After successfully installing Grid Infrastructure with the “grid” user, I attempted to install Oracle Database 19c Release 3 using the “oracle” user. However, during the installation process, I encountered an issue where none of my ASM (Automatic Storage Management) disks were visible in the disk group selection menu.
Log in as root user
1 2 3 4 5 6 | cd /dev/oracleasm/ls -ltrtchown -R grid:oinstall oracleasmcd /dev/oracleasm/disks |
Login as grid user
1 2 3 4 5 | cd $ORACLE_HOME/binls -ltrhchmod 6571 oraclels -ltrh oracle |
Login as oracle user
1 2 | cd $ORACLE_HOME/binls -ltrh oracle |
To ensure consistency in directory permissions between the “grid” and “oracle” users, execute the following command:
1 | chmod 6571 oracle |
No rerun the runInstaller.sh file , it will show the disk group.
Hope it helped !!
