Before we start with the WebSphere Application Server installation, we need to ensure the correct installation media is available and that the operating system prerequisites have been met. It is also important to ensure that there is enough free disk space on your Linux file system and that you have a large enough
/tmp folder. A recommended size for the
/tmp folder is 1 Gigabyte; this will also later cater to deployment of large applications. The installer program checks for required space before calling the installation wizard and will inform you that there is not enough disk space; however, it is good to be prepared upfront.
