Investigating I/O Performance for SG Oracle RAC: Storage Mapping
Oracle File Mapping (ORAMAP)
Chapter 6
132
From Oracle Enterprise Manager, you can view storage mapping information and a
graphical display of the storage layout. Storage mapping information cannot be viewed
with the Oracle 10g version of the Oracle Enterprise Manager client. However, the
Oracle9i version of Oracle Enterprise Manager can be used with Oracle 10g to view
storage mapping information.
For more information about Oracle Enterprise Manager, refer to your Oracle
documentation.
To view storage information
1. To view storage information, start Oracle Enterprise Manager and select a database
from the left navigational pane (the object tree) of the Oracle Enterprise Manager
Console.
2. Expand the Databases icon and select the desired database.
The Database Connect Information window appears.
3. Enter a user name and password to log in to the database and click OK.
4. In the object tree, expand the Storage icon.
5. Under the Storage icon, expand the Datafiles icon.
6. Select the datafile for which you want to view storage layout information.
7. In the right pane, click the Storage Layout tab.
8. Expand the objects to display their storage layout.
Within the Oracle Enterprise Manager Console, you can point to an object on the
screen and a description of the object is displayed in a pop-up field. If an object name
or path appears truncated, point to it and the pop-up field will display the full object
name and path.
9. By default, storage layout information appears in tabular format. That is, the
Tabular Display icon is selected. To view a graphical display of the storage layout,
click the Graphical Display icon.
10. Expand the objects to display their storage layout information graphically.
11. To exit, choose Exit from the File menu.
About Arrays for Storage Mapping and Statistics
SG Oracle RAC provides “deep” mapping information and performance statistics for
supported storage arrays. Deep mapping information consists of identifying the physical
disks that comprise each LUN and the hardware RAID information for the LUNs.
NOTE To use deep mapping, you must have Oracle 9.2.0.3. or later installed.
Veritas Array Integration Layer (VAIL) software interfaces third-party hardware storage
arrays with Veritas storage software. VAIL providers are software modules that enable
Veritas applications to discover, query, and manage third-party storage arrays. The
vx_emc_symmetrix provider manages EMC Symmetrix arrays.
For the most up-to-date array support information, see the appropriate hardware
compatibility list (HCL) on the Veritas Technical Support Web page at:
