ozo's syntax is correct
your syntax has cp run only 15 min after every hour, not every 15 min

On some systems you need to use the full path name for the command used:

*/15 * * * * /usr/bin/cp /data/BB60/control01.ctl /rman/standby/control01.ctl >> /tmp/mycron.log 2&>1

You should have the option to increase points. You could ask for administrator help
