Initially, swap space is allocated as part of the Oracle Solaris installation process. In a ZFS root environment, the default swap size is generally in the 512 MB to 2 GB range.
For general guidelines on allocating swap space, see Planning for Swap Space.
After the system is installed, swap areas and swap files are listed in the /etc/vfstab file. They are activated by the /sbin/swapadd script when the system is booted.
An entry for a swap device in the /etc/vfstab file contains the following:
The full path name of the swap slice or swap file on system with a UFS root file system or a swap volume path name on a system with a ZFS root file system
File system type of the swap slice or swap file
The file system that contains a swap file must be mounted before the swap file is activated. So, in the /etc/vfstab file, ensure that the entry that mounts the file system comes before the entry that activates the swap file.
