Hello;
No.
If you create the SRL on the Primary and then take an RMAN backup for duplicate they will be part of that backup.
Example :
RMAN RUN {
allocate channel d1 type disk;
backup format '/u01/backups/PRIMARY/df_t%t_s%s_p%p' database;
sql 'alter system archive log current';
backup format '/u01/backups/PRIMARY/al_t%t_s%s_p%p' archivelog all;
backup current controlfile for standby format '/u01/backups/PRIMARY/sb_t%t_s%s_p%p';
release channel d1;
}Restore example
run {
allocate channel C1 device type disk;
allocate auxiliary channel C2 device type disk;
duplicate target database for standby nofilenamecheck;
}Best Regards

Double Check ( To be clear on Oracle 11, but I think it work the same on 10 )
I checked my test Standby which I created using RMAN- The SRL's are there.
But you are 10 so use this to check for them :
select * from v$standby_log;If they are not there and the database is mounted create them as follows :
ALTER DATABASE ADD STANDBY LOGFILE GROUP 4 '/u01/app/oracle/oradata/PRIMARY/redo04.log' SIZE 100M;Change path, size, names and groups as needed.
