Hi All,

I am new to RMAN. I am reading RMAN documentation and doing some testing on our development box.

I have couple of questions.

1. Our database is in NOARCHIVE LOG mode and I would like to do Incremental backups. Since db is in noarchive log mode, I put the database in mount state and did the base level and incremental backups. Looks like it worked fine.

     In one of the training documentation, it says 'Because the database is in noarchive log mode, the incrementals are

     not applicable, so use the full backup option'.

     It is contrary to what I did. Am I missing something here. please clarify me. Are the backups valid?

2. Since the database is in noarchive log mode, db is in mount state during full/incremental backup.

     I want to keep the database open if possible and would like to know if the following procedure works to

    keep the database open during the backup.

1. Shutdown the db before backup.
2. Bring back the db in ARCHIVE LOG mode.
3. Perform full/incremental backups (including archive log files) while the database is open.
4. Shutdown the db after backup is done.
5. Bring back the db in NOARCHIVE LOG mode.

   I am not sure whether it makes sense or not. Please pass your suggestions.

Thanks in advance for your suggestions.
Best regards,
Prasad
