By default when you execute yum history command, you would only see the time and actions (update, install etc.) for the yum packages.
# yum history
.....
ID | Login user | Date and time | Action(s) | Altered

19 | [oracle] | 2017-07-08 14:35 | Install | 1 EE
18 | [oracle] | 2017-07-08 00:32 | Install | 1
To also view the yum commands executed in the out put we need to add history_list_view=cmds entry to /etc/yum.conf file. By default, this parameter is not added in the yum configuration file.
# vi /etc/yum.conf history_list_view=cmds
If you now check, you can find the commands like “install, update” in the second column. You would also get the options used with the command like –exclude.
# yum history
