[jira] [Commented] (DERBY-6930) Embedded driver database remains locked after close

JIRA jira@apache.org

    [ https://issues.apache.org/jira/browse/DERBY-6930?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15952281#comment-15952281 ]

Bryan Pendleton commented on DERBY-6930:
----------------------------------------

There's a difference between closing a connection, vs. shutting down the database engine.

Is that what your question is about?

Here's a bit of docs:

* Shutting down Derby or an individual database:  https://db.apache.org/derby/docs/10.13/devguide/tdevdvlp40464.html

* Working with multiple connections to a single database: https://db.apache.org/derby/docs/10.13/devguide/cdevconcepts34828.html
