I have a scenario where in I need to create a standby database from an existing standby database.
Database version is 11.2.0.2.0 on Linux. I'm looking for RMAN duplicate "from active database" to create the new standby. But the duplicate fails with the below error.
Starting backup at 14-AUG-15
using channel ORA_DISK_1
channel ORA_DISK_1: starting datafile copy
copying standby control file
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

RMAN-03009: failure of backup command on ORA_DISK_1 channel at 14/08/2015 10:13:31
ORA-01671: control file is a backup, cannot make a standby control file
Does anyone has an idea on this ?
