AWS EC2 Create Swap File

While creating PeopleSoft Upgrade Maintenance (PUM) environments using the DPK’s from Oracle, they require that you have a swapfile in order to complete the install.  Sometimes it will warning you and sometimes it won’t. We run the DPK’s using the OEL 7.3 OS, and these instructions will create a swapfile.

1. Login to EC2 using SSH (switch to root user)

2. Create a file for the swapfile:
fallocate -l 2G /placewithspace/swapfile

3. Change the permissions on the swapfile:
chmod 600 /placewithspace/swapfile

4. Allocate the file as a swap file:
mkswap /placewithspace/swapfile -f

5. Turn the swap file on:
swapon /placewithspace/swapfile

6. Check swap file is active:
swapon -s

Enjoy DPK installing.
