The determination of Oracle binary support for Real Application Clustering is made during installation on all supported platforms. Thus an installation made for a RAC database install will result in errors for single database instances. However, you can modify the binaries to support single instance database features after installation. This article details the steps to modify your Oracle binaries to support Oracle single instance database.

1. Logon to your Oracle database server as the Oracle software owner.

2. Change directory to your ORACLE_HOME/rdbms/lib.

cd $ORACLE_HOME/rdbms/lib

3. Use make to recreate your Oracle binaries with the option rac_off

make -f ins_rdbms.mk rac_off

4. Change directory to your ORACLE_HOME/bin.

5. Execute the utility relink with option all, to recreate all binary files.

relink all

6. This completes altering your Oracle RDBMS binaries to support Oracle RAC features.
