The swappiness level of the Linux kernel determines how likely it is to swap memory pages out. Setting a low value can improve the performance of Oracle SOA Suite.
You will need to be running Oracle SOA Suite 11g on a Linux box, and have
sudo access in order to change the kernel settings.
To set the Linux kernel swappiness to low, perform the following steps:
$ cat /proc/sys/vm/swappiness 60
/etc/sysctl.conf, and set the property
vm.swappinessto a lower value. We suggest starting with
0if you have plenty of physical memory on the machine.
