Re: AzMan Access Check

Dear Jeffrey,

Thanks for your reply!

After some more testing, we found out that when performing access check by
the mentioned APIs, it consume too much network resources. When I ran
netstat as the application was running, there were some thousands TCP
connection in TIME_WAIT state. Currently, my workaround is to decrease the
delay time to close the connection earlier, which in turn allow more
connection to the machine.

Is it possible to specify a connection to use with the AzMan Library? If so,
can you provide some references for it? I read from the MSDN there is no
similar topic on this, or I missed somethings?

Again, thanks for your help!

Best Regards,
Tony Cheung

Hi Tony,

Thanks for your feedback!

Yes, with my WinXP SP2 2G CPU 1G RAM machine, after running 5 applications
for a whole night, I finally got 0x0000003a "The specified server cannot
perform the requested operation" error in 4 applications, and Error
0x000004c9 "The remote system refused the network connection" in 1
application. They got the error after running for more than 2600 loops.

On my Win2003 SP1 3G CPU 2G RAM machine, after running 5 applications more
than 30000 loops, I still can not get any error result.

It seems this issue is cllient machine specific, because I am using the
same DC in my 2 tests. Based on my experience, the applications may used
out certain system on the client machine, most likely certain network
resources.

Because there is no coding issue in your application, I recommended you
improve your client system hardware to keep the problem from occurring,
this should be the simplest way so far. Additionally, you may introduce
certain recycle mechanism in your application just as Asp.net does, then
we
can always keep the loop count below the possible error limitation.
Finally, because this error exhibits mostly when we are running multiple
instances of the application, in production environment, I think it is not
easy for the end user to meet the limitation. Do you feel comfortable
regarding this? Anyway, please feel free to tell me your concern.

I hope my suggestion makes sense to you. Thanks!

Best regards,
Jeffrey Tan
