Re: embedded CIM Instance

What you describe sounds a lot like Sfcb
does not handle embedded instances very well. To determine if that's actually
the case you could track the CIM-Xml exchanged between your client and
the CIMOM.

If it proves true that SFCB does not
write the EmbeddedInstance qualifier, you should open a Bug against SFCB.

Re: embedded
CIM Instance

----------

What to the strings look like and what does the cim/xml
look like? If the cim/xml does not contain the embeddedobject attribute
for the property, the client could not determine if the strings received
are actually embedded objects. Remember that in cim/xml today.

1. EmbeddedInstance and object properties are defined in mof as a string
type with a qualifier to identify them as embedded objects or instances.

2. The embedded instance is normally encoded in the cim/xml protocol/encoding
as xml with the xml special characters escaped and the embedded Object
attribute in the cimx/ml to tell the receiver that this is an embedded
object.

3. In pegasus, we actually added an embeddedinstance DataType and attempt
in the client infrastructure to decode your object if the attribute is
attached.

Note that we are finishing some extensions to our command line client tool
cimcli that adds capabilities for embedded instance/object creation, display,
etc. and that will shortly be in Pegasus head of tree It can be seen
now as bug 9007 (preliminary) and PEP 361.

Thanks for your message at 11:53 PM 8/18/2011. Your message was:

Hi all,

We need to return an array of CIM Instances in a vendor extension
method in our CMPI Provider. we have defined the method as follows:

uint32 xxx(

[IN (false), OUT, Description ("xxx"), EmbeddedInstance( "Our_Class")]

string instances[]);

From provider code we are adding out argument of type CMPI_instanceA.

Our client uses SBLIM 2.0.9.3 to get CIM Instances. When we are using OpenPegasus
as a CIMOM, client receives the data as an array of CIM Instances properly.
But when we use SFCB in Vmware ESX as CIMOM . Client is receiving it as
array of strings only, not as CIM Instances.

Any help?
