Enable the app-optimized compression for Oracle backups
When you enable the app-optimized compression for Oracle backups, the app-optimized compression improves the deduplication rate and reduces the overall storage that is required for the backups. You can enable app-optimized compression through either the
PowerProtect Data Manager UI or the appropriate commands at the command line.
NOTE:
Enabling or disabling the app-optimized compression feature impacts the deduplication and storage usage of a new backup.
If app-optimized compression is required for an Oracle protection policy, it is recommended that all the required storage units be created with the Oracle app-optimized compression feature before you create the protection policy.
A storage unit that is enabled for Oracle app-optimized compression cannot be shared with other applications.
After you enable the Oracle app-optimized compression for a storage unit, the term AO is displayed after the storage unit name on certain pages in the
PowerProtect Data Manager UI. When you add or edit a protection policy in the
PowerProtect Data Manager UI, the term AO is displayed on the policy
Objectives and
Summary pages. The term AO is also displayed on the
Protection Policies details page.
Enable the app-optimized compression through the
PowerProtect Data Manager UI
Oracle app-optimized compression through the
PowerProtect Data Manager UI is only supported for Oracle workloads with DDOS 8.1 or later.
To enable the app-optimized compression option through the
PowerProtect Data Manager UI, set the required UI option when you create or edit the storage unit for use with protection policies.
Complete the following steps to create the storage unit and enable the option.
From the left navigation pane, select
Infrastructure > Storage.
The
Storage window appears.
On the
Protection Storage tab, select a storage system and then select
More Actions > Manage Storage Units.
The
Storage Units page opens and displays a list of the storage units under the control of
PowerProtect Data Manager.
Select
Add.
The
Create Storage Unit dialog box opens.
Set all the required options in the
Create Storage Unit dialog box, as described in the topic "Create a storage unit" in the
PowerProtect Data Manager Administrator Guide.
To enable the app-optimized compression for the storage unit, click the toggle button for the
Oracle App-Optimized Compression option to change the setting to
Enabled.
Complete the following steps to edit the storage unit option settings as required.
From the left navigation pane, select
Infrastructure > Storage.
The
Storage window appears.
On the
Protection Storage tab, select a storage system and then select
More Actions > Manage Storage Units.
The
Storage Units page opens and displays a list of the storage units under the control of
PowerProtect Data Manager.
To view the details or usage for a storage unit, select
for that storage unit.
The
Details pane opens and displays the name, type, capacity, quota information, and a list of protection policies that currently target the storage unit.
The storage unit may contain copies from protection policies that no longer target the storage unit.
Select the appropriate storage unit from the list, and then select
Edit.
The
Edit Storage Unit dialog box opens.
Set the required options in the
Edit Storage Unit dialog box, as described in the topic "Edit a storage unit" in the
PowerProtect Data Manager Administrator Guide.
To change the app-optimized compression for the storage unit, click the toggle button for the
Oracle App-Optimized Compression option to change the setting as required.
Enable app-optimized compression through the command line
To enable the app-optimized compression through the command line, perform the following steps for a storage unit that is created by a
PowerProtect Data Manager protection policy for Oracle backups on a DD system.
To identify the storage unit and DD server IP address, run the
./ddutil -s command in the
$RMAN_AGENT_HOME/bin directory on the Oracle RMAN agent host.
To enable the app-optimized compression, run the following commands on the
PowerProtect DD:
mtree option set app-optimized-compression oracle1 mtree /data/col1/orcl-16k-x4-m-re-07-sip1-1dfaemtree option show mtree /data/col1/orcl-16k-x4-m-re-07-sip1-1dfae
