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=ifscdb
# 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=ifs1db
# export PDB_NAME=ifspdb
# 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
