Installation directory

Starting with SQL/R A.04.00, multiple SQL/R versions may be installed and used in parallel. Each major version is installed into a separate directory while minor updates will update an existing version. SQL/R A.04.20 is installed in the 4.2 subdirectory.

The installation procedure retains the configuration of a previous SQL/R release. Modified configuration files are retained and not deleted when uninstalled.

Linux and HP-UX

The SQL/R A.04.20 software is installed in the /opt/sqlr/4.2 directory, configuration files are in /etc/opt/sqlr/4.2.

When updating from a previous SQL/R version, any configuration files need to be copied manually. A symlink may also be used as configuration files are fully upwards compatible.

Please note: Previous SQL/R versions before A.04.00 created a symlink /opt/sqlr to point to /opt/sqlr2. This symlink is removed during the installation.

Windows

By default, SQL/R A.04.20 is installed in the "Program Files\Marxmeier\SQLR\4.2" directory.

The Windows installation program has the option to migrate the previous configuration files and/or remove the previous SQL/R version.

License keys

SQL/R A.04.20 requires a license key version A.04.20 or above. A previous license key for an older version does no longer work.

A license key must be obtained to use the SQL/R server components. No license key is required to use the ODBC Driver to connect to another server system.
