Connecting to a remote objectdb server

I am trying to configure my application in a client-server objectdb setup via tcp/ip. So I first made sure that the remote objectdb server is running using telnet from my local.  $ telnet db.mydomain.com 6136 (worked fine, is able to connect...) My db was configured below: <server>   <connection port="6136" max="100" />   <data path="objectdb://db.mydomain.com/db" /> </server> ... root folder and create *.tmp files. Which I believe are temporary db files.   ...

Querying error - java.lang.ClassCastException: com.objectdb.o.STV

I'm getting the ClassCastException below when querying objects. As yet I haven't been able to track down the exact circumstance in which it occurs - saving and querying objects works fine on attempts to recreate - but presumably at some point an object gets saved which objectdb doesn't like. Any pointers as to what is wrong or approaches to investigate further would be much appreciated. ... it might help.   In addition, a temporary property on the client side disables the suspected optimization: ...

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: ... If you run build 2.3.3_02 with the new temporary  "objectdb.page.circle" system property set to "true" - a ...

Performance problem

Hi, we have a strange performance problem with ObjectDB 2.5.3_01 and JBoss 7.1.1. We have two ObjectDB databases on one ObjectDB server. Production database is running 5-10 times slower than test database. Their size and number of records are almost identical. When running production database in separate test environment its speed is very good. We did a performance analysis on our 2 linux servers one running JBOSS and other running ObjectDB. - CPU utilization of JBOSS server is max 5-10% (per core)... same one mentioned in this issue. We solved this problem temporary by migrating all data to new database. We would appreciate if you ...
