Retention policy in RMAN

I have several Oracle 8i and Oracle 10g database instances on a Windows 2003 server. We use RMAN backups on these servers. Oracle 9i has the CONFIGURE RETENTION POLICY TO RECOVERY WINDOWS OF 7 DAYS parameter. What parameter can I use on the Oracle 8i database to keep only seven days of backup files on disk?

My question concerns the retention policy of RMAN on Oracle 8i and 10g. I have several Oracle 8i and Oracle 10g database instances on a Windows 2003 server. We use RMAN backups on these servers. We run a batch job daily to perform database backups. We create RMAN level 0 on Sunday, level 1 on Thursday, and Tuesday, Thursday, Friday and Saturday we do level 2 backups. I would like to keep the backup files for seven days. Oracle 9i has the CONFIGURE RETENTION POLICY TO RECOVERY WINDOWS OF 7 DAYS parameter. What parameter can I use on the Oracle 8i database to keep only seven days of backup files on disk? Thank you.
The RECOVERY WINDOW option of RMAN is a feature new to Oracle 9i databases. And this feature is available in Oracle 10g as well. Unfortunately, there is no equivalent feature in Oracle 8i.
