Re: [castor-dev] Pb with loadConfiguration while using simultaneously two databases

[Ralf Joachim]

Sylvie,
we are aware of problems with multiple database configurations at JDO2 
as this has been reported at bugs 1742 and 1865. Also bugs 1781 and 1865 
relate to different issues of creating JDO2 instances.

I have started to work on this some days ago but don't have a patch 
available yet as I need to discuss some concepts with Werner and Martin 
first.

For your specific problem can you please send me a short test case. I'll 
 have a look at it this evening and try to create a patch for your 
specific problem.

Regards
Ralf

Werner,
The file jdo-conf.dtd contains this:
<!ELEMENT jdo-conf ( database,transaction-demarcation ) >
and doesn't support many database element.
So, How can I do?
Sylvie.

Sylvie,
I actually don't know whether we really support two separate JDO
configuration files or not, but can you please try to move the two
<database> definitions into one configuration file, if this is an option
to you. Apart from this, there's a bug report out there that does not
match your problem 100%, but the resolution of which might address your
problem partially.
Regards
Werner

Betreff: [castor-dev] Pb with loadConfiguration while using
simultaneously two databases

Hi,
I've just integrated Castor 0.9.6 in my application.
I'm using two distinct database accesses (2 databaseFileConfig, 2 database
names).
But when I try to initialize the JDO objects like this:
JDO2.loadConfiguration(databaseFileConfig1,loader);
JDO2 jdo1 = JDO2.createInstance(nomDatabase1);
JDO2.loadConfiguration(databaseFileConfig2,loader);
JDO2 jdo2 = JDO2.createInstance(nomDatabase2);
I've have an exception on the second loadConfiguration.
In fact, after looking for the problem, I have to call
JDOConfLoader.deleteConfiguration();
To reset private static boolean _loaded to false, before calling the new
JDO2.loadConfiguration(..).
But is this ok, or may I have other pb later in my transactions ?

I have the same pb using the old JDO object (getDatabase() is calling
loadConfiguration(..)) :
JDO jdo1 = new JDO();
Jdo1.setClassLoader(loader);
Jdo1.setDatabaseName(nomDatabase1);
Jdo1.setConfiguration(databaseFileConfig1);
Database db1 = jdo1.getDatabase();
JDO jdo2 = new JDO();
Jdo2.setClassLoader(loader);
Jdo2.setDatabaseName(nomDatabase2);
Jdo2.setConfiguration(databaseFileConfig2);
Database db2 = jdo2.getDatabase();
Thanks for your help.
Sylvie
