It seems a memory leak when we use above configurations.... (1 Reply)
Hellp all,
if there is 3G memory in my Unix server I want to know if all the 3G space can be used by ong sigle process. As i know, in Windows, one process can only access at most 1G memory despite there is probably more than 1G memory is equipped. (1 Reply)
Hi all,
I have a HP-UX Server with 4 gigabytes of physical RAM. When I use the 'Glance' utility to see what my memory utilization is, my memory usage shows up maxed out at 99%. I shut off all the known processes that I'm running on that box and the memory utilization is still at 78% (with Swap... (1 Reply)

Hi everyone,
I'm not new to C programming, but I'm having question regarding the memory allocation of a pointer variable which, for instance, will be declared in main(), but its memory will be allocated in subroutine.
To clearify my question, I provide a small working example:

Hi Experts
I need some help in static memory allocation in C. I have a program in which I declared 2 variables, one char array and one integer. I was little surprised to see the addresses of the variables.
First:
int x;
char a;
printf("%u %u\n', &x, a);
I got the addresses displayed... (2 Replies)
Hello Guys
I have a small confusion in the dynamic memory allocation concept.
If we declare a pointer say a char pointer, we need to allocate adequate memory space.
char* str = (char*)malloc(20*sizeof(char));
str = "This is a string";
But this will also work.
char* str = "This... (2 Replies)
When we dynamically allocate the memory say 100 integers say
int *x = new int(1000);
then does entire chunk of memory gets allocated at once after the completion of the statement?
I mean will the the concept of page fault come into picture over here? (3 Replies)
I want to run a C program on my linux machine. I want to allocate specific heap size for that process (C program) to run.
How can I do that?
I know in Java same can be done using -Xmx option.
There may be some option which I can specify in the C program like Java or may be in linux process. (8 Replies)

plock
plock(2) System Calls Manual plock(2)NAME
plock() - lock process, text, data, stack, or shared library in memory
SYNOPSIS DESCRIPTION
The system call allows the calling process to lock the text segment of the process (text lock), its data segment (data lock), or both its
text and data segment (process lock) into memory. Stack segments are also locked when data segments are locked. Shared library text and
shared library data segments (shlib lock) can also be locked. Locked segments are immune to all routine swapping. also allows these seg-
ments to be unlocked.
The effective user ID of the calling process must be a user with the privilege.
op must be one of the following:
Lock text and data segments into memory (process lock)
Lock text segment into memory (text lock)
Lock data segment into memory (data lock)
Remove locks
Lock shared library text and shared library data segments (shared library lock)
Lock text, data and shared library text and shared library data segments
into memory (process and shared library lock)
Lock text, shared library text and shared library data segments into memory
(text and shared library lock)
Lock data, shared library text and shared library data segments into memory
(data and shared library lock)
Although and the family of functions may be used together in an application, each may affect the other in unexpected ways. This
practice is not recommended.
Security Restrictions
Some or all of the actions associated with this system call require the privilege. Processes owned by the superuser have this privilege.
Processes owned by other users may have this privilege, depending on system configuration. See privileges(5) for more information about
privileged access on systems that support fine-grained privileges.
RETURN VALUE
returns the following values:
Successful completion.
Failure.
The requested operation is not performed. is set to indicate the error.
ERRORS
If fails, is set to one of the following values.
op is equal to and a process lock, a text lock, or a data lock already exists on the calling process.
op is equal to and a text lock or process lock already exists on the calling process.
op is equal to and a data lock, or process lock already exists on the calling process.
op is equal to and no type of lock exists on the calling process.
op is equal to and there are no unlocked shared library segments in the calling process.
op is equal to and a process lock, a text lock, or a data lock already exists on the calling process.
op is equal to and a text lock or process lock already exists on the calling process.
op is equal to and a data lock, or process lock already exists on the calling process.
op is not equal to one of the values specified in
is not allowed in a
window. See vfork(2).
There is not enough lockable memory in the system
to satisfy the locking request.
The effective user ID of the calling process
is not a user with the privilege.
EXAMPLES
The following call to locks the calling process in memory:
