RMAN duplicate not restore to the latest incremental backupset

   Hi,

Below are my database specs:

OS: RHEL AS 5.3

DB: 11.1.0.7.0.

I try to perform RMAN duplicate to restore a standby database, but the duplication only taking the latest level 0 backup and it is not picking up the latest incremental level 1 backup.

Below commands i have issue in the standby host:

rman target sys/password@ebeandb catalog rman/password@catdb auxiliary /
