The path environment variable in a Oracle Database context.
The directory that contains the oraenv, coraenv, and dbhome scripts is called the local bin directory.
All database users must have read access to this directory. Include the path of the local bin directory PATH environment variable setting for the users.
When you run the root.sh script after installation, the script prompts you for the path of the local bin directory and automatically copies the oraenv, coraenv, and dbhome scripts to the directory that you specify. The default local bin directory is /usr/local/bin. If you do not run the root.sh script, then you can manually copy the oraenv or coraenv and dbhome scripts from the ORACLE_HOME/bin directory to the local bin directory.
