> Key: DERBY-4863
> URL: https://issues.apache.org/jira/browse/DERBY-4863
> Project: Derby
> Issue Type: Bug
> Components: Network Server
> Affects Versions: 10.6.2.1
> Environment: windows 7, jdk 1.5.0_22, derby 10.6.2.1
> Reporter: Florin Herinean
> Attachments: StatementTimeout.java
>
>
> Derby update statements do not timeout until the (write) locks are released.
> The scenario involves 2 threads starting 2 separate transactions/connections,
> each of them attempting to update the same row. The first thread starts the
> transaction, locks the row (via update) then waits 40 seconds. The second
> thread is started 5 seconds later and it has a 5 seconds timeout set on the
> statement. Upon attempting to update the same row as the first thread, it
> times out after 35 seconds (40 - 5) and not after the expected 5 seconds as
> specified in the statement timeout.
> A test case is attached.
> Oracle and DB2 behaves as expected.
