Hi Everybody:

I'm Oscar Flor employee of Sebaot Software Your Customer.

We have experiencing performance problems in our Customers, then we did the tracing process of our Firebird Database.

In this task we have noticed that using IDBAC an error occurs when we open a DataSet.

Attached we provide a test program with database included that start the Firebird Trace Utility using el first button. Then have a second button to open/refresh the dataset. Since then in the trace we see a "request synchronization error" error message.

The problem is that error occurs many times multiplied by every user (almost 50 of them) using the database in the same time. Thats generate a lot of error messages on the log.

We notice that error does not raise a exception on our application and we use the DBMonitor tool You provide Us, and this error does not appear.

The question is. Is normal that this error occurs when we open a DataSet? Can be ignored or We must have do some work in our application to make this error disappear?

Thank you very much for you response.

To make this test program to work need to execute the platform You installed the Firebird Database (x86 or x64). The trace execution configuration file is generated by the program when is started.

Anyone knows how to upload a test case and two images? I have no a public HTML page to publish them.

Please, send your sample to viktorv*devart*com. Also, specify the FireBird version you are using.

Mr. Viktor:

I send TODAY the mail that is about 30MB of attachment. (There is inside a small test database plus test programs)

We have received your sample. We will investigate it and inform you about the results.

Thank You for you time, Mr. Viktor!

We have investigated this problem, and we assume it is not due to any bugs in IBDAC, but it is related to Firebird functionality issues. There are similar error reports in the Firebird bug-tracker. Anyway, this error mustn't affect IBDAC performance. We will continue investigation of the problem and inform you as soon as we get any results.

Understand!

Thank You Again Mr. Viktor

Feel free to contact us if you have any further questions about IBDAC.
