Subject [jira] Closed: (DERBY-1239) Assign relevant errors to late-breaking new JDBC4 SQLException subclass: SQLRecoverableException
Date Mon, 12 Jun 2006 21:13:30 GMT
     [ http://issues.apache.org/jira/browse/DERBY-1239?page=all ]
     
Rick Hillegas closed DERBY-1239:
--------------------------------

    Resolution: Fixed

The semantics of this exception are unclear. It appears that this is extra support added for
Oracle. We can revisit this issue if the semantics become more clear.

> An upcoming jdk16 release will expose another new subclass of SQLException: SQLRecoverableException.
Here is the verbiage from the draft SQLException chapter of the next rev of the JDBC4 spec:
> ---------------------------------------------------------------------------------------
> 7.5.3 SQLRecoverableException
> A SQLRecoverableException would be thrown in situations where the failed
> operation might succeed if the application performs some recovery steps and retries
> the entire transaction or in the case of a distributed transaction, the transaction
> branch. At a minimum, recovery includes closing the current connection and getting
> a new one. After a SQLRecoverableException the application must assume that
> the connection is no longer valid.
> -------------------------------------------------------------------
> And here is the upcoming new javadoc header for this class:
> java.sql
> Class SQLRecoverableException
> java.lang.Object
>   extended by java.lang.Throwable
>       extended by java.lang.Exception
>           extended by java.sql.SQLException
>               extended by java.sql.SQLRecoverableException
> All Implemented Interfaces:
>     java.io.Serializable, java.lang.Iterable<java.lang.Throwable>
> public class SQLRecoverableException
> extends SQLException
> The subclass of SQLException thrown in situations where a previously failed operation
might be able to succeed if the application performs some recovery steps and retries the entire
transaction or in the case of a distributed transaction, the transaction branch. At a minimum,
the recovery operation must include closing the current connection and getting a new connection.
