Hello All,
I have been working on a user issue and they are hitting a disconnect
error. The server is disconnecting the client connection. Client is
sending a CNTQRY, the server is receiving it and then server disconnects
the client. When I start the server, after a while, I see the message
agentThread[DRDAConnThread_4,5,main].
Further debugging, this message gets printed out because of the
agentError that is thrown in splitQRYDTA.
The error seems to come from this part of the code in splitQRYDTA, It
hits the temp.length==0 case.
private void splitQRYDTA(DRDAStatement stmt, int blksize) throws
SQLException,
DRDAProtocolException
{
// make copy of extra data
byte [] temp = writer.copyDSSDataToEnd(blksize);
// truncate to end of blocksize
writer.truncateDSS(blksize);
if (temp.length == 0)
agentError("LMTBLKPRC violation: splitQRYDTA was " +
"called to split a QRYDTA block, but the " +
"entire row fit successfully into the " +
"current block. Server rowsize computation " +
"was probably incorrect (perhaps an off-by-" +
"one bug?). QRYDTA blocksize: " + blksize);
stmt.setSplitQRYDTA(temp);
}
In doneData and writeFDODTA, it looks like if (writer.getDSSLength() >=
blksize) , then the splitQRYDTA is called. From testing, it seems like
they are hitting an edge case, where the writer.getDSSLength() is equal
to blksize and this DSS is the only dss in the send buffer. Can someone
confirm if this is possible ?
Thanks much,
Sunitha.
