[Hibernate-JIRA] Created: (HHH-4857) Sharing some of the config info from Ejb3Configuration and SessionFactoryImpl

by Chris Baxter (JIRA)

Sharing some of the config info from Ejb3Configuration and SessionFactoryImpl ----------------------------------------------------------------------------- Key: HHH-4857 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4857 Project: Hibernate Core Issue Type: New Feature Components: core, entity-manager Reporter: Chris Baxter Priority: Minor In our system, we have each clients data in a separate DB instance. We're using JPA (via hibernate) on top of that to get at the data. The problem here is that for each client DB supported by one of our jboss servers, we have to have an instance of EntityManagerFactory compete with an Ejb3Configuration instance. Each config instance takes up around 20 MBs of permanent space, so if we have have 1000 client DBs supported by a jboss instance, it takes up a hugh amount of memory for information that will always be the same (the DB schemas are always the exact same in each client DB) across all EntityManagerFactory instances. So what I want to know is if there is a way to only have one instance of Ejb3Configuration that can be shared across all of the EntityManagerFactory instances that are spawning my EntityManagers. This would be huge as it would help me save many gigs of memory that never can be collected (old gen in jboss). I prototyped some changes locally to Ejb3Configuration (to allow an instance of AnnotationConfiguration to be supplied in the constructor, allowing sharing across all instanced of this class) and to SessionFactoryImpl (to share some of the properties like entityPersisters, classMetadata and such) and I was able to reduce the footprint to 20 MBs for the first DB and then under a MB for each additional DB. The changes I made were a bit quick and dirty though, just to see if it was possible. So I'm taking out this feature request to see if this is a piece of work that you guys can do (or I can contribute after refactoring to a more suitable approach) and integrate into the main code for hibernate-core and hibernate-entitymanager. Let me know if this is something you guys think to be a valuable addition. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira

[Hibernate-JIRA] Created: (HV-477) Investigate how parameter and return value validation can be consolidated

by Gunnar Morling (JIRA)

Investigate how parameter and return value validation can be consolidated ------------------------------------------------------------------------- Key: HV-477 URL: http://opensource.atlassian.com/projects/hibernate/browse/HV-477 Project: Hibernate Validator Issue Type: Improvement Components: engine Reporter: Gunnar Morling Fix For: 4.x Currently there are some redundancies in the code for parameter and for return value validation ({{ValidatorImpl}}. Maybe it's possible to generify and unify the existing code and use it in both cases. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira

[Hibernate-JIRA] Created: (HHH-3465) HiRDB Support

by Tomoto Shimizu Washio (JIRA)

HiRDB Support ------------- Key: HHH-3465 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3465 Project: Hibernate3 Issue Type: New Feature Components: core Affects Versions: 3.2.5 Environment: 3.2.5 + HiRDB V8 + Type4 JDBC Driver Reporter: Tomoto Shimizu Washio Attachments: hirdbdialect.patch I would like to contribute with a dialect for HiRDB, Hitachi's RDBMS. (For more information, please see http://www.hitachi.co.jp/Prod/comp/soft1/global/prod/hirdb/) I added 4 classes and slightly modified 2 existing classes as shown below. Please look at the documentation at the top of the patch for explanations. org.hibernate.dialect.HiRDBDialect (added) org.hibernate.dialect.UserFuncDeclParser (added) org.hibernate.dialect.DialectFactory (modified) org.hibernate.dialect.function.AnsiTrimEmulationFunction (modified) org.hibernate.dialect.function.AnsiTrimEmulationFunctionWithTrimstrs (added) org.hibernate.dialect.function.TypeQualifiedSQLFunction (added) You may think this code is relatively large as a dialect. It is because I also implemented user-defined function support. As HiRDB requires '?' parameters to be qualified by 'as <type>' in user-defined function invocations, I made a parser for the type declarations that the user specified in the properties file, and a renderer for the type qualifier. See javadoc comments of HiRDBDialect and UserFuncDeclParser for more details. This patch is created on Hibernate 3.2.5.ga and tested on HiRDB V8 with Type4 JDBC Driver. The example configuration for HiRDB is shown below: hibernate.dialect org.hibernate.dialect.HiRDBDialect hibernate.connection.driver_class JP.co.Hitachi.soft.HiRDB.JDBC.HiRDBDriver hibernate.connection.url jdbc:hitachi:hirdb://DBID=@HIRDBENVGRP=C:/hirdb.ini hibernate.connection.username hitachi hibernate.connection.password hitachi -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
