Hot update concerns

["Chen, Jennifer" <je...@sap.com>]

Hi, why is it not advisable to use hot update in a real-time system?
What are the concerns? I found the following paragraph online.

Thank you!

"Hot update is the ability to make changes to an existing Web service
without shutting down the system. This is an important feature and
required in a testing environment. However, it's not advisable to use
hot update in a real-time system, because it could result in the system
leading into an unknown state. Additionally, there's the possibility of
loosening the existing service data of that service. To prevent this,
Axis2 comes with the hot update parameter set to FALSE by default. If
you want to have this feature, you can do this by changing the
configuration parameter like this: <parameter
name="hotupdate">true</parameter>"

The problem is how update in changing an existing service , so the way
Axis2 deal with that is undeploy the service and deploy the service
(something similar to that). So if there are already processing request
then system may lead to an unknow state. Because of classes and property
reinitialization.
