Subject [jira] Commented: (OPENJPA-1565) QueryTimeOut and LockTimeOut exceptions are not raised correctly
Date Tue, 16 Mar 2010 16:44:27 GMT

    [ https://issues.apache.org/jira/browse/OPENJPA-1565?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12845984#action_12845984
] 

Pinaki Poddar commented on OPENJPA-1565:
----------------------------------------

1. Note the SQL Error State and Code of the SQL Exception when it fails to throw expected
exception
2. Check sql-error-state-codes.xml for that database dictionary. The error states are categorized
in that file. If the observed error does not occur in the list of error states, add it (the
error state not the error code).
3. Also check corresponding DB dictionary implementation isFatalException() and ensure that
it returns false when query/lock timeouts are intended to be raised. 
4. Returning false from isFatalException() will ensure that at facade level the transaction
is not rolled back.

> Narrowing SQL Exception to a more specific exception such as lock or query or referential
integrity violation does not distinguish correctly whether a query or lock request has timed
out. 
> This distinction is critical for JPA 2.0 spec compliance because QueryTimeOut and LockTimeOut
exceptions are not supposed to cause rollback as per the spe (Section 3.9).
