Veritas Storage Foundation for Oracle.
To determine whether this product is installed on an \1 system, enter:
lslpp -L VRTSdbed
The dbed_ckptdisplay command displays Storage Checkpoints associated
with the current Oracle instance. One or all Storage Checkpoints may
be displayed, depending on whether the -c option is used.
You can also use the command to display fileset quota values using
the -Q option. Quotas limit the use of two principal resources:
files and data blocks. Each quota consists of two limits for each
resource:
-
The hard limit represents an absolute limit on data blocks or
files. A user can never exceed the hard limit under any circumstances.
-
The soft limit is lower than the hard limit and can be exceeded
for a limited amount of time. This allows users to temporarily exceed
limits as long as the limits are met before the allotted
time expires.
Storage Checkpoint information is displayed with the following columns
of output:
Storage Checkpoint Creation Time Status
--------------------------- ------------------------ -------
Checkpoint_975876659 Sun Dec 3 12:50:59 2003 P+R+IN
Checkpoint_974424522_wr002 Thu Nov 16 17:28:42 2003 C+W+ON
Checkpoint_974424522_wr001 Thu Nov 16 17:28:42 2003 C+W+ON
Checkpoint_974424522 Thu Nov 16 17:28:42 2003 C+W+M+ON
The Status column of dbed_ckptdisplay output can
contain the following values:
-
C
-
Indicates that the Storage Checkpoint is
complete.
That is, every file system that the Oracle database resides
on contains the Storage Checkpoint.
-
P
-
Indicates that the Storage Checkpoint is
partial.
That is, some file systems on which the Oracle database resides do
not contain the
Storage Checkpoint. This can occur in three different circumstances:
(1) When a file system runs out of space, one or more of the Storage
Checkpoint components can be removed. See the
dbed_ckptremove
command for more information.
(2) When the Oracle database changes shape (that is, has tablespaces and datafiles
added or deleted), more file systems may be added to the configuration.
Since these file systems were not present when the Storage Checkpoint
was created, the Storage Checkpoint appears to be only a partial image
of the Oracle database.
(3) Storage Checkpoint elements can be removed at any time by a database administrator.
-
R
-
Indicates that the Storage Checkpoint is read only. It has not been modified and
therefore is a consistent point-in-time image of the Oracle database
and file systems.
-
W
-
Indicates that the Storage Checkpoint is writable. It has been mounted read/write
and potentially modified. Modified Storage Checkpoints are not valid
for Storage Rollback operations, since the data is in an unknown state.
-
M
-
Indicates that the Storage Checkpoint is mounted. If it is Read Only,
it can be used with either the
dbed_ckptrollback
or
dbed_clonedb
commands. A mounted Storage Checkpoint can also be used for online
backup of the Oracle database or investigation using Oracle tools such
as
dbv.
-
ON
-
Indicates that the Storage Checkpoint type is Online.
-
OF
-
Indicates that the Storage Checkpoint type is Offline.
-
IN
-
Indicates that the Storage Checkpoint type is Instant.
-
I
-
Invalid for current ORACLE_SID. The SFDB repository
does not contain Storage Checkpoint information.
-
UN
-
Indicates that the Storage Checkpoint type is Unknown.
Database FlashSnap commands are integrated with Storage Checkpoint
functionality. It is possible to display and mount Storage Checkpoints
carried over with snapshot volumes to a secondary host. However,
limitations apply. For details, see the dbed_vmclonedb(1M) man page
or the Veritas Storage Foundation for Oracle Administrator's Guide.
The following options are supported:
-
-S ORACLE_SID
-
Specifies the name of the Oracle database for which Storage Checkpoints will be displayed.
-
-H ORACLE_HOME
-
Specifies the ORACLE_HOME setting for the ORACLE_SID database.
-
-c CKPT_NAME
-
Specifies a specific Storage Checkpoint to
display.
-
-o dbed | other | all
-
Specifies which Storage Checkpoints
to display. The default is to display only Storage
Checkpoints created by Veritas Storage Foundation for Oracle.
The display format of the other types of
Storage Checkpoints is different from the output of Storage
Checkpoints created by
Veritas Storage Foundation for Oracle.
-
-Q
-
Displays fileset quota values. The hard limit,
soft limit, and current usage are displayed for
each underlying file system in the Storage
Checkpoint. All values are given in file system
blocks. Note that the current usage of any file
system with the fileset quota feature disabled
will be displayed as zero. Fileset quotas are
supported with the Version 6 disk layout introduced
in Veritas File System 4.0.
-
-n
-
Disables SFDB repository refresh. By default, dbed_ckptdisplay will refresh
the SFDB repository if this option is not used.
-
-h
-
Shows command usage.
This example shows the Storage Checkpoint information that is
displayed for the Oracle database, PROD:
$ /opt/VRTS/bin/dbed_ckptdisplay -S PROD -H /oracle/product/9i

dbed_ckptdisplay can be run as either the Oracle DBA or the superuser. If you are running the command as root, use the -n option.
If neither the
-c
nor the
-o
options are supplied, then all Storage Checkpoints created by
dbed_ckptcreate
are displayed.
