The Microsoft DRDA Service can't process a dynamic SELECT statement from an IBM Java Client for DB2. Additionally, the Client returns the following error message:

The transaction operation cannot be performed because there are pending requests working on this transaction.

An internal error occurred during: "Retrieving object counts".


This issue occurs because the Microsoft DRDA Service incorrectly processes IBM Java Client for DB2 dynamic SQL SELECT statements when the DRDA Client is SQLAM (SQL Access Manager) Version 11.


This issue is fixed in Cumulative Update 2 for Host Integration Server 2016.


Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
