Service Plans can be rebuilt on the Details page of the Cloud Portal.
Rebuilding a Service Plan may help resolve an issue and may be necessary when configuring or adding additional libraries (Jar files for example) to it.
Service Plan
The entire Service Plan is deleted and rebuilt. This includes:
The application's filesystem is unaffected by this operation and no application data or configuration is lost. The external IP address used by the Service Plan remains the same as does any domain configuration.
Note that the application is unavailable to end users while the Service Plan is restarting.
Application Container
Any Application Container can be restarted. The application's filesystem is unaffected by this operation and no application data or configuration is lost.
When restarting all the Application Containers of a Service Plan the application will be unavailable to end users until it has finished restarting. If restarting a subset of the Service Plan’s Application Containers the application will remain available to end users, but those users being served by the restarted Application Containers may be disrupted.
Application Databases
Each Application Database can be stopped and then started. This makes the database unavailable to the application and may impact your end users.
