About delete


Once served to JSF page via @EJB query bean, many list fields are null (but same query ok after fresh persist in @PostConstruct)

I have marked this as CRITICAL because although there probably is no database integrity problem, the inability to robustly query relationship fields in a web application renders the ObjectDB system seemingly useless. objectdb-2.2.5_10 NetbeansIDE6.9.1 Glassfish3.01 client-server mode. odb file written to db-files/greendesk/greendesk.odb (see persistence.xml), copy of odb output attached. ... edit delete webel ... edit delete webel ...

Occasionally slow requests in load testing

We are running load testing against objectdb version 2.3.7_18. The performance is generally OK, however there are quite a few "spikes" in the performance where we are getting a lot of very slow response times from the DB, around 10 - 15 seconds. Looking at the DB server process with AppDynamics we can see that most of the requests get stuck in one of 2 places: com.objectdb.o.PGC:w: line number 232 com.objectdb.o.LFL:U: line number 1068 Please see the attached callgraph examples for full stack trace examples. ... edit delete natmaclin ... edit delete support ...

BIRT Driver Improvements

Currently the ObjectDB BIRT driver has the following limitations that should be fixed: It works with Eclipse 3.6 and BIRT 2.6 but not with Eclipse 3.7 and BIRT 3.7. It is bound to a specific ObjectDB version that it contains. ... edit delete support ... edit delete quasado ...
