I am trying to duplicate via RMAN a two node OPS database to a single node instance. The datafiles copy correctly and the archive logs from the node where the backup was performed (lets say node A) restore but RMAN fails when trying to locate the next archive log that is not in the backup set but in a Archive logs back from the other node(node B). In the below example oprdb02 is the node the backups were taken from.

RMAN file is as follows:
run {
allocate auxiliary channel ch1 type 'sbt_tape'
parms="ENV=(NB_ORA_SERV=alex, NB_ORA_CLIENT=oprdb021000)";
set autolocate on;
set until logseq 2531 thread 1;
set archivelog destination to '/oprsand01/orarch01/DUP/';
duplicate target database to OPRWS

Anyone done this sucessfully? If so could i see a copy of your config file?
