ProcedureAdding 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
