Install Oracle Machine Learning for R in an Oracle 23ai RAC Environment

Following these step to install Oracle R Distribution, Oracle Machine Learning for R, and the Oracle Machine Learning for R supporting packages.

1. Install Oracle R Distribution. See Install R for Oracle Machine Learning for R on On-Premises Oracle AI Database.
2. Start SQL*Plus, log in to your PDB directly and run the rqcfg.sql script. The following example uses the PDB PDB1 and gives example values for the script arguments.

   SQL> sqlplus / as sysdba
   SQL> alter session set container=PDB1;
   SQL> ALTER PROFILE DEFAULT LIMIT PASSWORD_VERIFY_FUNCTION NULL;
   SQL> @$ORACLE_HOME/R/server/rqcfg.sql
   
   define permtbl = SYSAUX
   define temptbl = TEMP
   define orahome = /u01/app/oracle/product/23.4.0.0/dbhome_1
   define rhome = /usr/lib64/R

3. At your operating system prompt, go to the ORACLE_HOME/bin directory and grant read and run permission to all users to the ORE directory.

   cd  $ORACLE_HOME/bin
   chmod 755 ORE

4. Create a directory to contain the Oracle Machine Learning for R 2.0 supporting packages for your system and change directories to it. To that directory, download the supporting package zip file as described in Install the Oracle Machine Learning for R Supporting Packages.
5. Extract the supporting packages.
6. For each package, at your operating system command prompt, run the following command.

   ORE CMD INSTALL package
