OUI Prerequisite Check
To make sure that the database server is ready for installing Oracle home, we can perform a dry run to determine the fulfillment of prerequisites by Oracle universal installer (OUI).
Here we run the installer with -executePrereqs flag by the following ways.
Either way runs only prerequisite check, nothing is applied.
Using GUI
We can visually see items which can not pass the prerequisite check.
[oracle@test ~]$ $ORACLE_HOME/runInstaller -executePrereqs
Launching Oracle Database Setup Wizard...
If the option "Ignore All" in the screen can be checked, the item is ignorable.
Silent Mode
If GUI cannot be an option in your situation, e.g. no X window (X11), you may also check the prerequisite in silent mode.
[oracle@test ~]$ $ORACLE_HOME/runInstaller -executePrereqs -silent
Launching Oracle Database Setup Wizard...
[WARNING] [INS-13014] Target environment does not meet some optional requirements.
CAUSE: Some of the optional prerequisites are not met. See logs for details. /tmp/InstallActions2023-01-17_07-05-59PM/installActions2023-01-17_07-05-59PM.log
ACTION: Identify the list of failed prerequisite checks from the log: /tmp/InstallActions2023-01-17_07-05-59PM/installActions2023-01-17_07-05-59PM.log. Then either from the log file or from installation manual find the appropriate configuration to meet the prerequisites and fix it manually.
For more information about verification result, we inspect the log file.
[oracle@test ~]$ vi /tmp/InstallActions2023-01-17_07-05-59PM/installActions2023-01-17_07-05-59PM.log

INFO: [Jan 17, 2023 7:06:05 PM] Cause: The swap size found does not meet the minimum requirement.

It's also the SWAP size problem, such failed prerequisites can be ignored in silent mode.
