Thanks a lot. I know in Oracle 8.1.7, RMAN added explict command for creating standby database
control file, but duplicate command is available in 8.1.6.

If I duplicate database (is n't database identical to production) and then use standby database control file using Oracle';s datbase comand (Instead of RMAN command), won't that work. I am just trying to undesratnd what is
in duplicate command which is different from shutting down database and then making OS backup and
sending it to standby site. Oracle allows a cold or hot backup to set initial standby database, as long as all the arcived logs for recpvery are copied/

If RMAN's duplicate command does not work, I have another option to use Netbackup's alternate retsore which restores database on a different server (than where the backup was done) and then use it. I can then create a tandby controlfile on primary and then copy it.
