I can't help you with the specific kernel parameter since I don't know HPUX very well. You'll have to ask your DBA or look it up.
But, I think I know what is going on. Oracle sets its shared memory area when it starts up. Even if it looks to the OS like there is 5GB free, if you take any of it which Oracle expected to be able to use Oracle will complain. If you are setting aside some memory for caching as you described, you probably have to decrease the shared global area in Oracle to compensate.
Hope that helped, I know it wasn't long on details . . .

I am writing a shared library in Linux (but compatible with other UNIXes) and I want to allow multiple instances to share a piece of memory -- 1 byte is enough. What's the "best" way to do this? I want to optimize for speed and portability.
Obviously, I'll have to worry about mutual exclusion. (0 Replies)

NAME
_nc_freeall _nc_free_and_exit - curses memory-leak checking
SYNOPSIS
#include <curses.h>
void _nc_freeall(void);
void _nc_free_and_exit(int);
DESCRIPTION
These functions are used to simplify analysis of memory leaks in the ncurses library. They are normally not available; they must be con-
figured into the library at build time using the --disable-leaks option. That compiles-in code that frees memory that normally would not
be freed.
Any implementation of curses must not free the memory associated with a screen, since (even after calling endwin), it must be available for
use in the next call to refresh. There are also chunks of memory held for performance reasons. That makes it hard to analyze curses ap-
plications for memory leaks. To work around this, one can build a debugging version of the ncurses library which frees those chunks which
it can, and provides these functions to free all of the memory allocated by the ncurses library.
The _nc_free_and_exit function is the preferred one since some of the memory which is freed may be required for the application to continue
running. Its parameter is the code to pass to the exit routine.
RETURN VALUE
These functions do not return a value.
PORTABILITY
These functions are not part of the XSI interface.
