1: modifying service contracts?
Posted by Mohan Pakkurti on 10/03/02 01:56 PM
I have a question about service contracts. What is the method to change a ac_sc_msg_type that has been already defined in the system.

Example, I like to change... 

   foo := acs_sc_msg_type.new (
            msg_type_name => 'foo_name',
            msg_type_spec => 'foo_var:string'
        );
to 
   foo := acs_sc_msg_type.new (
              msg_type_name => 'foo_name',
              msg_type_spec => 'foo_var1:string,foo_var2:string'
          );
Is there a function that can be used to do this easily?

Thanks for any tips.

Mohan,

there is no function to change the ac_sc_msg_type in a running system. However, you could drop all implementations of the service contract to then drop the service contract it self. After dropping the service contract you can recreate the service contract with the correct message type. Dropping and recreating the service contract its implementations is done through their sql drop and create scripts.
