transactions - tempdb SQL Server locking -

-

Our application runs on a client machine with another application. We have made some attempts to avoid long-running locks in tempdb because this clearly affects the concurrency. Other applications, however, works like this:


Start the transaction # to create # tables (...); Insert into # tables (....) values ​​(...);
operation_for_totally_synx_second ()
committed;

As operations take time, our application is waiting for the lock received by other apps.

Now, I hope that there may be a way to separate my application from other applications, for example I have been asked to provide other tempi to SQL Server, but I have no way have been found. Is it any way possible or is there a solution to install our database on any other mssql-instance?

Long-lasting locks Tempdb This clearly affects solidarity

This is not really clear at all. Long-held locks are of importance only if you and other applications go after the same locale. The code sample you posted is completely valid. Firstly #temp is a connection specific table that no other connection can see. But even if this is a global resource, it will be related to other applications and therefore you will not have any business on it.

As an exercise, open an SSMS query window and run it: 

  Start the transaction; Create table #temp (an integer);

Then open another query window and run one. QED, they do not block each other, despite creating very #temp tables.

If tempdb is actually a bottle neck, then you need to check some more and need to find actual resources that are on dispute. / P>

c# - How to capture HTTP packet with SharpPcap -

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.
