PTV Logistics xServer Forum

Hi there,

one of my players creates HPRs in his local xServer2 environment.

He then deploys them on a remote machine but the graphs are removed automatically, probably because the server is configured with

• highPerformanceRoutingNetworkGarbageCollectionEnabled= true

After disabling the switch for the garbage collection he redeployed the graphs and they have not been deleted anymore.

But: the when he tries to list the HPRs they do not appear in the response. They are also not shown in the UserDataMonitor.

This raises the question:
What exactly is the definition of "garbage"?

PS: reminds me of this thread which deals with the DIMA garbage collection.

Here's the missing piece... In the subdirectories of a user's HPR space there are

• two files directoryControl and directoryControl.lck : these two files are used to detect whether something was changed. If the server is shut down you can delete these files: they will be recreated when the server is restarted.
• per each HPR there's anbother meta file (*.valid) and a subdirectory named after the graph. While the subdirectory contains the the graph itself the "*.valid" file shows the garbage collection whether the HPR is
  • to be seen as garbage / to not appear in the list-statement
  • to be seen as valid / to appear in the list-statement
  If a HPR is deleted via an xData.delete call this *.valid file is removed and this causes the garbage collection to clean this HPR in the next iteration.

So here's what we assume:

• In the customer's specific case either the surrounding directory structure based on tenant/scope is not proper or the *.valid files haven't been copied properly.
• In some rare cases the HPR may not match the server's configured map version.
