Installing Instant Client 19.8 on macOS
Instant Client 19.8 supports macOS High Sierra, Mojave, Catalina, and Big Sur.
cd /Volumes/instantclient-basic-macos.x64-19.8.0.0.0dbru
$ ./install_ic.sh
This copies the contents of all currently mounted Instant Client .dmg packages to /User/$USER/Downloads/instantclient_19_8
export PATH=~/Downloads/instantclient_19_8:$PATH
Installing Instant Client 18.1 on macOS
Instant Client 18.1 supports macOS Mojave and High Sierra.
~/instantclient_18_1
that is accessible to your application. For example:
cd ~
unzip instantclient-basic-macos.x64-18.1.0.0.0.zip
~/lib
or /usr/local/lib
to enable applications to find the libraries. For example, OCI based applications could do:
mkdir ~/lib
ln -s ~/instantclient_18_1/libclntsh.dylib ~/lib/
Alternatively, copy the required libraries. For example, to use OCI applications:
mkdir ~/lib
cp /opt/oracle/instantclient_18_1/libclntsh.dylib.18.1 ~/lib/
cp /opt/oracle/instantclient_18_1/libclntshcore.dylib.18.1 ~/lib/
cp /opt/oracle/instantclient_18_1/libons.dylib ~/lib/
cp /opt/oracle/instantclient_18_1/libnnz18.dylib ~/lib/
cp /opt/oracle/instantclient_18_1/libociei.dylib ~/lib/
ln -s ~/lib/libclntsh.dylib.18.1 ~/lib/libclntsh.dylib
Note: Custom OCI applications, such as those that bundle Instant Client, may want to link with -rpath
set to the directory containing Instant Client 18.1 instead of relying on libraries being in ~/lib
.
tnsnames.ora
, sqlnet.ora
, ldap.ora
, or oraaccess.xml
with Instant Client, put them in the instantclient_18_1/network/admin
subdirectory. This is the default Oracle configuration directory for applications linked with this Instant Client.Alternatively, Oracle configuration files can be put in another, accessible directory. Then set the environment variable TNS_ADMIN
to that directory name.
PATH
environment variable, for example: export PATH=~/instantclient_18_1:$PATH
sqlplus hr/welcome@localhost/orclpdb
Installing Instant Client 12.2 on macOS
Instant Client 12.2 supports macOS High Sierra, Sierra and El Capitan.
~/instantclient_12_2
that is accessible to your application. For example:
cd ~
unzip instantclient-basic-macos.x64-12.2.0.1.0.zip
~/lib
or /usr/local/lib
to enable applications to find the libraries. For example, OCI based applications could do:
mkdir ~/lib
ln -s ~/instantclient_12_2/libclntsh.dylib ~/lib/
ln -s ~/instantclient_12_2/libclntsh.dylib.12.1 ~/lib/
Alternatively, copy the required libraries. For example, to use OCI applications:
mkdir ~/lib
cp /opt/oracle/instantclient_12_2/libclntsh.dylib.12.1 ~/lib/
cp /opt/oracle/instantclient_12_2/libclntshcore.dylib.12.1 ~/lib/
cp /opt/oracle/instantclient_12_2/libons.dylib ~/lib/
cp /opt/oracle/instantclient_12_2/libnnz12.dylib ~/lib/
cp /opt/oracle/instantclient_12_2/libociei.dylib ~/lib/
ln -s ~/lib/libclntsh.dylib.12.1 ~/lib/libclntsh.dylib
Note: Custom OCI applications, such as those that bundle Instant Client, may want to link with -rpath
set to the directory containing Instant Client 12.2 instead of relying on libraries being in ~/lib
.
tnsnames.ora
, sqlnet.ora
, ldap.ora
, or oraaccess.xml
with Instant Client, then create a network/admin
subdirectory. For example: mkdir -p ~/instantclient_12_2/network/admin
This is the default Oracle configuration directory for applications linked with this Instant Client.
Alternatively, Oracle configuration files can be put in another, accessible directory. Then set the environment variable TNS_ADMIN
to that directory name.
PATH
environment variable, for example: export PATH=~/instantclient_12_2:$PATH
sqlplus hr/welcome@localhost/orclpdb
Installing Instant Client 12.1 on macOS
Instant Client 12.1 supports macOS El Capitan, Yosemite and Mavericks.
cd ~
unzip instantclient-basic-macos.x64-12.1.0.2.0.zip
cd ~/instantclient_12_1
ln -s libclntsh.dylib.12.1 libclntsh.dylib
OCCI programs will additionally need:
ln -s libocci.dylib.12.1 libocci.dylib
mkdir ~/lib
ln -s ~/instantclient_12_1/libclntsh.dylib ~/lib/
ln -s ~/instantclient_12_1/libclntsh.dylib.12.1 ~/lib/
Alternatively, copy the required libraries. For example, to use OCI applications:
mkdir ~/lib
cp /opt/oracle/instantclient_12_1/libclntsh.dylib.12.1 ~/lib/
cp /opt/oracle/instantclient_12_1/libclntshcore.dylib.12.1 ~/lib/
cp /opt/oracle/instantclient_12_1/libons.dylib ~/lib/
cp /opt/oracle/instantclient_12_1/libnnz12.dylib ~/lib/
cp /opt/oracle/instantclient_12_1/libociei.dylib ~/lib/
Note: Custom OCI applications, such as those that bundle Instant Client, may want to link with -rpath

Installing Instant Client 11.2 on macOS
Instant Client 11.2 supports macOS X Lion, Mountain Lion and Mavericks.
cd ~
unzip instantclient-basic-macos.x64-11.2.0.4.0.zip
unzip instantclient-sqlplus-macos.x64-11.2.0.4.0.zip
cd ~/instantclient_11_2
ln -s libclntsh.dylib.11.1 libclntsh.dylib
Note: OCCI programs will additionally need:

mkdir ~/lib
ln -s ~/instantclient_11_2/{libclntsh.dylib.11.1,libnnz11.dylib,\
