Questions about WebLogic Server's directories and files, $ORACLE_HOME/modules , $ORACLE_HOME/utils

Dear Oracle Support,

I hope this message finds you well.

I performed a silent installation of WebLogic Server 14c using the following response file.

—————————————————————————————————————
[ENGINE]
Response File Version=1.0.0.0.0

[GENERIC]
ORACLE_HOME=/opt/app/Oracle/Middleware

INSTALL_TYPE=WebLogic Server

DECLINE_SECURITY_UPDATE=true

SECURITY_UPDATE_VIA_MYORACLESUPPORT=false
—————————————————————————————————————

As a result, I confirmed that the following directories and files were not created:

• $ORACLE_HOME/modules
• $ORACLE_HOME/utils
• $ORACLE_HOME/wlserver/.product.properties

I have three points I would like to confirm regarding the above:

1. I had expected these directories and files to be created after installation. Is it a problem that these directories and files do not exist?
