What changes require a restart?

[AG_10348570]

I am using Windchill PDMLink Release 12.0 and Datecode with CPS 12.0.2.13

How would I know whether or not a change to code in my codebase requires a restart of windchill to deploy? For instance, some customizations/changes can be deployed when windchill is up and will take effect and others require windchill to be down. So how do I tell whether or not deployable code requires a restart?

Similar discussion - "Is it possible to modify the code and without a restart of method server see the new reflected changes?": https://community.ptc.com/t5/Windchill-Customization/Is-it-possible-to-modify-the-code-and-without-a-restart-of/td-p/52028

Generally yes, code changes will require restart since the class might have been loaded into the JVM memory already. There are some exceptions. 

https://www.ptc.com/en/support/article/CS35160?source=search That article talks about property files changes (like site.xconf changes). If the classes are new and not invoked yet, likely no restart is needed. If you are updating existing classes with modification, I would restart. If you are doing JSP changes, you can set tomcat to run in development mode. Any modifications will cause the JSP to be recompiled which is handly not having to clear work cache all the time.

Hi @AG_10348570 

If you use an IDE and debug mode for coding, your ide is connected to the method server.

Each compilation tries to deploy the modification to the vm memory and a change is instantly applied but there are several changes that require file class deploy and restart.

• Adding a public method in the class 
• Removing a method in the class
• Renaming a method in the class

All this changes need the restart

With following information the change is applied

With following information restart is needed
