ODBC users should follow the ODBC Installation Instructions.
Client-server version interoperability is detailed in Doc ID 207303.1. For example, Oracle Call Interface 19.3 can connect to Oracle Database 11.2 or later. Some tools may have other restrictions.
Installation of ZIP files:
/opt/oracle/instantclient_19_3 that is accessible to your application. For example:
cd /opt/oracle
unzip instantclient-basic-linux-19.3.0.0.0dbru.zip
cd /opt/oracle/instantclient_12_2
ln -s libclntsh.so.12.1 libclntsh.so
ln -s libocci.so.12.1 libocci.so
libaio package. This is called libaio1 on some Linux distributions.For example, on Oracle Linux, run:
sudo yum install libaio
sudo sh -c "echo /opt/oracle/instantclient_19_3 > \
/etc/ld.so.conf.d/oracle-instantclient.conf"
sudo ldconfig
Alternatively, set the LD_LIBRARY_PATH environment variable prior to running applications. For example:
export LD_LIBRARY_PATH=/opt/oracle/instantclient_19_3:$LD_LIBRARY_PATH
The variable can optionally be added to configuration files such as ~/.bash_profile and to application configuration files such as /etc/sysconfig/httpd.
tnsnames.ora, sqlnet.ora, ldap.ora, or oraaccess.xml with Instant Client, then create a network/admin subdirectory. This needs to be created for 12.2 and earlier, for example: mkdir -p /opt/oracle/instantclient_12_2/network/admin
This is the default Oracle configuration directory for applications linked with this Instant Client.
Alternatively, Oracle configuration files can be put in another, accessible directory. Then set the environment variable TNS_ADMIN to that directory name.
PATH environment variable, for example: export PATH=/opt/oracle/instantclient_19_3:$PATH
Installation of RPM files:
yum. For example: sudo yum oracle-instantclient19.3-basic-19.3.0.0.0-1.i386.rpm
Note that from 19.3, by default only one version of the Instant Client RPM libraries can be installed at a time.
sudo sh -c "echo /usr/lib/oracle/18.3/client/lib > \
/etc/ld.so.conf.d/oracle-instantclient.conf"
sudo ldconfig
For Instant Client 19.3 RPM packages, these commands are automatically run.
Alternatively, set the LD_LIBRARY_PATH environment variable prior to running applications. For example:
export LD_LIBRARY_PATH=/usr/lib/oracle/18.3/client/lib:$LD_LIBRARY_PATH
The variable can optionally be added to configuration files such as ~/.bash_profile and to application configuration files such as /etc/sysconfig/httpd.
tnsnames.ora, sqlnet.ora ldap.ora, or oraaccess.xml with Instant Client, then create a network/admin subdirectory under lib/. This needs to be created for 12.2 and earlier, for example: sudo mkdir -p /usr/lib/oracle/12.2/client/lib/network/admin
This is the default Oracle configuration directory for applications linked with this Instant Client.
Alternatively, Oracle configuration files can be put in another, accessible directory. Then set the environment variable TNS_ADMIN to that directory name.
yum to install the package and then update your PATH environment variable, for example: export PATH=/usr/lib/oracle/19.3/client/bin:$PATH
