HP 3PAR Application Software Suite for Oracle - Manual (Page 11)

When creating an online virtual copy, the create utility performs the following actions:
•
Discovers devices (3PAR virtual volumes) used by the datafiles and archive log destination.
•
Puts the database in backup mode.
•
Creates a virtual copy for the datafile virtual volumes.
•
Takes the database out of backup mode.
•
Switches online redo logs and archives them to archive log destination.
•
Resynchronizes the Recovery Catalog to update with newly generated archive logs if the virtual
copy is to be backed up using Oracle RMAN.
•
Creates a virtual copy for the archive log destination virtual volumes.
A datafile virtual copy is created while the database is OPEN. The create utility performs the
following actions:
•
Discovers devices (3PAR virtual volumes) used by the datafiles.
•
Puts the database in backup mode.
•
Creates a virtual copy for the datafile virtual volumes.
•
Takes the database out of backup mode.
An offline virtual copy is created while the database is CLOSED. The create utility performs the
following actions:
•
Starts up the database in MOUNTED mode to retrieve a list of datafiles and shuts down the
database.
•
Discovers devices (3PAR virtual volumes) used by the datafiles.
•
Creates a virtual copy for the datafile virtual volumes.
An archive log virtual copy is created while the database is OPEN and performs the following
actions:
•
Discovers devices (3PAR virtual volumes) used by the archive log destination.
•
Switches logs and archives online redo logs to archive log destination.
•
Resynchronizes the Recovery Catalog to update with newly generated archive logs if the virtual
copy is to be backed up using Oracle RMAN.
•
Creates a virtual copy for the archive log destination virtual volumes.
NOTE: If the virtual copy is to be backed up using Oracle RMAN, a Recovery Catalog must have
been created and configured prior to running this utility. For an RAC database, archive log
destinations of all RAC instances must be on shared storage (same cluster file systems or same
ASM disk groups).
The Virtual Copy Display Utility
HP 3PAR Recovery Manager Software for Oracle’s display utility (rmora_display) displays
database virtual copies along with other information including creation time, type, status, and
backup status. For systems running InForm OS 2.3.1 and above, the rmora_display utility also
provides the option to display a virtual copy's retention and expiration times.
A virtual copy's type can be either Online, Offline, Datafile, or Archlog.
•
An Online virtual copy indicates that the virtual copy for the database was created while it
was OPEN (online).
•
An Offline virtual copy indicates that the virtual copy for the database was created while it
was CLOSED (offline).
