Right, I overlooked that aspect. Still I think you can get access to
the Oracle connection intercepting the Connection creation in a
different place. The trick is to use the following PoolManager
constructor in the factory:
public PoolManager(ConnectionPoolDataSource, int, int, String,
String)
and for ConnectionPoolDataSource do something like this:
// subclass DriverDataSource to intercept connection creation
DriverDataSource driverDS = new DriverDataSource(jdbcDriver,
dataSourceUrl) {
public Connection getConnection(String userName, String password)
throws SQLException {
OracleConnection c = super.getConnection(userName,
password);
c.setEndToEndMetrics(...);
return c;
}
}
ConnectionPoolDataSource poolDS = new PoolDataSource(driverDS);

Andrus,
We are pursuing this idea, but unfortunately it seems that the
connection
object returned from the wrapped data source (in this case, the
wrapped data
source is a PoolManager) is a ConnectionWrapper object. I can't find a
method in that class to retrieve the native OracleConnection to be
able to
call the 'setEndToEndMetrics' method on it.
Any ideas?
Thanks,
Daniel

This approach (custom DataSourceFactory, that instantiates a
DataSource wrapper that in turn would call 'setEndToEndMetrics' on
every returned connection) is applicable for your case as well.

P.S. Custom DataSource is a solution to like 80% of the environment
integration problems. Probably need to write a detailed article on
that under the user guide at http://cayenne.apache.org/doc/
customizing.html

Hi,
In our project GLIN we would like to have a debugging mechanism
and hence
would like to pass user object or userID to be passed into the
connection as
a parameter, this can be done using the method setEndToEndMetrics
in =
oracle.jdbc.OracleConnectionWrapper. But I do not find a way in
Cayenne's
implementation where I can set these metrics into the
setEndToEndMetrics
method. I appreciate if I get some sort of hint or resolution for
the same.
