If you were able to save the connection that you changed, that should be enough.  I'm not really sure what implications there would be for any running MCF agents or UI processes though, so you'd probably want to shut everything down before trying that.

Hi Karl,
 
is it possible to update the classnames in the database for existing connections depending on renamed classes?
It would be nice to spare the effort of recreating all the connections.
 
I looked into the code of the SynchronizeConnectors command and explored the API:
 
What about
 
IRepositoryConnection[] connections = connManager.getAllConnections();
...
connection.setClassName(mappedClass);
...
connManager.save(connection);
 
I tried it and so far it seems to work.
Do you see any pitfalls with that solution?
 
Regards,
Markus

Betreff: Re: Renaming Connector Classes
Hi Marcus,
 
The name of the connector class is a key for the connection names that depended on that class.  To rename a connection class, therefore, you need to do the following:
 
(1) BEFORE renaming the class, delete all jobs and connections that refer to that connector.
(2) UNREGISTER the connector class (there's a command-line utility for that)
(3) BUILD your new class
(4) REBUILD everything you deleted

Hi,
 
i need to rename some connector classes.
When starting MCF with the renamed classes, i obviously stumbles over the old connections using the old classnames.
It would be nice to be able to migrate the old connections to the new classnames.
 
I found the commands SynchronizeConnectors, SynchronizeAuthorities and SynchronizeTransformations.
But they leave the existing connections with "unregistered" connector classes.
 
Is there another command for mapping/renaming connector classes for existing connections?
 
Thanks in advance,
Markus
