Re: How to delete dataset and lucene (write.lock) over API

Wed, 17 Jun 2020 09:07:06 -0700 

Ivan,
I've tidied up removal of non-managed datasets (e.g. --conf=) for the next release but I havent' managed to recreate exactly what you see. 


Now, if you delete a non-managed datasets, it gets removed from the 
running server. The persistent state is not deleted - it can be cleaned 
up later outside Fuseki.

Hi Andy

Thank you very much for the clarification.

The server I was running is 3.14.0. I'm using this Docker image:
https://hub.docker.com/r/stain/jena-fuseki

The creation and deletion was done on the command line with curl, so
nothing else was accessing the server.

I've failed to provide the config.ttl file in my initial post.

Best,
Ivan

Hi Ivan,

The "delete database" only works with databases created via the UI, not
via a provided configuration file (actually ones laid out in the /run/
area if you want to mimic that).

When I tried it I got a different error:

"""
[2] There are 0 configuration files, not one.
"""

and no stacktrace.

Which version of Fuseki are you running?
Was the server doing anything else at the time?

Dear all

I've successfully used the Fuseki2 Administration API (


https://jena.apache.org/documentation/fuseki2/fuseki-server-protocol.html)

to create and delete a dataset (the dataset config is appended). Thank

you

very much for the easy to use API.

After deleting a dataset, trying to recreate it, fails. Fuseki2 throws

the

appended stack trace.

Is there a way to remove the lucene index and the lock over the
administration API?

Cheers,
Ivan
