Recommendation - concurrent access multiple class v

Hi! I've just started to architect a new system, stateless JSON API, which is expected to have very high load and to require more servers for parallel deployments (same app across multiple servers). I am considering using ObjectDB, because of its advantages and easy usage, but I'm afraid that it might get corrupted because the manual says that we must not access ObjectDB with different versions of a class. Let's take the following scenario: ... Would ObjectDB support this scenario, where the previous version of a class is used by some servers, then others come with the new version, then finally all of them get the new version? So...basically...concurrent access with version x and version ...

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)... hi, additional info,  First version of query gives result in 50ms for first 40 records from database but second version which queries 40+ records gives 19 seconds. We pinpointed that from he ...

How to Use a SF with extended Persistence Context?

Hey, I have a problem to use SF with an Extended Persistence Context Regarding to Transactions. The need for an extended persistence Context emerges for the need to create queries in advance for fast execution so I need to store the queries and I need an EntityManager that doesn't get closed between calls. When I call the SF directly no problem happens but if I use SL to hold a reference to the SF I get com.objectdb.o._PersistenceException: Attempt to begin a new transaction when a transaction is active. ... 13:52:01,121 INFO  [org.jboss.modules] JBoss Modules version 1.1.1.GA 13:52:01,304 INFO  [org.jboss.msc] JBoss MSC version 1.0.2.GA 13:52:01,347 INFO  [org.jboss.as] JBAS015899: JBoss ...
