something about iterating from end of the collection to the start.

IBM Knowledge Center[^]:

-c | /c

Execute command following the -c option in a new DB2 command window, and then terminate. For example, db2cmd -c dir causes the dir command to be invoked in a new DB2 command window, and then the DB2 command window closes.

-w | /w

Execute command following the -w option in a new DB2 command window, and wait for the new DB2 command window to be closed before terminating the process. For example, db2cmd /w dir invokes the dir command, and the process does not end until the new DB2 command window closes.

objProcStartInfo = new ProcessStartInfo("db2cmd.exe", "-c -w -i db2 connect to " + strMasterdatabaseName + " user " + strserviceAccountUserName + " using " + strserviceAccountPassword + "&db2 -f " + strexportFilePath + " > " + strexportLogFilePath + "");
