Hello, I have been redaing some about the switchover and failover techniques. Most of what I've found has been how to do it manually or using command-line. Can someone help with the info, links, documents on how to perform sitchover + failover using OEM DGM. And also, if I undersdtand the process right, after the failover is done, the primary db has to be rebuilt. What's the procedure to rebuilt it and swicth back to the original db: so that after the failover, you rebuild the ex-primary, then switch back to it, making the new primary as standby.
