the vault sync when we changing the SyncMode SYSTEM to SITE getting error

[YK_10474275]

I am using Windchill PDMLink Release 12.0 and Datecode with CPS 12.0.0.0

While performing the vault sync when we changing the SyncMode SYSTEM to SITE through jconsole it's getting below error

Problem invoking modeSwitchToSite: java.rmi.UnmarshalException: Error unmarshaling return: nested exception is:
java.lang.ClassNotFoundException: wt.util.WTException (no security manager. RMI class loader disabled)

Here are the errors that I faced

Hi @YK_10474275 

I use PTC Knowledge Base Search and I've got a result

CS198791 RMI class loader disabled

In your specific case I guess that you just do not use correct java library from Windchill. 

"wt.util.WTException" is a class from Windchill and this class can not be missing  

This class is located in a folder > WTHOME/codebase/wt/util/ 

check your application if it has access to the class
