Which three actions are performed by the Oracle Preinstallation RPM, oracle-database-server-xxxx-preinstall, for Oracle Grid Infrastructure, where xxxx is the Oracle version and release? (Choose three.)
Which three actions are performed by the Oracle Preinstallation RPM, oracle-database-server-xxxx-preinstall, for Oracle Grid Infrastructure, where xxxx is the Oracle version and release? (Choose three.)
The Oracle Preinstallation RPM performs several key actions to prepare the system for Oracle Grid Infrastructure installation. It creates the oracle OS user, which is necessary for running Oracle software. It also creates the OSDBA (dba) group, which is required for database administration privileges, and the oraInventory (oinstall) group, which is used to manage Oracle software installations. These three actions are essential steps carried out by the Oracle Preinstallation RPM to ensure the system is properly configured for Oracle Grid Infrastructure.
correct = BCD
janW You are right the answer is BCD.
When installed, the Oracle Preinstallation RPM does the following: Automatically downloads and installs any additional RPM packages needed for installing Oracle Grid Infrastructure and Oracle Database, and resolves any dependencies Creates an oracle user, and creates the oraInventory (oinstall) and OSDBA (dba) groups for that user As needed, sets sysctl.conf settings, system startup parameters, and driver parameters to values based on recommendations from the Oracle Preinstallation RPM program Sets hard and soft resource limits Sets other recommended parameters, depending on your kernel version Sets numa=off in the kernel for Linux x86_64 machines.
Correct: B,C,D When installed, the Oracle Database Preinstallation RPM does the following: -Automatically downloads and installs any additional RPM packages needed for installing Oracle Grid Infrastructure and Oracle Database, and resolves any dependencies -Creates an oracle user, and creates the oraInventory (oinstall) and OSDBA (dba) groups for that user -As needed, sets sysctl.conf settings, system startup parameters, and driver parameters to values based on recommendations from the Oracle Database Preinstallation RPM program -Sets hard and soft resource limits -Sets other recommended parameters, depending on your kernel version -Sets numa=off in the kernel for Linux x86_64 machines. https://docs.oracle.com/en/database/oracle/oracle-database/19/ladbi/about-the-oracle-preinstallation-rpm.html
B,C,D - from here https://docs.oracle.com/cd/E11882_01/install.112/e41961/prelinux.htm#CWLIN172
100% BCD
I agree that B, C, D are correct, but what is wrong with A?
I think that one will be run during the Grid installation prereq check.
The answer is B,D,C. F is incorrect.
BCD, Automatically downloads and installs any additional RPM packages needed for installing Oracle Grid Infrastructure and Oracle Database, and resolves any dependencies. Creates an oracle user, and creates the oraInventory ( oinstall ) and OSDBA ( dba ) groups for that user. As needed, sets sysctl. https://docs.oracle.com/en/database/oracle/oracle-database/18/cwlin/about-the-oracle-preinstallation-rpm.html#GUID-C15A642B-534D-4E4A-BDE8-6DC7772AA9C8
I am really disappointed by the answer given for this unless the question mixed grid and database install.. the correct answer is Oracle user, OS Group, and OraInventory
The RPM does not configure the system

Correct BCD, https://docs.oracle.com/en/database/oracle/oracle-database/18/ladbi/about-the-oracle-preinstallation-rpm.html#GUID-C15A642B-534D-4E4A-BDE8-6DC7772AA9C8

BCD is correct
Pls help. For B, what is meant by 'creating "the" oracle OS user?' I have doubt why B is correct and F is incorrect. https://docs.oracle.com/en/database/oracle/oracle-database/12.2/ladbi/overview-of-oracle-linux-configuration-with-oracle-rpms.html#GUID-693599D4-BD32-4E6A-9689-FA7D1CD75653 Configuring a server using Oracle Linux and the Oracle Preinstallation RPM consists of the following steps: 1. Install Oracle Linux. 2. Register your Linux distribution with Oracle Unbreakable Linux Network (ULN) or download and configure the yum repository for your system using the Oracle Linux yum server for your Oracle Linux release. 3. Install the Oracle Preinstallation RPM with the RPM for your Oracle Grid Infrastructure and Oracle Database releases, and update your Linux release. 4. Create role-allocated groups and users with identical names and ID numbers. 5. Complete network interface configuration for each cluster node candidate. 6. Complete system configuration for shared storage access as required for each standard or Core node cluster candidate.
