RMAN Active duplication using SPFILE

Question

Environment:
O.S Version     HP-UX B.11.31 U ia64
Oracle DB Version     11.2.0.3.0
     Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
Database files are on ASM Diskgroups
duplicate target database
to TestDB
from active database pfile=/app/oracle/product/11.2.0.3/db/dbs/initSoruceDB.ora;Question:
Can I use spfile clause on the command above? If I use spfile, will the command above copy the spfile from the target database instance as part of DUPLICATE command?
Will the DUPLICATE command with SPFILE clause behave differently in case of different sturcture of ASM Diskgroups used at the source and target databases?

Answer 1

Can I use spfile clause on the command above? If I use spfile, will the command above copy the spfile from the target database instance as part of DUPLICATE command? Yes you can use SPFILE.RMAN automatically copies the server parameter file to the destination host.
Will the DUPLICATE command with SPFILE clause behave differently in case of different sturcture of ASM Diskgroups used at the source and target databases? RMAN automatically copies the server parameter file to the destination host and updates the server parameter file on the destination host based on values provided in PARAMETER_VALUE_CONVERT and SET. For example:
Duplicating to a Host with a Different Directory Structure (Active)
DUPLICATE TARGET DATABASE
TO dupdb
FROM ACTIVE DATABASE
DB_FILE_NAME_CONVERT '/oracle/oradata/prod/','/scratch/oracle/oradata/dupdb/'
SPFILE
PARAMETER_VALUE_CONVERT '/oracle/oradata/prod/',
'/scratch/oracle/oradata/dupdb/'
SET SGA_MAX_SIZE '300M'
SET SGA_TARGET '250M'
SET LOG_FILE_NAME_CONVERT '/oracle/oradata/prod/redo/',
'/scratch/oracle/oradata/dupdb/redo/';
