To increase the shared memory to 512 MB, run the following commands:
echo 536870912 > /proc/sys/kernel/shmmax echo 536870912 > /proc/sys/kernel/shmall
Where the file shmmax contains the maximum size of a single shared memory segment, and shmall contains the total shared memory to be made available.
This value is large enough for a standard HADB node that uses default values. If the default values are changed, consider changing these values, as well.
