Hello, Today I've started to test Oct2014 release. I upgraded the database with no issues and downloaded latest JDBC driver monet-jdbc-2.12.jar . When I try to connect to the upgrade database I get an error about tracelog. Here is the log file: 2014-11-11 08:54 INFO Creating new connection for [{Default group}/DRMAX - DEV] for driver=nl.cwi.monetdb.jdbc.MonetDriver and URL=[jdbc:monetdb://lux-dev1-ana.dev.ceosdata.com:50000/zkdev1] 2014-11-11 08:54 INFO Adding ClassLoader URL=file:/home/rbiciste/tools/lib/monetdb-jdbc-2.12.jar 2014-11-11 08:54 ERROR Error connecting to the database using URL=jdbc:monetdb://lux-dev1-ana.dev.ceosdata.com:50000/zkdev1, username=drmaxtst SELECT: no such operator 'tracelog' [SQL State=08001] java.sql.SQLException: SELECT: no such operator 'tracelog' at nl.cwi.monetdb.jdbc.MonetConnection.<init>(MonetConnection.java:254) at nl.cwi.monetdb.jdbc.MonetDriver.connect(MonetDriver.java:171) at workbench.db.DbDriver.connect(DbDriver.java:429) at workbench.db.ConnectionMgr.connect(ConnectionMgr.java:228) at workbench.db.ConnectionMgr.getConnection(ConnectionMgr.java:158) at workbench.gui.components.ConnectionSelector.doConnect(ConnectionSelector.java:233) at workbench.gui.components.ConnectionSelector$2.run(ConnectionSelector.java:133) Caused by: nl.cwi.monetdb.mcl.MCLException: SELECT: no such operator 'tracelog' at nl.cwi.monetdb.mcl.net.MapiSocket.connect(MapiSocket.java:311) at nl.cwi.monetdb.mcl.net.MapiSocket.connect(MapiSocket.java:398) at nl.cwi.monetdb.mcl.net.MapiSocket.connect(MapiSocket.java:252) at nl.cwi.monetdb.jdbc.MonetConnection.<init>(MonetConnection.java:232) ... 6 more Any help would be appreciated.
