Backup doubt

[gnagesh]

Hi

I have got some doubt. Your inputs highly appreciated.

Assume my database is running in ARCHIVE LOG MODE and I perform hot backup

ALTER TABLESPACE BEGIN BACKUP.... END BACKUP...blabla...

And I performed RMAN backup using

run {
allocate channel d1 type disk;
backup
filesperset 5
format '/u06/oradata/rmanbackups/df_%d_%s_%p'
(database include current controlfile);
release channel d1;
allocate channel d1 type disk;
backup
format '/u06/oradata/rmanbackups/al_%d_%s_%p'
(archivelog all delete input);
release channel d1;
}

Now doubt is Is the above RMAN backup procedure is the same as hotbackup procedure in terms of result while recovery? Or any diffrences? or any thing I am missing in above RMAN backup procedure?

Do I need to add ALTER SYSTEM SWITCH LOGFILE?

Thanks In Advance

Yes, you do need to force log switch, otherwise your last online redo log will not be backed up. I do not see any difference in terms of recovery. However, how big is a file generated by rman? If it bigger than 2gb , do your have OS issues related to the size?
