Manipulating swap space on a running Solaris system

Listing swap files in use

The following command will list all active swap files:

  swap -l

with output looking like this:

  swapfile             dev  swaplo blocks   free
  /dev/md/dsk/d10     85,10     16 8389632 8389632

Adding swap space

So you need more swap temporarily. Here's how:

1. Make a file to add to swap

  mkfile 2g /export/tempfile

This will crate a 2Gb file.

2. Add the file to the swap pool

  swap -a /export/tempfile

then check it worked with

  swap -lswapfile             
  dev  swaplo blocks   free
  /dev/md/dsk/d10     85,10     16 8389632 8389632
  /export/tempfile      -       16 6291440 6291440

Delete a swap file

Finished with your temporary swap file. Delete it:

 swap -d /export/tempfile
