I am using home grown scripts and they work.  I have Legato use savepnpc (pre/post proc) command call this script:



//begin snippet comment section



#!/bin/ksh

#######################################################

# $ORABIN/db_hot_backup.ksh

#######################################################

#

# Common script used to alter one database or all databases

# on this server for hot backup mode (begin/end).

# This script does NOT actually copy database files to disk

# or to tape.

#

# Hot Backup Algorithm listed below:

#       1) Alter system archive log current ;

#       2) Check backup status.

#       3) Generate datafile listing.

#       4) Alter tablespace <tablespace_name> begin backup ;

#       5) Some other process,script,legato,etc. will copy database files

#          to disk or to tape.

#       6) Alter tablespace <tablespace_name> end backup ;

#       7) Alter system archive log current ;

#       8) Backup controlfile.

#       9) Alter system archive log current ;

hth,

PS. I have tested recoveries and they worked, but soon my scripts will succumb to RMAN :).

  I was thinking of simply copying the datafiles using the OS facilities.
If you are putting hot backups to tape directly I am not sure that they will
be usable for recovery.  RMAN requires a third party media manager to handle
backups to tape. If rman can't do it, I am not sure that homegrown scripts
can either.
