Re: Weird Error - CPF3E01 - DDM parameter value not supported. (using Db2 Connect driver for .NET Core)

I thought of that because the error occurs at a particular row# and I didn't see how big the data structure was.

I took a look at the "DDM Architechure Reference " (at https://www.ibm.com/support/knowledgecenter/SSEPH2_14.1.0/com.ibm.ims14.doc.apr/ims_ddm_cntqry.htm). Code points within DDM are identifiers for commands, command objects, other resources. I searched for x'2156' and found it is a parameter for the CNTQRY command (x'2006'). The parameter is

QRYROWSET
An optional parameter that specifies the number of rows of data to
return in one network reply. The number of rows is specified as a
4-byte binary number. The minimum value for QRYROWSET is 0. The
maximum possible value is 32 767. The codepoint for QRYROWSET is
X'2156'.

Maybe something is setting this parameter to 1192?

Doesn't seem to hit any limits I'm aware of...
Unless DDM is more limited than JDBC...
