We followed the instructions in the documentation to install the ODBC software module, the files were never copied to the $ODBC_HOME folder.
Release : 14.5.0
The procedure for installing the ODBC component for Harvest 14.5 has changed. With previous versions you unzipped the odbc.tar.gz into a separate folder location and installed from there into your desired $ODBC_HOME location. With SCM 14.5 you will unzip into your desired $ODBC_HOME location and ensure before executing the install.sh script that $ODBC_HOME and $ORACLE_HOME environment variables are set correctly. The installation documentation for SCM 14.5 has been updated to reflect this change.
