Unable to Read Server Response

RB 10.06 server / Delphi 2007 / IIS 6.0 patched current

I'm getting a number of worker process failures for the application pool
that the web tier DLL is running in.

Are there specific settings I should use for IIS 6? What is causing the
worker process failures?

Thanks - Jon Gray

Have not had any other reports of this.

Try looking the WebTier log. You can also try setting
WebTier.LogSettings.Verbose to True to produce a more detailed log.

An IIS Worker Process is the windows process that is hosting the dll. A
quick Google search produced this link.

Here is an rbWiki article on How to Deploy to IIS6

I see you are using RB 10.06, I recommend updating to RB 10.09, which was
the last produced release for RB 10.x. You can also try downloading a trial
version of RB 11.08 and perform the same test.

Always make sure your report server and webtier and are compiled with the
exact same RB version.

Thanks for this - I am getting an AV reported in the webtier log file.

Is there an easy way to track down where the AV is coming from?

You can try using Delphi to run the WebTier within the context of a Delphi
Web Debugger application. That enables the Delphi debugger to be used in the
standard way.

An example of a Web Debugger application is installed to
RBServer\Demos\WebTier\Web Debug

I upgraded to RB 10.09 and the A/V problem persists.

I'm not able to set WebTier.LogSettings.Verbose to true. When I do I'm
not able to write to the log file. This is the error -

Please notify your system administrator of this problem.
Click here to proceed to your original destination.<<

The WebTier runs fine other than the sporadic A/V which does end up
written to the ($Application)\Logfiles log file.

I'm not able to identify what permission or setting I'm missing to get
the verbose setting to work properly.

Any help on how to get the verbose setting to work would be appreciated.

rbuser

I'm guessing this is related to the permissions somehow -

In addition to not being able to set verbose logging my cache
ISAPI/Cache folder is not clearing itself.

I'm running IIS 6

The only difference between WebTier.LogSettings.Verbose False vs True is the
amount of data logged. The logging feature is very simple, just writes some
xml to a file. If WebTier does not have security permisssion or the file is
locked by another appilcation, that would cause an issue. Have not heard of
either of these error before. In a a test here, I encountered no issues
using Verbose.

Try running of the demo report server and web tier projects included with RB
Server Edition to test whether that causes an issue.

You can also try running a webtier as a web debugger application - there is
an example installed with the RB Server Edition (Demos\WebTier\WebDebug).

I haven't been successful with the demo yet but I have another clue perhaps.

I'm doing some processing in the ReceiveAutoSearch fields call on the
client side. I call some oracle procedures to build a temporary table
that the report is run against.

Sometimes, even in normal processing, I get an oracle error back. I
report the error to the user, they make some corrections and try the
report again. Could it be something like this that has the web log
locked and/or why I'm getting some A/V? Almost as tho something isn't
being reset with multiple runs of the same report.

Delphi 2007 RB 10.09

I don't know why you are getting an AV, have not heard of this before and
cannot reproduce it here. I would try running the webtier as a Delphi web
app debugger project so you can trace the code.
