Subject [jira] [Commented] (DERBY-5338) When attempting to insert a 4GB stream client gives SQLState XN015 network protocol error vs embedded 22003 data too large for type
Date Tue, 09 Aug 2011 07:16:27 GMT

    [ https://issues.apache.org/jira/browse/DERBY-5338?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13081489#comment-13081489

Kristian Waagan commented on DERBY-5338:

There may be some relevant information in DERBY-2017 regarding exception handling.
I believe that we now have the tools needed to avoid raising a protocol exception (since Derby
10.6), but I don't know how much of the existing code that would have to be changed.

> In converting LobLimits test DERBY-1903, I see that attempting to insert a 4GB stream
with client gives the error XN015
> Caused by: org.apache.derby.client.am.SqlException: Network protocol error: the specified
size of the InputStream, parameter #4, is less than the actual InputStream length.

> vs's embedded's 22003, the length exceeds the maximum length for the data type.
> I am not sure if the connection is lost or not. It typically is with protocol errors.
> Look for this bug number in largedata.LobLimits.java for test case.
> You can remove the exclusion for usingDerbyNetClient and run org.apache.derbyTesting.functionTests.tests.largedata.LobLimitsLiteTest

> to reproduce the problem.  I will check the test case in soon as part of DERBY-1903
