if you are used to use silent installation for the oracle database software you need to provide additional parameters: oracle.install.db.BACKUPDBA_GROUP, oracle.install.db.DGDBA_GROUP and oracle.install.db.KMDBA_GROUP
./runInstaller oracle.install.option=INSTALL_DB_SWONLY \ ORACLE_BASE=/opt/oracle/product/base \ ORACLE_HOME=/opt/oracle/product/base/184.108.40.206 \ UNIX_GROUP_NAME=oinstall \ oracle.install.db.DBA_GROUP=dba \ oracle.install.db.OPER_GROUP=oper \ oracle.install.db.BACKUPDBA_GROUP=dba \ oracle.install.db.DGDBA_GROUP=dba \ oracle.install.db.KMDBA_GROUP=dba \ FROM_LOCATION=../stage/products.xml \ INVENTORY_LOCATION=/opt/oracle/oraIventory \ SELECTED_LANGUAGES=en \ oracle.install.db.InstallEdition=EE \ DECLINE_SECURITY_UPDATES=true -silent -ignoreSysPrereqs -ignorePrereq -waitForCompletion
otherwise your installation will fail with:
[FATAL] [INS-35341] The installation user is not a member of the following groups: [null, null, null] CAUSE: The installation user account must be a member of all groups required for installation. ACTION: Ensure that the installation user is a member of the system privileges operating system groups you selected.
these are used to further improve seperation of duties: documentation
