Oracle Environment Variables

Some environment variables must be configured on the server to install and run Oracle Database 19c.

Note: If ORACLE_BASE is used, Oracle recommends not to set the ORACLE_HOME environment variable but that you choose the default path suggested by the Universal Installer. When you have finished the installation of Oracle Database 19c, you can set the ORACLE_HOME environment variable.

Following Oracle environment variables must be set or updated for the Oracle user.

• TMP
• TMPDIR
• ORACLE_HOSTNAME
• ORACLE_UNQNAME
• ORACLE_BASE
• ORACLE_HOME
• ORA_INVENTORY
• ORACLE_SID
• PDB_NAME
• DATA_DIR
• PATH
• LD_LIBRARY_PATH
• CLASSPATH

The oracle user's .bash_profile file can be updated using following commands:

# su – oracle
# cat >> .bash_profile << EOF
# export TMP=/tmp
# export TMPDIR=\$TMP
# export ORACLE_HOSTNAME=<YOUR_HOST>.localdomain
# export ORACLE_UNQNAME=ifs10cdb
# export ORACLE_BASE=/u01/app/oracle
# export ORACLE_HOME=\$ORACLE_BASE/product/19.0.0/dbhome_1
# export ORA_INVENTORY=/u01/app/oraInventory
# export ORACLE_SID=ifs10cdb
# export PDB_NAME=ifs10pdb
# export DATA_DIR=/u02/oradata
# export PATH=/usr/sbin:/usr/local/bin:\$PATH
# export PATH=\$ORACLE_HOME/bin:\$PATH
# export LD_LIBRARY_PATH=\$ORACLE_HOME/lib:/lib:/usr/lib
# export CLASSPATH=\$ORACLE_HOME/jlib:\$ORACLE_HOME/rdbms/jlib
# EOF
