HP 3PAR Application Software Suite for Oracle - Manual (Page 12)

An archive log Virtual Copy is created while the database is OPEN and performs the following
actions:
•
Discovers devices (HP 3PAR virtual volumes) used by the archive log destination.
•
Switches logs and archives online redo logs to archive log destination.
•
Re-synchronizes 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 be
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
The Virtual Copy utility (rmora_display) of HP 3PAR Recovery Manager Software for Oracle
displays database Virtual Copies along with other information including creation time, type, status,
and backup status. For systems running HP 3PAR OS 2.3.1 and later, the rmora_display utility
also provides the option to display the retention times and expiration times of the Virtual Copy.
A type of Virtual Copy can be either Online, Offline, Datafile, or Archlog.
•
An Online Virtual Copy indicates that the Virtual Copy for the database is created while it is
OPEN (online).
•
An Offline Virtual Copy indicates that the Virtual Copy for the database is created while it is
CLOSED (offline).
•
A Datafile Virtual Copy indicates that the Virtual Copy for the database is created while it is
OPEN (online) and contains only datafiles (no archive log destination).
•
An Archlog Virtual Copy indicates that the Virtual Copy is created for archive log destination
only.
The status of a Virtual Copy can be either Available, Available(P), Orphaned, Removed,
Mounted
, Mounted(P), Database, or Stale.
•
Available status indicates that the Virtual Copy exists and is not currently mounted or cloned.
•
Available(P) status indicates that one or more virtual volumes of the Virtual Copy are
missing.
•
Removed status indicates that the Virtual Copy is removed.
•
Mounted status indicates that the Virtual Copy is currently mounted.
•
Mounted(P) status indicates that the Virtual Copy is partially mounted.
NOTE: To remount the Virtual Copy, use the rmora_mount command with the –r option.
To change the Virtual Copy status to Available, use the rmora_umount command.
•
Database status indicates that a database is cloned using the Virtual Copy.
•
An Orphaned status indicates the current database volumes are no longer the parents of the
Virtual Copy volumes.
•
A Stale status indicates that one or more virtual volumes of the database Virtual Copy are
stale.
The backup status of a Virtual Copy can be either Y or N, where Y indicates that the Virtual Copy
is backed up and N indicates that the Virtual Copy is not backed up.
