Pessimistic Lock Timeouts setting

Hi,   I realise that JPA2 doesn't necessarily define a standard API way for Lock Timeouts. However, there is a standardised query 'hint' that can be setup to make the underlying DB lock a record for a specific time. The hint property is: "javax.persistence.lock.timeout" ... I haven't got an easily distributable test for replication, but It shouldn't take too long to write one up if required. ...

TYPE Expression

Hi there! Trying to add a simple type expression with the criteria api like in your sample: cb.notEqual(e.type(), cb.literal(Country.class)); results in the error: Caused by: com.objectdb.o.UserException: Attempt to store an instance of a non persistable type java.lang.Class at com.objectdb.o.MSG.d(MSG.java:61) at com.objectdb.o.TYW.writeElement(TYW.java:223) at com.objectdb.o.QRR.l(QRR.java:424) at com.objectdb.o.QRR.g(QRR.java:230) at com.objectdb.o.QRR.b(QRR.java:151) #1 2011-12-06 00:01 Hi there!

Connection is closed Caused by: java.io.EOFException

I am getting this exception on a regular basis, after a period of time of repeating the same code execution.  I don't understand why.  I restart the DB server and my code works again for another period of time until same exception is encountered again.  I cannot pin down a pattern e.g. after a certain period of time,  because the time  periods between exceptions are not regular, although frequent.  Any test case  I use will pass most of the time but will fail after an undetermined period. ... path = "$objectdb/db-files" /> <!-- <replication url="objectdb://localhost/test.odb;user=admin;password=admin" ...

Blocked by find

I have a container object which wraps an objectdb database. There is a "putIfAbsent(String id, Object obj)" method which is synchronized and attempts to load an object by id using the EntityManager "find" method. If nothing is returned from the db the passed object is persisted to the db. I have 5 threads which use this method. In a run today one of the threads seems to have got stuck somewhere in the find. The thread dump looks like: Bug Version: Priority: High Status: Fixed Replies: 23 Type:  Bug ...

Performance tuning, best practices

we have a system where we serve from a host process around 200 clients connected via webSockets (Jetty). The core process is running on a dedicated Windows 2012 server with 16 GByte RAM and 8 processor cores.  What is strange for us is that max 20% of the cpu resources are used and the IO subsystem is at maximum 30% of activity under heavy load but database queries are let's say not at the speed we would expect. We have currently 20.000.000 objects in the database, our configuration settings are: ... enabled="true" />   <!--   <replication url="objectdb://localhost/test.odb;user=admin;password=admin" /> ...
