It verifiesthe network configuration of the server, verifies and unzips the installation media,verifies the cell.conf file, and verifies that all parameter and deployment files canbe found in the onecommand directory.Creates SSH keys for the root account on all compute nodes and storage cells fortrusted SSH authentication.Validates the cell.conf file on all compute nodes and storage servers and verifiesthat all storage cells are installed with the same version of cell software.Unzips the DBMS, Grid Infrastructure, and bundle patch files.Updates the /etc/hosts files.Creates the cellip.ora file on the compute nodes, and the cellinit.ora file on thestorage cells.Validates the hardware on all servers and cells using the CheckHWnFWProfilecommand.Verifies the InfiniBand network.Validates the storage cells by running various CellCLI commands. For example:cellcli -e list physicaldiskChecks RDS using the /usr/bin/rds-ping command.Check cell disks using the CellCLI calibrate command. This command tests theperformance characteristics of your cell disks.Validates the date, time, and NTP synchronization across all computed nodes andstorage cells. The NTP service is started if necessary.Updates the following files on the database servers, adding settings typical for anOracle database server environment:/etc/security/limits.conf/etc/profile264
