Hi All, Good morning. While running root.sh as root during binary installation (any version), the questions below come up. What is the importance of /usr/local/bin? My understanding is that the value should be the $ORACLE_HOME/bin instead of /usr/local/bin. Am I right? When there are many ORACLE_HOME with different versions(lets say 9i, 10g and 11g), what impact does it have on the setting of local bin directory location? Ideally speaking, do I have to set them to their respective $ORACLE_HOME/bin ? Many Thanks for your help. # /opt/oracle/products/9208/root.sh Running Oracle9 root.sh script... The following environment variables are set as: ORACLE_OWNER= oracle ORACLE_HOME= /opt/oracle/products/9208 Enter the full pathname of the local bin directory: [/usr/local/bin]: The file "dbhome" already exists in /usr/local/bin.
