Thanks for your response.
I’m using webMethods 9.12 by the way.
I think that the weMethods Deployer documentation is not clear on this point (see below):
Sync Document Types Whether Deployer should synchronize
the publishable IS document types in the
source package with documents types on the
webMethods Brokers that are connected to the
target Integration Servers.
Note: The connected webMethods Brokers
must be available at deployment time for
synchronization to occur. If a connected
webMethods Broker is not available, IS
document types are not synchronized for the
Integration Server to which the webMethods
Broker is connected. Deployer writes a
message to that effect to the deployment
report. Deployer can detect webMethods
Broker unavailability when you generate the
simulation report and will write a message
advising you of the problem to the report.
