Issue with using imported schemas in BPEL

Question

Hi
I am using one main schema (1) in which I am importing another schema (2. sugarHill.xsd) elements using references(sh) in BPEL assign/transfermations
to pass the values in target. But when I execute the process what I observe is that main schema element values (artist) & reference varialbe(sh:album) in main schema values are coming properly in input variable but in assign/transfermations the reference used in main schema (sh:album) varialbe values in source coming as empty/null. I tried couple of options but didn't work out. Please let me know how can I get and pass the reference variable value in assing/transermation bpel activity.
1. Main Schema.
<?xml version="1.0"?>
<xs:schema targetNamespace="http://www.newInstance.com/cd-database"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:sh="http://www.sugarhillrecords.com"
elementFormDefault="qualified"
>
<xs:import namespace="http://www.sugarhillrecords.com"
schemaLocation="sugarHill.xsd"/>
<xs:element name="cd">
<xs:complexType>
<xs:sequence>
<xs:element name="artist" type="xs:string" />
<xs:element ref="sh:album" />
</xs:sequence>
<xs:attribute name="title" type="xs:string" />
</xs:complexType>
</xs:element>
</xs:schema>
2. sugarHill.xsd
<?xml version="1.0"?>
<xs:schema targetNamespace="http://www.sugarhillrecords.com"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified">
<xs:element name="album">
<xs:complexType>
<xs:sequence>
<xs:element name="description" type="xs:string" />
<xs:element name="producer" type="xs:string" />
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
Thanks

Hi James,
actually we tried out the parameters you had suggested but not seeing improvement...
-- are there any other options for us or any other things/workaround which we could try out ..to me it looks like because of the slowness of the AQ adapter to de-queue the b2b message payload from the IP_IN_QUEUE that we are getting limited bpel processing speed...
-- our's is not a RAC enviornment as you had asked before ..are there are any AQ queue parameters to speed up the processing speed which could be setup in the INIT.ora file ..
--- also it seem not sure though that the aq_tm_processes parameter is depricated in 10g... and there is another parameter job_queue_processes parameter....i am not really sure how this parameter improves parallel processing or even works..
-- also is it true that number of subscribers/listeners for the queue also limits the processing speed... for the seeded internal B2B queue IP_IN_QUEUE is there any way to figure out how many subscribers are listening to this queue for the de queue operation.
-- one more question we had is it possible that from the b2b side when i process 1000 messages means 1000 edi files
that i could enqueue 500 messages to one custom queue q1 while the remaining 500 messages to the other custom queue q2.. could this be of any help to us ...
If yes could you please help us out with the queue creation pl/sql scripts if any..as to how we could create our custom queue on the B2B side... i am not sure what setups would be involved for doing this as well what setups would be required on the B2B trading partner setups to force the b2b messages to go to this custom queue..even if we are able to create custom queues ...
Thanks for your response though ..surely would await your reply to my queries here...
Thanks
