8 | Updating Entities queries since simply constructing this top level class will take many hours/days to do given |
8 | alter table.Doctor old.odb new.odb Besides, I've stocked more than an hour, after the above command for a 10GB |
8 | Should I use ObjectDB and JDO? several years with Objectdb. I have also spent many, many hours over many years comparing DBMS |
8 | Speed of queries that return many objects one is about 4GB. So in the end - loading the DBs takes hours. Thanks EKK Emmanuel Keskes Unfortunately |
8 | Wrong data stored in date only fileds/10/2015 Madrid time (when clock goes back 1 hour at 3am), Object DB puts wrong data in the fields |
8 | 100% CPU when using multiple BETWEEN regards Emil prolancer Emil Andonov Thanks. Download is very slow and could take many hours |
8 | find repeated records by JPQLHi, I know a single command in MySQL can find repeated records: Select * from TTT t where id in (select id from TTT s group id having count(id)>1) I dont know how to do this using JPQL, but I use query from 430,000 records and put them into hashmap, finally it cost one hour and failed |
1 | Server out of memory exceptions haven't been able to reproduce it consistently though as it worked ok for a hour on a subsequent rerun |
1 | Exception makes the system unusable for several minutes, we can see that always the same objects (around 4) are in charge. A doctor we cannot do currently as it takes around 6-8 hours |
1 | Once served to JSF page via @EJB query bean, many list fields are null (but same query ok after fresh persist in @PostConstruct) against my real-world project that works with EclipseLink, and it has once again taken many hours |
