RMAN-05001 auxiliary filename string conflicts with a file used by the target database

If this error message is being returned during RMANDUPLICATE DATABASE command, it is because RMAN would try to created destination files at the same location where source database files exist; and since it cannot overwrite existing files, so it and returns error message.

If Primary database alert log is showing error message similar to the following,

PING[ARC1]: Heartbeat failed to connect to standby 'standby-db'. Error is 16058.

it means that primary database is not able to ship redo log data to
