Update script for installing oracle instantclient
The script installOracle21.sh
currently performs a wget
to https://download.oracle.com/otn_software/linux/instantclient/2112000/el9/oracle-instantclient-basic-21.12.0.0.0-1.el9.x86_64.rpm
whereas the (more recent) RPMs are also available at https://yum.oracle.com/repo/OracleLinux/OL9/oracle/instantclient23/x86_64/index.html
. This should be updated.
