Information in this document applies to any platform.
Increasing "swap" space on guest vServers in an Exalogic rack can be needed to accommodate applications that utilize large amounts of swap space.
Documentation on how to increase swap space can be found in the Exalogic document below:
The documentation above will allow you to "extend" swap space to 2GB only regardless of the size of the volume size allocated to be used.
By default, the Oracle Linux 7 guest vServer template already is configured with 4GB of swap space.
For example, if you wish to increase swap space from 4GB to 10GB, and using a 6GB volume, when following the documentation above, it will only extend this by 2GB, from 4GB to 6GB instead of 10GB.
Below you will find a different way to make this incrementation by using a 6GB volume attached and creating a new "Volume Group" similar to creating a "/tmp" partition (https://docs.oracle.com/cd/E18476_01/doc.220/e25258/GUID-0C1EF990-1EA7-426D-9208-083D07FF249D.htm#ELCLD77345).
