C. Known Issues
----------------
1 Add Row with duplicate key gives 'success' message.
The row is actually not added to the database.The message
is misleading and can be ignored.
2 Stopping/Restarting DMI SP (Service Provider) stops the WbemdmiP
operation. While running Wbemdmip, if the service provider is
stopped and restarted, the provider returns the WBEM_E_FAILED message.
The workaround for this is to stop and restart CIMOM.
3 Modifying a ReadOnly attribute gives success message, when all
the attributes in the row are also ReadOnly. The attribute is not
modified but the message is misleading and can be ignored.
4 Unsupported attributes have no access qualifiers. The access qualifiers
like 'ReadOnly','WriteOnly' and 'ReadWrite' of 'Unsupported' attributes
are not displayed. This should not pose a problem as these attributes are
Unsupported and would have no need of these operations.
5 Value of Unsupported attribute displayed as NULL. In the DMI Service
Provider 2.0 the value field of Unsupported attributes contains the text
"Unsupported". Due to interface constraints, the DMI provider cannot get this
information. For consistency with CIMOM data display scheme, the provider
will display 'NULL' for the value field of Unsuppoted attributes.
6 Modify Unsupported attribute gives 'success' message. The modify
operation fails as it should but the message is misleading and can be ignored.
7 Invalid value set to date type attribute gives 'success' message
(check with new SP 2.54)
8 As a general rule key attributes should not be modified. However, DMI permits
modification of key attributes. In the WBEM DMI provider, if the key value is modified:
a) to a value that already exists as a key in the database then that row is overwritten
with the modified values, losing its existing data. The row under modification
remains unchanged and can still be accessed.
b) to a new value then a row add operation is done with the new key and the row under
modification still retails its original values. The database now has an additional row.
In effect, in both cases, the row under modification does not change its key value and
can still be accessed.
Workaround for b) Get the new key values as well the values of all attributes in the row
under modification. Now, do a RowAdd operation with these values. Next do a DeleteRow
operation on the (original)row whose key value you wished to modify. This will leave you
with the new modified row.
9 Adding another row to a scalar group gives 'success' message.
This is similar to #1, #3 and #6 above. The operation of row addition is not done but the
message is misleading and can be ignored.
10 Value of Write-Only strings displayed as NULL. This is similar to
#5 above. The value field in the DMI SP contains the text "Write
Only" but in the WbemdmiP provider it is displayed as NULL in the
value field.
11 Value of Unknown attribute displayed as NULL. This is same as #10
12 The 'Reserve' and 'Release' operations on an attribute as explained in the
DMI spec v2.0 are not supported.
13. CIMOM applications won't be able to receive class creation and deletion events that
correspond to DMI group addition and deletion notifications. This is because
CIMOM does not support the above events. This Beta release of the DMI provider does not
support extrinsic DMI events (events other than the standard DMI notifications).
14. The WBEM* Object Browser is incompatible with the DMI provider. If you try to view
the DMI classes with the object browser, you may get an error. The WBEMTEST*
application, however, works fine with the provider.
15. The Dmitest.exe sample application requires the sample MIF files be installed in the
C:\TESTMIFS directory. Alternatively, you may edit the dmitest.scr file and change the
location of the MIF files used in the script file to point to where the files exist on
your system.
D. Operating Instructions
-------------------------
For Windows '95, Windows '95 OSR2, you need to have DCOM installed before running the Wbemdmip
provider.
The Intel DMI 2.0 Service provider must be installed and running before starting
Wbemdmip (ie. before starting CIMOM)
