At a user site, an administrator can set up a procedure for filtering collaboration messages and using email or email pager to notify someone who can resolve problems. Because of this, it is important that the error numbers and the meanings associated with the numbers remain the same after the first release of a collaboration template. You can change the text associated with an error number, but you should not change the meaning of the text or reassign error numbers.
If you change the meanings associated with error numbers, make sure you document the change and notify users of the collaboration template.
You can change a collaboration's message file while the collaboration object is running. However, the changes do not take effect until the next time the collaboration object is started and the message file is read into memory. If InterChange Server goes down while collaborations are running, the server automatically reads into memory the message files for all collaborations that were previously running.
