[ http://issues.apache.org/jira/browse/DERBY-1090?page=all ]
Olav Sandstaa updated DERBY-1090:
---------------------------------
Attachment: brokeredlogical1090.diff
This patch (brokeredlogical1090.diff) implemets support for Connection.isValid
for pooled and XA connections.
Testing of isValid for pooled and XA connections is implemented in the
jdbc4/ConnectionTest.junit. This test is currently not part of either the jdbc4
suite or derbyall.
svn status reports:
M java/engine/org/apache/derby/iapi/jdbc/BrokeredConnection40.java
M
java/testing/org/apache/derbyTesting/functionTests/tests/jdbc4/ConnectionTest.java
M java/client/org/apache/derby/client/am/LogicalConnection40.java
I have run the jdbc4/ConnectionTest.junig, the JDBC4 test suite and derbyall
with the patch. Only failure was in tools/derbyrunjartest.java.
The patch can be reviewed and committed.

> The Javadoc for JDBC4 says this about Connection.isValid:
> boolean isValid(int timeout) throws SQLException
> Returns true if the connection has not been closed and is still valid. The
> driver shall submit a query on the connection or use some other mechanism
> that positively verifies the connection is still valid when this method is
> called.
> The query submitted by the driver to validate the connection shall be
> executed in the context of the current transaction.
> Parameters: timeout - - The time in seconds to wait for the database
> operation used to validate the connection to complete. If the timeout period
> expires before the operation completes, this method returns false. A value of
> 0 indicates a timeout is not applied to the database operation.
> Returns: true if the connection is valid, false otherwise
