Hi,
Sure you can run
The service contract bindings of the initiator service (SVC1) are irelevant. Is the target service (SVC2) that has to be bound to a specific contract. Try altering SVC2.|||Create Service SVC1 ON QUEUE QUEUE1 (CONTRACT1);
alter service SVC1 (add contract CONTRACT2);
But You can only send message using contract1, when you try to send msg using contract2, it always say can not find CONTRACT "contract2".
The following query shows the contract is there.
select s.*,c.* from sys.service_contract_usages U
inner join sys.services S on S.service_id = U.service_id
inner join sys.service_contracts C on U.service_contract_id=C.service_contract_id
where S.name='SVC1'
declare @.lMsg xml
declare @.ConversationHandle uniqueidentifier
set @.lMsg = '<test>testing</test>'
Begin Transaction
Begin Dialog @.ConversationHandle
From Service SVC1
To Service 'SVC2'
On Contract contract1
WITH Encryption=off;
SEND
ON CONVERSATION @.ConversationHandle
Message Type [type1]
Commit
The above works, but the following will not work.
declare @.lMsg xml
declare @.ConversationHandle uniqueidentifier
set @.lMsg = '<test>testing</test>'
Begin Transaction
Begin Dialog @.ConversationHandle
From Service SVC1
To Service 'SVC2'
On Contract CONTRACT2
WITH Encryption=off;
SEND
ON CONVERSATION @.ConversationHandle
Message Type [type2]
(@.lMsg)
Commit
Any idea ?
Thanks!
I mean everywhere SVC2. it is a typo when I posted the msg, my bad.
But still the alter service is still not working, any idea ?
|||Works fine for me:
Code Snippet
use tempdb
go
create message type mt1 validation = none;
create message type mt2 validation = none;
create contract sc1 (mt1 sent by any);
create contract sc2 (mt2 sent by any);
create queue q1;
create queue q2;
create service svc1 on queue q1;
create service svc2 on queue q2 ([sc1]);
alter service svc2 (add contract [sc2]);
go
declare @.h uniqueidentifier;
begin dialog conversation @.h
from service svc1
to service 'svc2', 'current database'
on contract [sc2]
with encryption = off;
send on conversation @.h message type [mt2];
waitfor (receive message_type_name, service_contract_name, * from q2);
go

|||I am using distributed environment, It did not work when I tried.
I will re-test it, and update you.
|||It works, My bad, because I have different contract names, which caused the failure. Sorry for the late response.
