Optimization Question

One of our uses for your ObjectDB software is in maintaining the current state of a large number of data objects called tracks. These tracks change very frequently over time (every 10-15 seconds is not unreasonable), but they are also very large complex data structures so it's extremely difficult to identify exactly what fields have changed from one update to the next. Currently the following sequence executes when a track update comes in: - If it’s a new track simply add it to the database.... Maximum file size: 32 MB 0 ...

Replicated cluster recovery

If I create a replicated database cluster as per http://www.objectdb.com/java/jpa/tool/replication what is the behaviour of the master database after a failure? For example, say I have MasterDB and SlaveDB in the cluster. If MasterDB goes offline the application will automatically switch to SlaveDB. When MasterDB comes back online it will have missed any activity that occured during the downtime. ... Maximum file size: 32 MB 0 ...

Missing Data on Retrieval (0, null values)

I try  to export all Objects in an Flatfile-Hiearchy (.csv). But only the first exported Table contains all necessary Data. Most of the others  contains all  Object-Rows', but most Values of the Columns are missing. With a  em.clear() inside the Loop, all tables are exported correctly but the Enity-Keys do not match. I can't get the point - what am i doing wrong?   emf = Persistence.createEntityManagerFactory(dbFile); em = emf.createEntityManager(); ... Maximum file size: 32 MB 0 ...

Sort of very large objects - out of memory

The attached test is failing with an out of memory exception when running with -Xmx512m It performs the following actions: 1) Create 5 persist threads which create and persist a large object in a loop 100 times each 2) Create 5 get threads which read 100 objects each in a loop based on object creation time and priority The message size should be around 1mb so I think there should be around 11mb of "live" data in play at any time. The objectdb cache settings are low in the config - database section is below for reference. ... Maximum file size: 32 MB 0 ...
