So to prevent above message from appearing, disable fast-start failover first, remove the target configuration and then the database can be removed from the configuration. If you do not, the following message will DGMGRL tell you: вЂњError: ORA-16867: cannot remove a database that is specified in a FastStartFailoverTarget configuration propertyвЂќ To resolve this issue, copy the password file again to ASM but add the argument вЂњformat=12вЂќ to orapwd, now the redo apply should be able to start.ДЄnother issue can arise where order is important: Before you can remove a database from a Dataguard configuration it should not be a part of a fast-start failover configuration.

ORACLE DATABASE MIGRATION INSTALL

Install and configure the cluster software, and install the database software.Create/provision/have someone build your new infrastructure in the new datacenter.Stop database and cluster(ware) on the standby database cluster and shutdown the machines.If not done already, save relevant listener.ora and tnsnames.ora files.Disable fast-start failover and remove the standby database from dataguard configuration.The application is able to connect to both RAC clusters, and has a sane connect timeout setting (!) in its connection details, so the absense of a cluster for a while should not give a problem. WeвЂ™ve choosen this option to prevent too much configuration work at the application side. It requires of course that the old machines are turned off before starting the installation. Fortunately the environment was already as HA as it could be, by using Dataguard, so migration was nothing more than doing switchovers and duplicating databases.ДЄs the networks in both old and new datacenters were interconnected, same subnet, same broadcast domain, the newly installed machines could use the same name and IP adresses as their old counterparts. My customer needed to migrate to a new set of datacenters, and while other services were able to вЂњlift and shiftвЂќ, the Oracle RAC database servers had to be rebuilt in the new datacenter because the underlying platform wasnвЂ™t able to migrate the shared disks.
