Convert non-RAC database to RAC database using rconfig

In $ORACLE_HOME/assistants/rconfig/sampleXMLs directory, there are two templates ConvertToRAC_AdminManaged.xml and ConvertToRAC_PolicyManaged.xml that are used to convert a single instance database to RAC admin managed or policy managed database respectively.

In this article we will convert the single instance database to an admin managed RAC database.

Source Server:

$ORACLE_HOME/assistants/rconfig/sampleXMLs


Change the following parameters according to your environment


Convert verify="ONLY">
<SourceDBHome>/ora/oracle/oracle12/product/12.1.0/dbhome_12</n:SourceDBHome>
<TargetDBHome>/ora/oracle/product/12.1.0/dbhome_1</n:TargetDBHome>
 <SourceDBInfo SID="oratech">
 <Password>afi123</n:Password>
 <Node name="rac01"/>
 <Node name="rac02"/>
 <InstancePrefix>oratech</n:InstancePrefix>
  <SharedStorage type="ASM">
  <TargetFlashRecoveryArea>+DATA</n:TargetFlashRecoveryArea>
