Internal Exception and Index Problems

Dear Support Team, we have an urgent issue in a productive database. The objectdb doctor finds no error but one string field of one database item is not editable (even not using the objectdb explorer). The corrupt entry is in entity "UserModelData" with id="7d29d5eb-69a6-4d46-9bf1-802cbb6e439b". Try to change the userName attribute of this entry then the following error occurs: ... exception (Error 990) Generated by Java HotSpot(TM) Client VM 1.7.0_25 (on Windows 8 6.2).

Difficulty with the BIRT plugin

Hi, am trying to get the BIRT plugin to work. Firstly: connecting to an odb server doesn't seem to work (incompatible versions) - but there isn't any way to find out what version the BIRT plugin is using. Next: connecting directly to a file datasource seems to work, in the sense that I can ping the database, however, there doesn't appear to be any way to create a new Data Set from the Data Explorer, as suggested in the online manual: ...

Server crash - Mismatch client-server protocol prefix

We've been having a problem where our ObjectDB server goes unresponsive every 2 days or so.  I've reviewed the server-side logs, and there are no events logged shortly before the crash.  Once the server gets in this state, it is unresponsive to bin/server.sh restart; I have had to reboot the entire server on which it's running.  The only recorded symptom is a client-side error (which fortunately gets auto-mailed to me): ... it's running.  The only recorded symptom is a client-side error (which fortunately gets auto-mailed to me): [ObjectDB 2.5.2] javax.persistence.PersistenceException Mismatch client-server protocol prefix (error 523) at ... by: com.objectdb.o.UserException: Mismatch client-server protocol prefix at com.objectdb.o.MSG.d(MSG.java:61) ...

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.

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. ... password = "pwd" / > <client - truststore path = "$objectdb/ssl/client-tstore" password = "pwd" / > < / ...
