[Hibernate] ubermq?

[Viktor S. <phr...@im...>]

hi,

i came across UberMQ on sf.net (http://sourceforge.net/projects/ubermq), 
it seems to be a nice jms implementation, but what puzzled me was this 
quote: "Several open-source projects have already embraced UberMQ as 
their messaging platform of choice, including Hibernate" (see 
http://www.ubermq.com/products.html)... i can't see where hibernate 
needs a message queue implementation... would someone enlighten me? :)

best regards,
    viktor

[Hibernate] Docu update and instructions

[Christian B. <chr...@bl...>]

I just commited the following files:

* New documentation generation instructions, including scripts

* Hibernate style configuration for PDF and XSL

* Updated HTML and PDF documentation, using the new scripts and the
  Wiki CSS

Gavin, redirecting the site is your part. If everythings working out
fine, I will cleanup the documentation directory a bit more and remove
the old pages and unused images and so on...

BTW: The DocBook toolchain is really very painful...

Re: [Hibernate] Re: slow performance on flush

[Juozas B. <ba...@ce...>]

It is no standard way to for this trick, It depends on RDBMS implementation.
It is possible upload tab separated text file to server and execute  native
SQL on postgersql like this:
"COPY mytable FROM filename "
http://www.postgresql.org/idocs/index.php?sql-copy.html

Re: [Hibernate] Re: slow performance on flush

[Christoph S. <ch...@mc...>]

Hey!

The stuff you mention sounds cool, and I already thought about that, but to
my knowledge there's no java api that supports stuff like that. If you know
a api that supports such functionality, please tell me, that would be really
great!

Re: [Hibernate] Re: slow performance on flush

[Juozas B. <ba...@ce...>]

It is better to use some "native" API like "COPY" for long running import,
some RDBM's support imports without constaint
checks, SQL parsing ....  , and sometimes "long running import" becomes very
"short".

I have a really long running import, and I want to write the records to the
db as they come in. Is it save to clear the entries Map after a flush? Or
would you recommend a different approach?

  Yup, all entries are kept in the session cache until you close the
session. Why would you use this kind of code?? Just flush() once at the end
(outside the loop).

    Hi all!

    I'm trying to increase the performance of this pseudocode:

    for (j=1;j<100;j++)
    {
        for (i=1;i<100;i++)
        {
            session.save(class)
        }
        session.flush();
        session.connection().commit();
    }


    Now my problem is that flush doesnt take a constant time, but every
invocation of flush takes more time than the last one, the more I flush the
slower it gets. To me it looks like hibernate keeps the references to the
flushed objects in the entries map, and doesnt remove them. Is there
anything I can do about it?

    regards
     chris

Re: [Hibernate] How to create an index on normal property element ?

[Gavin K. <ga...@ap...>]

Yick!

<property name="ownernumber" type="string" >
      <column name="ownernumber" length="50" not-null="true"
index="index_name"/>
</property>

but it looks like the property isn't really called "ownernumber"; perhaps
you meant "ownerNumber"?

Re: [Hibernate] How to create an index on normal property element ?

[Jochen R. <joc...@si...>]

Thanks for your help, but exactly in the line with the colum  tag (corresponds to line 15)  the schema generator shows an error: 

<property name="ownernumber">
     <column name="ownernumber" type="string"  length="50" not-null="true" index="index_name"/>
</property>


Any ideas ???

Kind regards

Since everyone should be in the process of upgrading to version 1.2 ;) you

[Hibernate] How to create an index on normal property element ?

[Jochen R. <joc...@si...>]

I have the following hibernate-mapping definition for "Friend" : 

<class name="buddy.database.Friend" table="friends">
  		<id column="friends_key" name="key" type="long">
      		<generator class="native"/>
    	</id>
    	<set role="meetings" lazy="true" table="participants">
        	<key type="long" column="friends_key"/>
            <many-to-many class="buddy.database.Meetings" column="meetings_key"/>
       	</set>
    	<property name="name" 	     column="name" 			type="string"  	length="50"/>
    	<property name="number"      column="number" 		type="string" 	length="50" not-null="true"/>


<!-- I want to index this element: ownernumber to speed up some queries :  -->
    	<property name="ownernumber" column="ownernumber" 	type="string"  	length="50" not-null="true"/>


    	<property name="active"   	 column="active" 		type="boolean" 	length="50" />
        
  	</class>  




In Mysql I have to add this line manually (after running the Schema generator) :

create index ownerindex on friends (ownernumber);



As I see in the DTD there is no way to specify an index for a normal property, am I wrong ?



<!ELEMENT property (column*)>
  <!ATTLIST property name CDATA #REQUIRED>
  <!ATTLIST property type CDATA #IMPLIED>
  <!ATTLIST property column CDATA #IMPLIED>
  <!ATTLIST property length CDATA #IMPLIED>
  <!ATTLIST property not-null (true|false) "false">
  <!ATTLIST property unique (true|false) "false">


Thanks for any help, Hibernate is great !

[Hibernate] Re: slow performance on flush

[Gavin K. <ga...@ap...>]

Just use a new Session for each loop iteration. It is even possible in a =
special case like this to have multiple sessions in the same JDBC =
transaction.=20

for ( int i=3D0; i<100; i++) {
    Session s =3D sf.openSession(conn);
    for ( int j=3D0; j<100; j++) {
        s.save( ... );
    }
    s.flush();
    s.close();
}
conn.commit();

However I suspect in this case you are better off doing it in multiple =
transactions....

      Hi all!

      {
          for (i=3D1;i<100;i++)

      Now my problem is that flush doesnt take a constant time, but =
every invocation of flush takes more time than the last one, the more I =
flush the slower it gets. To me it looks like hibernate keeps the =
references to the flushed objects in the entries map, and doesnt remove =
them. Is there anything I can do about it?

    for (i=3D1;i<100;i++)
    {
        session.save(class)
    }
    session.flush();
    session.connection().commit();
}


Now my problem is that flush doesnt take a constant time, but every =
invocation of flush takes more time than the last one, the more I flush =
the slower it gets. To me it looks like hibernate keeps the references =
to the flushed objects in the entries map, and doesnt remove them. Is =
there anything I can do about it?

I'm selfishly designing the build script to make it as convenient as
possible for _me_ to do a binary file release from CVS. You should be able
to accommodate different needs by setting build properties.

Re: [Hibernate] Multi-table classes?

[Gavin K. <ga...@ap...>]

At this stage I'm not planning anything beyond the <joined-subclass> mapping
strategy. Theres plenty of workarounds ... you could create a data-holder
class with a one-to-one association to the containing class, for example.

Again, great features!

I'm improving the documentation again with a new stylesheet in the Wiki
layout (we should release that when the site is switched over) and also
improve and document the documentation build process: We now use Saxon 
(Xalan doesn't work well with the current DB-XSL) and don't require any 
additional packages or stylesheet files aside from the DocBook 
distribution files (using parrameters properly now).

I will commit a README for the build process and shell scripts later today.

[Hibernate] 1.2 rc1

[Gavin K. <ga...@ap...>]

I will be releasing a new version real soon (the next day or so - just doing
some extra testing now). The highlights are:

* MUCH more mature support for normalized mappings :)
* support for scalar values in queries called with find()!
* support for component-valued properties in select clause
* more natural semantics for query language expressions like: not
foo.bar.baz = 'foo'
* support for subcollections in query langugage: foo.bars[2]['index'],
foo.bars[4].elements, foo.bars[0].size, etc.
* new calandar + calendar_date types

It would be nice if some of you guys could try out the current CVS HEAD over
the next 24 hours, as a check that nothings broken and that new
functionality is working as expected.

Re: [Hibernate] RE: [Xdoclet-user] Xdoclet, Middlegen and Hibernate

[Gavin K. <ga...@ap...>]

This is a very cool idea and I'm happy to give whatever support is necessary
on this end. (In particular, we need to update the hibernate XDoclet module
to reflect the new mapping DTD so I will take care of that.) However, I'm
not an expert with XDoclet and I've never used middlegen, so my usefulness
will be somewhat limited.

[Hibernate] RE: [Xdoclet-user] Xdoclet, Middlegen and Hibernate

I'm willing to participate in this effort. Matt are you seriously
interested in a middlegen-hibernate module?

Hi!

Sorry for cross-posting. Please continue hibernate related discussions
over
in hib...@li.... If it's Middlegen related,
crosspost to mid...@li....

The best way to use Middlegen (http://boss.bekk.no/boss/middlegen/) with
Hibernate would be to use a similar approach as CMP. Middlegen could
generate the java beans with @hibernate tags.

Then you let XDoclet generate the hibernate-mapping.xml with Hibernate's
XDoclet module. Hibernate maintains their own XDoclet module in the CVS
module named Tools.

It doesn't look like the Hibernate folks are including their XDoclet
module
in their distro, but you'll find it here:
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/hibernate/

The hibernate tags:
http://tinyurl.com/2z2v

Who wants to write a Hibernate plugin for Middlegen?

Cheers,
Aslak

Would someone please grab a CVS update and run FooBarTest and MultiTableTest
on Oracle 9 and confirm that they are both now working....

TIA

[Hibernate] RE: [Xdoclet-user] Xdoclet, Middlegen and Hibernate

[<asl...@ne...>]

Hi!

Sorry for cross-posting. Please continue hibernate related discussions over
in hib...@li.... If it's Middlegen related,
crosspost to mid...@li....

The best way to use Middlegen (http://boss.bekk.no/boss/middlegen/) with
Hibernate would be to use a similar approach as CMP. Middlegen could
generate the java beans with @hibernate tags.

Then you let XDoclet generate the hibernate-mapping.xml with Hibernate's
XDoclet module. Hibernate maintains their own XDoclet module in the CVS
module named Tools.

It doesn't look like the Hibernate folks are including their XDoclet module
in their distro, but you'll find it here:
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/hibernate/

The hibernate tags:
http://tinyurl.com/2z2v

Who wants to write a Hibernate plugin for Middlegen?

Cheers,
Aslak
