This could influence the customer as well. Supposing not being just testing blocker. Setting blocker to ?.

Hi Ondra,

Which version of EAP 6.2 did you try this on and where can I download it from please?

Thanks,
Tom

Hi Ondra,

Wouldn't we need:
https://bugzilla.redhat.com/show_bug.cgi?id=971358

It doesn't look like stefano has resolved that yet?

Tom

OK, so I have had a look at this. The problem is that the JDBCstore caches the lookup of the datasource before calling getconnection. Assuming there isn't a performance issue with re-resolving the JDBC store every time we call getConnection I can change getConnection to lookup the datasource each time.

I have solved this in JBTM-1938

Hi Tom,

thanks for the fix.

From my point of view the bz
https://bugzilla.redhat.com/show_bug.cgi?id=971358
was fixed. But Stefano could have some more input on it. I'm not sure.

Ondra

So, having made the fix in the narayana repo,

For information: this has the same severity as 1011379, both are fixed in 4.17.11.

Michael Musgrove <mmusgrov> updated the status of jira JBTM-1938 to Closed

Verified on EAP 6.2.0.ER6. It's possible to reload server and no error messages are received on the console.

Hi,

I'm sorry I've found out that my previous statement is not true. 

The problem with reloading the server set with JDBC driver still occur in some cases. But there is a new error now. I'm running on EAP 6.2.0.ER6.

From the log it seems to me as a timing issue. Time to time the data source could be bound after the transactions subsystem is started.

Hi Ondra,

I think it is a different cause. The last issue was that the JDBC object store caches connections, this new issue seems to be related to there not being a dependency between the TM and JCA services (i.e. from a BZ point of view, this new issue could affect the initial load, not just a :reload)?

I will look further...

Tom

Hi Tom,

I agree this is different issue which is related to module dependency management in AS rather than to transactions subsystem.
Just to clarify the problem happens to me just after the reload. I didn't experience the problem after the initial load. But it could be a coincidence.

I will report this problem as a new bz and I will verify this one.

Thanks
Ondra

Verifying this issue.

I created new bugzilla as mentioned above.
