We're looking for some help with a UniOLEDB problem. I'm hoping someone can provide some input on the error.
We are currently developing a web application that uses UniOLEDB to execute SQL statements in UniData. Our code is in C# and is running as a service (single threaded). We have test case of 12 or so SQL statements that execute one after the other for a defined number of times. In otherwords the 12 statements are execute over and over for 20 times. Note the 12 statements are not dynamic so they are the same exact query each time, with no variations in data possible. What we are experiencing is a random points in the test we receive an E_FAIL condition. Sometimes it is on iteration 3 and sometimes it is on iteration 19 and sometimes somewhere else. As seen in the DRITrace log segements below there seems to be a pattern in the log of a thread change. When the problem occurs it is preceded by a change in the pattern. Also it looks as if UniData executes the query fine the error is when the data is coming back up the pipe. Check the log segments below. Finally we are using a UniOLEDB version just delivered by IBM, but prior versions also had the problem. The current version we are using is 1.4.5. The UniData version is 6.0.12. Normal set of thread changes occur and there is no error condition around this change. Note there is a change after uci::SQLFreeStmt entries. The next change occurs shortly after after a CAr, CDR log entry combination. uci::SQLFreeStmt(4100808) 00093900 uci::SQLFreeStmt(4100808) 00093901 uci::SQLFreeStmt(4100808) 00093902 THREAD CHANGED: New thread ID=5676(162c) 00093902 CArCommand(120200068)::~CArCommand() 00093903 CDRImCommandUCI::~CDRImCommandUCI 00093904 THREAD CHANGED: New thread ID=1832(728) 00093904 IDBPropertiesImpl(121732620)::GetProperties 00093905 DBPROP_CONNECTIONSTATUS 00093906 DBPROP_CONNECTIONSTATUS: Again we get a thread change in the same pattern as the last one.
