>Comment peut -on changer les valeurs donn�es par ipcs
>(s�maphores, messages, share memory segments) ?
voil� des infos que j'ai trouv� sur le site Oracle
Je suis heureux de voir que quelqu'un d'autre s'int�resse � Oracle. J'ai,
install� il ya maintenant une petite ann�e la version 8.0.5. Je n'ai pas eu
de probl�mes particuliers (hormis le fait que j'ai du installer des rpms de
d�veloppement).
C'�tait la version 5.1 de mandrake. Je ne me souviens plus de la version du
noyau.
Quelle glibc as tu? 2.0 2.1? As tu patch� si tu as la 2.1?
cordialement,
Christian
Where To Find Linux Kernel Parameters
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The Oracle for Linux installation guide outlines suggested values for Linux
kernel parameters. There is no direct way to query these values or adjust
them
on a running system by means of a configuration utility. Instead, you must
look in the header files of the Linux source code to find the current
values.
The location of each parameter is described below. You should not have to
change these values from the default supplied with most Linux distributions.
In order to verify that the files have not been modified without a kernel
rebuild, please ensure the kernel is more recent than the last modification
of the header file. The kernel is found in /boot and is usually of the form
"vmlinuz-2.0.nn-n".
Should you need to change any parameters, you must edit the appropriate
header
file and rebuild the kernel.
Parameter | Location
----------------------------------------------------------------------------
--
SHMMAX |
The maximum size (in bytes) of a | /usr/src/linux/include/asm/shmparam.h
single shared memory segment. |
----------------------------------------------------------------------------
--
SHMMIN |
The minimum size (in bytes) of a | /usr/src/linux/include/asm/shmparam.h
single shared memory segment. |
----------------------------------------------------------------------------
--
SHMMNI |
The number of shared memory | /usr/src/linux/include/asm/shmparam.h
identifiers. |
----------------------------------------------------------------------------
--
SHMSEG |
The maximum number of shared | /usr/src/linux/include/asm/shmparam.h
memory segments that can be |
attached by a process. |
----------------------------------------------------------------------------
--
SEMMNS |
The number of semaphores in the | /usr/src/linux/include/linux/sem.h
system. |
----------------------------------------------------------------------------
--
SEMMNI |
The number of semaphore set |
identifiers in the system. SEMMNI | /usr/src/linux/include/linux/sem.h
determines the number of semaphore |
sets that can be created at any |
one time. |
----------------------------------------------------------------------------
--
SEMMSL |
The maximum number of semaphores |
that can be in one semaphore set. | /usr/src/linux/include/linux/sem.h
Should be equal to the maximum |
number of Oracle processes. |
