Subject [jira] Commented: (DERBY-1219) jdbcapi/checkDataSource.java and jdbcapi/checkDataSource30.java hang intermittently with client
Date Mon, 15 May 2006 23:10:08 GMT
    [ http://issues.apache.org/jira/browse/DERBY-1219?page=comments#action_12402450 ] 

Bryan Pendleton commented on DERBY-1219:
----------------------------------------

I ran both tests multiple times on my Linux JDK 1.4.2 environment with no hangs, and tests
passed
each time. This particular machine was very reliable in reproducing the hang before, so I
think that's
a good result, and it confirms your result.

I would be glad to commit this patch. Do you think there are any other details we should check
first?

> 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.

> 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.
