Adding Swap Space on a Solaris System

Adding Swap Space on a Solaris System

1. Become a superuser (root) by typing:

   % su
   Password: root-password

2. Create a file in a selected directory to add swap space by typing:

   mkfile number[m|k|b] /directory/swap-file-name

   where number is an amount of swap space, followed by either m for megabyte, k for kilobyte, or b for block. The directory is a directory in which you have permission to add swap space. The swap-file-nameis the name of the swap file you are creating.
   For example, to create a 16-megabyte swap file named 16mswapin the foodirectory, type the following:
   

   mkfile 16m /foo/16mswap

   See the mkfile(1M) man page for more information.
3. Verify that the file was created by typing:

   ls -l /directory/swap-file-name

   The new file appears in the directory. For example:
   

   ls -l /foo/16mswap
   -rw------T   1 root     other    16777216 Dec 12 14:24 /foo/16mswap

4. Run the swap command to specify the additional swap space by typing:

   swap -a /directory/swap-file-name

5. Verify that the extra swap space was added by typing:

   swap -s

   The output shows the allocated swap space. For example:
   

   swap -s
   total: 289336k bytes allocated + 27008k reserved = 316344k used, 298336k available
