That's weird, it works fine for me with 5.1 MP4 on AIX - I ran the following successfully just last month: rman target sys/pwd@baanprd <mailto:sys/pwd@baanprd> catalog rman/pwd@rcat <mailto:rman/pwd@rcat> auxiliary / msglog $RESTORE_LOG append <<EOF run{ allocate auxiliary channel ch1 type 'SBT_TAPE' parms 'ENV=(NB_ORA_CLIENT=baanprd01)'; duplicate target database to baantst; } EOF So it sounds like the problem was either introduced in MP5, or is specific to Windows, or maybe is only a problem when sending multiple parameters? Anyway, I'll keep an eye out for it if we have difficulty with DUPLICATE DATABASE in the future.
