Overview of the Database Conversion Process Using rconfig

The following list provides an outline of the process of converting a single-instance database to an Oracle RAC database using the rconfig utility:

• Complete the prerequisite tasks for converting to an Oracle RAC database.

  • Oracle Clusterware and Oracle Database software is installed on all target nodes.

  • Oracle Clusterware is started.

  • The Oracle Database binary is enabled for Oracle RAC on all target nodes.

  • Shared storage is configured and accessible from all nodes.

  • User equivalency is configured for the operating system user performing the conversion.

  • The database being converted has been backed up successfully.

• Modify the parameters in the Oracle_home/assistants/rconfig/sampleXMLs/ConvertToRAC.xml file as appropriate for your environment, then save the file.

• Run the rconfig command, supplying the name of the modified ConvertToRAC.xml file as input.

• Complete the post-conversion tasks.

You can also use the rconfig utility to convert single-instance ASM to clustered ASM.
