Hi, We have a service in our company that works with derby embedded db in a server mode. I have an ongoing task which uses the db, and in one of the times I got the following exception:
:52:44.961 WARN - JDBCExceptionReporter.java:77 (logExceptions) - SQL Error: 40000, SQLState: 08006 07:52:44.961 ERROR - JDBCExceptionReporter.java:78 (logExceptions) - A communications error has been detected: Connection reset by peer: socket write error. When I tried to reconnect to the server again I got the followings: "SQL State XJ041 Error Code 40000" Which mean by the derby manual: XJ041 - Failed to create database '<databaseName>', see the next exception for details. So I removed the property create=true and I got: got "SQL State XJ040 Error Code 40000" Which means by the manual: XJ040 - Failed to start database '<databaseName>' with class loader <classLoader>, see the next exception for details. This probably points that my database was in an inconsistent state (something similar: http://www-01.ibm.com/support/docview.wss?rs=180&context=SSEQTP&dc=DB560&dc=DB520&uid=swg21288806&loc=en_US&cs=UTF-8&lang=en&rss=ct180websphere). I read the from the derby site: http://db.apache.org/derby/manuals/develop/develop13.html#HDRSII-DEVELOP-18166 that a A transaction log prevent the DB from being in an un-persistent state. So my guessing is that maybe writing to the log failed...? Is there any solution to this and I do not mean automated backups, the db must be persistent even if writing to the log failed. Maybe something to tune ? Nadav hoze Java programmer dbMotion Ltd.
