4.3.1 Prepare to Use Oracle Machine Learning for R Server with R-4.4.1 or Later

Instructions for downloading and installing the Oracle Machine Learning for R Server packages built under R-4.4.1.

In Oracle AI Database 23.7, the OML4R Server packages are shipped in the $ORACLE_HOME/R/library/ directory. If you are using R-4.4.1, you can either rename or delete the existing OML4R packages in that directory. Afterward, download and install the OML4R Server packages that are compatible with your R version.

These instructions rename the original OML4R Server packages and replace them with versions built using R-4.4.1.

  1. Rename the OML4R packages in the $ORACLE_HOME/R/library/ directory:
    cd $ORACLE_HOME/R/library

mv ORE ORE.orig
mv OREbase OREbase.orig
mv OREcommon OREcommon.orig
mv OREdm OREdm.orig
mv OREdplyr OREdplyr.orig
mv OREeda OREeda.orig
mv OREembed OREembed.orig
mv OREgraphics OREgraphics.orig
mv OREmodels OREmodels.orig
mv OREpredict OREpredict.orig
mv OREserver OREserver.orig
mv OREstats OREstats.orig
mv ORExml ORExml.orig
  2. Go to the Oracle Machine Learning for R Downloads page, accept the license agreement, and download the R-4.4.1 compatible OML4R Server and Supporting packages to an installation directory, such as /oml4rserver_install_dir/.

    Note:

    Use the same installation directory for all OML4R components.
  3. Go to the installation directory and unzip the downloaded file.
    $ cd /oml4rserver_install_dir/
$ unzip oml4r-server-r4.4.1-linux8-x86-64-2.0.zip
$ unzip oml4r-supporting-r4.4.1-linux8-x86-64-2.0.zip

    When you unzip the file, the /server directory is created, and the following files are extracted into it: 

    $ ls server

Note:

If you have not installed OML4R 2.0 before, follow the steps in the section Install OML4R Server Using server.sh.

If you already have the OML4R 2.0 server (based on R 4.0.5) installed and want to upgrade to use R 4.4.1, you only need to install the OML4R 2.0 packages, libraries and supporting packages compatible with R 4.4.1, follow the steps in the section, Install OML4R 2.0 Packages and Supporting Packages on the OML4R Server.
