Contracts ?

Hi There

I have noticed that one cannot alter a contract, there is no alter contract syntax.

I understand the reason is because one can break applications by altering messages in contracts used to build apps.

However now it seems that everytime i create a new message type i have to create a new contract which in turn i have turn alter a service to use it. I cannot drop and re-create contracts because they are bound by services.

So basically what i am saying is that it is really a mission to add new messages types in a complex SB application (create new message+create new contract+alter service), is this just the way it is or what am i missing here ?

Thanx

Indeed, changing contracts once an application started using them will break the apps. Similar to how one cannot change a COM interface after a component has shipped.

While in development, is an OK approach to drop the contract (and service) and recreate it again with the new message types. But once you deployed the app, the proper way to add new message types is to create new contracts. Typically this is done by creating a new contract that has all the previous contract message types and in addition, the new message types.

Contract and Queue confusion if named the same plus positioning issue.............

Hello,

The problem I was having regarding re-enable a queue was because it was in another database. I am guessing it did that because the contract and Queues have the same name. I double checked and nothing pointed to that database. I fixed it because I can re-enable the queue in the other database and it is fixed. My question is why did this happen? The other issue I am still having is regarding why the queue got disabled to begin with. I understand that it was because of positioning but do not understand how or why and how to provent it from being disabled.

Thanks,

Scott Allison...

You can have a contract and a queue inside one database with the same name without any conflict. You queue may be getting disabled due to poisoned message detection. You can read about this in Books Online. In short, if you receive from a queue and rollback 5 times consecutively, we detect that the queue probably has a bad message and disable it.
