Request clarification of changes to accessor enhancement policy (non-getter prefix instead of getter suffix) AND annotations

In response to the forum posting http://www.objectdb.com/database/forum/994 changes were made to the way enhancement treats getters and setters (property accessors), namely there are no longer enhanced additional getters/setters, because the additional methods now use (since about version 2-6-5) this pattern: __odbHidden_[accessor_name] Instead of this pattern with a suffix (preserving the method as a setter or getter), prior to version 2-6-5: #1 2016-08-20 13:44 In response to the forum posting http://www.objectdb.com/database/forum/994 changes were made to the way enh ...

ObjectDB 2 JDO Manual

The new ObjectDB Manual describes how to use ObjectDB 2 with JPA. An additional manual that focuses on using ObjectDB 2 with JDO can help JDO users. But since writing a new manual and then maintaining two similar manuals, one for JPA and the other for JDO requires sufficient effort, this will be done only if there is sufficient demand.  ... we used odb104fe, and I was happy to see the updated web page and the support for JPA when I returned to your site today. However, it is ...

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.

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)... with schema changes, as explained in this manual page . But this forum thread is about performance, so now that the performance ...
