Hi Rajith,
You are right, there is no well defined way. Before deleting the UM data and
Registry data, I have already deactivated the tenant.
The exception below happened on my re-creation of the tenant with the same
name. Please advice whether it's the problem that the Registry cache was not
cleared up?
Thanks, Wenxing

Hi,
ASFAIK there is no well defined way to delete a tenant. You can deactivate a
tenant. If you are using custom code then this error may be due to starting a
wrong tenant flow in your code.
Thanks!

Thanks to Lakshani and Kasun.
Regarding the TenantMgtListener extension, any reference or example to do the
cache clearing since our application is a WEB application?
Thanks again, Wenxing

This sounds like a bug. When a tenant is deleted, the cache should be cleared
automatically. You shouldn't have to wait for the periodic cache cleanup.
My suggestion is to write a TenantMgtListener extension, and add it to the
product. In there, you can add a cache clearing operation for the tenant
pre/post delete method.

Dear all,
I am trying to remove a Tenant from the WSO2, but I found the following
exception after removing a Tenant and then re-create it:
