TTCmd.Execute(TTStatus) return OK, but getRowCount() return 0.

Question

We have a critical 24/7 application that execute 1000 operations every 2 minutes on a TimesTen database.
Sometimes, an error occurs when we execute a statement previously prepared. To validate the execution we use a try/catch c++ block.
I transcribe the code below:
1 int DBConnection::insertCallDetailRecord (
2      scpTransIdType scpTransId,
3      callAttempStateType callAttempState,
4      billingStatusType billingStatus,
5      disconnectingPartyType disconnectingParty,
6      faultCodeType faultCode,
7      forceDCHType forceDCH,
8 bool doCommit,
9      ScpError **error )
10 {
11
12      try
13     {
14          cmdInsertCDR.setParam(1, callAttempState);
15          cmdInsertCDR.setParam(2, billingStatus);
16          cmdInsertCDR.setParam(3, disconnectingParty);
17          cmdInsertCDR.setParam(4, faultCode);
18          cmdInsertCDR.setParam(5, forceDCH);
19          cmdInsertCDR.setParam(6, scpTransId);
20
21          
22          TTStatus stat;
23          cmdInsertCDR.Execute(stat);
24          if (cmdInsertCDR.getRowCount() == 0)
25          {
26               scpError_setError(error, SCP_ERROR_TT_WARNING, DB_SQL_NO_DATA_FOUND, true, "En: %s() [%s, Linea %d] - Msg: Error al ejecutar '" #cmdInsertCDR ".Execute(stat)'. Err: %s",
27                    __func__, __FILE__, __LINE__, "0 registros insertados");
28               return -1;
29          }
30          if(doCommit)
31               Commit(stat);
32     }
33     catch (TTError &st)
34     {
35          if ( st.isConnectionInvalid() ) {
36               return DB_ERR_INVALID_CONNECTION;
37          }
38          else
39          {
40 TTStatus statRoll;
41 Rollback(statRoll);
42 scpError_setError(error, SCP_ERROR_TT_ERR, st.rc, true, "En: %s() [%s, Linea %d] - Msg: %s. Err: %d", __func__, __FILE__, __LINE__, st.err_msg, st.rc);
43 return -1;
44 }
45     }
46
47     return 0;
48 }
In line 23 we execute the statement, and no error occurs, so the flow of code continues.      
Then, in line 24 the method getRowCount() returns 0, and the error occurs.
It is very strange what happened, because the operation was successful but the method getRowCount() returns the value 0.
This occurs approximately every 10,000,000 of operations (insert, delete or update).
The application and database running on Sun Solaris 10, 64 bits.
We appreciate if someone who had a similar problem can help us.
Thank you very much.

Answer 1

Chris: thanks again for your reply. I Answer your questions below:
1. Version of TimesTen:
brunellr@scpasua> ttVersion
TimesTen Release 7.0.3.0.0 (64 bit Solaris) (tt70:17001) 2007-09-12T06:12:16Z
Instance admin: ttadm
Instance home directory: /home/ttadm/TimesTen/tt70
Daemon home directory: /home/ttadm/TimesTen/tt70/info
Access control enabled.
2. We confirm that when the problem occurs, the statement does not insert the row in database.
Best regards.
