May provide some ideas on how: http://stackoverflow.com/questions/22407678/check-if-swap-space-exist-in-bash May also need to look at entire free memory issue.

My opinion is that if the system has swap in place then skip the swap setup completely. Ideally this is optional and user defined location and size but probably too complicated for the value. My vote is to disable if the system has swap already since its not mandatory for xe.

@GasparYYC I agree with you but we're looking for the right command to detect both that saw is enabled and that it meets the minimum requirement. If not XE will fail to install.

@martindsouza My mistake, I did not find SWAP as a requirement for xe but I looked at the Windows document and not the Linux. I agree, some logic needs to be in place for that work properly. As per installation guide: https://docs.oracle.com/cd/E17781_01/install.112/e18802/toc.htm#XEINL103

2.1.2 Swap Space Requirements Minimum swap space required for Oracle Database XE is 2 GB or twice the size of RAM, whichever is lesser.

Interesting workaround for the swap issue in this Oracle XE dockerfile setup

https://github.com/pmdevel/oracle-xe/blob/master/Dockerfile#L13

  1. create backup of free command
  2. replace with script that always echos 2048
  3. execute the Oracle XE install
  4. restore the original free
