Daniel John Debrunner commented on DERBY-1025:
----------------------------------------------
I wonder if the problem you are seeing may be due to this code in DRDAStatement:
/**
* Get prepared statement
*
* @return prepared statement
*/
protected PreparedStatement getPreparedStatement() throws SQLException
{
if (ps instanceof BrokeredPreparedStatement)
return (PreparedStatement)(
((BrokeredPreparedStatement)
ps).getStatement());
else
return ps;
}
This code, for some unknown reason due to lack of comments, is getting the
underlying embedded statement
from a BrokeredPreparedStatement. This should not be allowed, the
BrokeredStatement wrappers are there to
hide the embedded statement object as it can change under the covers of the
wrapper.
It could be that the network server is getting the prepared statement and then
hanging on too long and performing
actions on the wrong object. Though it seems unlikely that auto-commit on a
connection would go through the
prepared statement.
I wonder why this code needs the inner statement
> [xa] client XAResource.start() does not commit an active local transaction
> when auto commit is true

> Embedded XAResource.start() implementation commits the active local

> connection is auto-commit mode.
> Client incorrectly throws an XAException with the XAER_RMFAIL error code (see
