Oracle 10G and JBPM 3.1.1 Issues

[kazam]

Hi there,

Following the documentation, I generate the scripts for oracle and they execute nicely both oracle.create.sql and oracle.drop.sql.

However, the tests are failing.
Library : classes12.jar from Oracle10g database.
Hibernate Dialect: Oracle9Dialect

I have made the following change as mentioned in the jbpm-starters-kit-3.1.1/jbpm-db/readme.html

modify jbpm.3/src/resources/hibernate.cfg.xml: add line
<property name="hibernate.query.substitutions">true 1, false 0</property>

However, the testresults have a success rate of 1.5% with no failures but 262 errors out of 266 tests.

Below I am providing some part of the output of the ant oracle.test target.
Where can I post or upload the entire ant target log file.

I would really appreciate if someone who has successfully done this can help me out.

Thanks,Kazam.

Kazaam,
If you send me your email address I can send you a copy of our internal wiki, which contains the instructions we used to get the starter kit up and working with the Oracle database.
Everything went well for us there, except there were two tests that failed, mainly due to bad test procedure, one was referrring to the old hibernate database, and another to a missing class.
It should contain pretty detailed instructions for you.

Here's a line from our wiki that may help:
When this completes, you can examine detailed reports on all the tests by loading jbpm-db/build/oracle/testfiles/index.html in your web browser.

When I first ran the test, I got lots of errors back due to a missing C3P0 module. This is explained on the JBOSS site. (http://jboss.com/index.html?module=bb&op=viewtopic&p=3932199)

Running this test on the JBPM starter kit, we find three errors. One is a class not found error which seems to result from a bad configuration file specifying a non-existent class, and the other two are in the org.jbpm.graph.exe.SuspendAndResumeDbTest class, apparently due to a hard-coded reference to the Hypersonic SQL DB, when in fact we're testing against Oracle.

Maybe that will help some.

Thanks James,
I appreciate your help. Please take a look at my profile for the email address, I have also sent you an email.
I would get back once I try adding the cp30 jar or taking it out.
Thanks Again,
Kazam.

James,

We are always interested in taking back your enhancements if you e.g. worked around this hard coded reference to Hypersonic. Also, if the info is not secret, why not publish the Oracle migration instructions on the jBPM wiki as well?

Regards,
Koen

I am working on some of the stuff now, trying to get everything all cleaned up and usable.

Has this been published to the wiki yet... (the steps for setting up on oracle)
The date on the previous post looks to be newer that what is in the wiki. :)

I'm wanting to setup jBPM on an Oracle AS 10.1.2 with an Oracle 10g DB.
Each webapp would have the jBPM jar and supporting jars (hibernate) bundled with it.

What are all the different types of deployments for jBPM?
Is the EJB wrapper still an option? we may need clustering later on.

Also, I noticed in the JSF console webapp for 3.1, there were a lot of warnings for using the deprecated method JbpmSession(Session). Is this
going to be updated soon?

Is it typical to have one jBPM DB 5 different webapps, or would you / could you setup different jBPM DB's for each webapp?

Thanks,
Chad

After following the docs, I can generate the scripts for oracle10g, and the scripts run fine in oracle.

Currently, ant oracle.test achieves 98%, w/only 4 errors.

My question is as why does it the test keep running the SchemaExport, etc. on hsqldb? Here are to snippets of the output indicating loading the oracle information from hibernate.properties and then using C3P0 using the hsqldb driver?

Any suggestion or pointers would be greatly appreciated.

I noticed in kazam's post the C3P0 connection used the oracle driver. Any thoughts?

Thanks,
