JDO sequences from ORM file

I want to use sequences in JDO without using annotations. Normally this is done with a package-X.orm file, where X is a value passed to the PersistenceManagerFactory as the value of property "mapping". I'm encouraged to see that the JDO zip that comes with ObjectDB includes the DTD/XSD for this type of file, though I can't see a mention of it in the manual. ... insert formatted lines (e.g. Java code , stack trace ) - select a style in the toolbar and then insert the text in ...

Master database switching to read-only mode, possibly caused by slave failure

We had a database failure causing a production outage. Both master and slave databases have failed, slave became unresponsive and the master switched to read-only mode. By the look of it the slave database failed first and possibly caused the master to switch to read-only mode.

significant performance decrease

we are using objected in embedded mode (on OS X and WINDOWS). The database increased now to around 400000 entities of one class (database file size around 1.5 GByte). The response time of standard queries increased with this database size to an unacceptable rate (several seconds compared to around 30% when the number of entities was just half of the current). We tried to optimize the cache settings, current objectdb.conf is: <!-- ObjectDB Configuration --> <objectdb> ... insert formatted lines (e.g. Java code , stack trace ) - select a style in the toolbar and then insert the text in ...

Failover from Master to Slave

Good morning! I am interested in ObjectDB for a client project I am currently working on. In order to evaluate your tool I would like to know if your product has the ability to failover from a Master Database to a Slave Database and then recover back to the master when the master comes back online. I don't see any documentation about automatic failover.   Thanks Rich   ... insert formatted lines (e.g. Java code , stack trace ) - select a style in the toolbar and then insert the text in ...

JSON serialization and __odbHidden members

Hi.. Building a REST API (Jersey-based one) I noticed that object object I serialize to JSON has a clone field with "__odbHidden" suffix, e.g.there's  "id" and "id__odbHidden" is also (unwantenly) present with the same value. In general, we can annotate fields to include/exclude them from JSON serialization, but since these fields are not declared in my classes, I have no idea how to tell marshaller to avoid them. ... insert formatted lines (e.g. Java code , stack trace ) - select a style in the toolbar and then insert the text in ...

EntityManagerFactory Fails To Swtich Over To Slave When Master Is Unavailable

I have a simple task to validate the sample code will switch over to the slave database when the master is unavailable. I simulate the master unavailable by stopping the master server; which generates the following exception below. What am I doing wrong? It appears the connection manager fails to try the second URL in the list: objectdb://10.9.2.15:9998//10.9.2.15:9999/test.odb;user=admin;password=password Thank you in advance. ...
