After an abnormal shutdown, cannot connect to derby DB.
-------------------------------------------------------
Key: DERBY-4697
URL: https://issues.apache.org/jira/browse/DERBY-4697
Project: Derby
Issue Type: Bug
Components: Store
Affects Versions: 10.3.3.0
Environment: Linux RHEL5. 64 bit. Embedded DERBY.
Reporter: Michael Closson
My company uses embedded derby DB for persistence (w/ hibernate) in one of our
server products. We have been using it for several years now.
We are using derby version 10.3. (Bundle-Version: 10.3.1000004.561794)
Recently at a customer site, the server couldn't start because it could not
connect to the database. It happened after the server shutdown abnormally. The
error message reported in the log file is:
Caused by: java.sql.SQLException: Failed to start database 'db', see the next
exception for details.

Indeed, if I try to connect to the database with IJ, I get the same error.
If I connect with jars that I built from derby source (10.6, latest) I get a
different error:
[mclos...@magrath work]$ java org.apache.derby.tools.ij
ij version 10.6
ij> connect 'jdbc:derby:db';

Perhaps derby wrote an incomplete log record, and now cannot recover? Also, if
I delete the log control file (log.ctrl) then I can connect OK. But if I do
this, is there risk that some transactions will be lost? (I think so).
I have the database that causes this error, but I prefer to not post it to the
bug log or mailing list. But if someone emails me directly, I will supply it.
