Bug 1305056

@maciejs, I've assigned to you as the Command Class (org.guvnor.asset.management.backend.command.CreateBranchCommand) is in guvnor and I'm at a loss why org.jbpm.executor.impl.AbstractAvailableJobsExecutor may be failing to find it (I recall we had some issues with different instances of AbstractAvailableJobsExecutor needing different DataSources, but AFAIK we only have one "out of the box"?). Would you mind taking a look?

two questions:
- is there kie server deployed to the same server?
- can we get complete stack trace?

Hi Maciej,

- is there kie server deployed to the same server?

I am checking it with customer. But in my tests it is deployed to the same server. It is easy to reproduce.

- can we get complete stack trace?
I have attached the logs generated from my tests.

Thanks in advance!

the reason why it fails is because you have both brms and kie server configured with same data base and thus kie server might executor pick up jobs submitted by brms. 

In general kie server and business central should not share db due to that exact issue. So there are two options:
- if you don't use kie server undeploy it
- if you use kie server, configure it with different data base (via different data source)

do you mind verifying that since you can easily reproduce it?

Maciej,

After undeploying the kie-server, it worked well.

Is it a bug? Should I keep these BZs opened?

Thanks!

it is not a bug as kie server should not use same db but leave it open I'll enhance asset mgmt processes to include owner id so only executor from workbench will be able to pick these jobs.

Maciej, this happens with *out of the box* configuration, which imho is a bug. If you are saying that kie-server.war and business-central.war should not use the same database, then let's make sure our product is not configured out-of-the-box with the same database.

For example, we could ship following in a standalone.xml:


                <datasource jndi-name="java:jboss/datasources/KieServer" pool-name="KieServerDS" enabled="true" use-java-context="true">
                    <connection-url>jdbc:h2:mem:kieServer;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE</connection-url>
                    <driver>h2</driver>
                    <security>
                        <user-name>sa</user-name>
                        <password>sa</password>
                    </security>
                </datasource>

And then change this line [1]:

        persistenceProperties.put("javax.persistence.jtaDataSource", config.getConfigItemValue(KieServerConstants.CFG_PERSISTANCE_DS, "java:jboss/datasources/ExampleDS"));

with
persistenceProperties.put("javax.persistence.jtaDataSource", config.getConfigItemValue(KieServerConstants.CFG_PERSISTANCE_DS, "java:jboss/datasources/KieServer"));

And of course, document this behavior in product doc.

Cheers,
Anton

Anton,

engineering is not providing installer so it's out of my controller. If you like to have this please create BZ for installer.

asset mgmt processes have been altered to make sure only same instance that created it will process them in background so it fixes that kie server will pick up these jobs
