Check the kernel parameter shmall in the /etc/sysctl.conf file.

The parameter shmall is the total shared memory in pages, that the system can use at one time.

$cat /proc/sys/kernel/shmmax

 

Command to check the page size,

$ getconf PAGE_SIZE

 

As per the Oracle,

 

shmall = Total_RAM/Page_Size

 

Change kernel.shmall = 1024 * 1024 * 1024 * RAM_Size / PAGE_Size

 

Edit the shmall parameter in the /etc/sysctl.conf file

 

For Example,

 

$ su – root

vi /etc/sysctl.conf file:

kernel.shmall=16777216

 

save the file and execute the below command to effect the changes done,

 

# sysctl -p
