restore with onbar and bcv: How to apply logs

Hello, I have a problem with an EMC Timefinder restore. We have a production database running on EMC storage. To make a backup, i establish a bcv, put the database to archive mode with "onmode -c block", split the bcv an resume the production. Then i import the data from the bcv on a different server ( the netbackup machine ), start the database and backup it to tape with onbar. Works fine. Now I want to restore the database. On the backup server, i can restore the database to the state it was in when i split the bcv. But from this time, production has continued to produce logs ( and write these to tape ). How can i apply these logs ? I thought about merging the data from the ixbar files from production ( for the logs ) and from the backup server ( for the tablespace backups ). Is this legal ? Thanks in advance Max Thoran
