The Oracle RAC Configuration section has the following fields.

Connection String

Enter the description portion of the RAC definition in the tnsnames.ora file. This file is located in the \network\admin\ folder where Oracle is installed. Locate the description, which looks similar to this example:

	RAC=(description=
		(address_list=
			(load_balance=on)
			(failover=on)
			(address=(protocol=tcp)(host=2k3rac2-vip)(port=1521)))
			(connect_data=(service_name=kfsrac)
		)
	)

Copy the description for your RAC and paste it into the field. If you are typing the string manually, remove line breaks and extra spaces, as in this example:

(description=(address_list=(load_balance=on)(failover=on)(address=(protocol=tcp)(host=2k3rac1-vip)(port=1521))(address=(protocol=tcp)(host=2k3rac2-vip)(port=1521)))(connect_data=(service_name=kfsrac)))
