Subject [jira] Commented: (DERBY-1219) jdbcapi/checkDataSource.java and jdbcapi/checkDataSource30.java hang intermittently with client
Date Tue, 09 May 2006 22:32:05 GMT
    [ http://issues.apache.org/jira/browse/DERBY-1219?page=comments#action_12378767 ] 

Deepa Remesh commented on DERBY-1219:
-------------------------------------

I am thinking along slightly different lines. The restart processing is doing some cleanup
and reloading the driver. Should'nt we wait for the reload to happen before we start working
on the new session which comes in? In that case, we will need some logic to check if a restart
is in progress before we add a new thread/session to the lists.

Or do we expect the driver to be reloaded by the time the new thread/session gets ready to
do the real work?

> The tests checkDataSource.java and checkDataSource30.java 
> hang intermittently especially with jdk 1.5.
> Attached is the test run output and traces when the server is started separately.
> 1) Enable checkDataSource30.java by taking it out of functionTests/suites/DerbyNetClient.exclude.
> 2) Run the test with client.

jdbcapi/checkDataSource30.java
> Attachements:
>  testfiles_after_hang.zip - Test directory.
>  traces_on_hang.txt  - Server side traces obtained by starting the server separately
before running the test.
> I wish I had time to work on this right now as I would really like to see this valuable
test in the suite, but hopefully someone else will pick it up.
