when I use
Diagnostics.Trace.WriteLine("message", "Information");
in my azure-asp.net this does not show up in my azure compute emulator,
but if I do the same from my worker-role it works, any idea why?
Thanks!
This is with SDK 1.3, right? In 1.3, web roles by default run with full IIS, which means your actual web app code is in a different app domain from your RoleEntryPoint. I believe the compute emulator only shows messages from RoleEntryPoint (WebRole.cs or WorkerRole.cs).
To double check, try putting a trace message in OnStart in WebRole.cs; I'm guessing it will show up.
Add a TraceListener of the type :
Microsoft.ServiceHosting.Tools.DevelopmentFabric.Runtime.DevelopmentFabricTraceListener,
Microsoft.ServiceHosting.Tools.DevelopmentFabric.Runtime,
Version=1.0.0.0,
Culture=neutral,
PublicKeyToken=31bf3856ad364e35
The reason is due to not having this TraceListener in the AppDomain of the ASP.NET application - which is different to where WebRole.cs runs. All changed in v1.3 with the introduction of full IIS.
http://blog.bareweb.eu/2011/01/tracing-to-azure-compute-emulator-sdk-v1-3/
Use Trace.TraceInformation instead:
Writes an informational message to the trace listeners in the Listeners collection using the specified message.

There was a failure executing the send pipeline:

but the schema namespace is "http://schemas.microsoft.com/Sql/2008/05/TableOp/dbo/User1"
and the select node is : SelectQuery
after deploying make restart for host instance and nothing changed.
The problem is the message that hit's the Pipeline does not match any Deployed Schemas. So, this error is only a symptom of the real problem, it is not a problem in itself.
First, "SelectQuery" is not a valid WCF SQL Element. Do you mean Select/Query?
Next, it look like the schema was generated twice and you're using the wrong one. I can tell because of "User1".
So, figure out which is the right one, User or User1. Then make sure that is the one that's user where you expect and that it's deployed.
This probably isnt an issue with SiteCore per se but I've included it for completeness. I have sitecore 6.3 running under IIS7 using a custom identity for the app pool. I cant get Sitecore to write its logging information (using the default log4net settings) to the eventlog. I've followed the advice here: http://logging.apache.org/log4net/release/faq.html#Why%20doesn%27t%20the%20EventLogAppender%20work? and although it works fine when I make the custom identity a member of the administrator's group I need to find a way to get it working in production without such a security hack.
The weird thing is that I have a MSI that installs it (running under an account which IS a member of the administrator's group) and creates the correct registry keys in the eventlog for me and yet despite that, I am still getting the following error when I run the application using the custom identity (without it being a member of administrators).
log4net:ERROR DOMConfigurator: Could not create Appender [EventLogAppender] of type [log4net.Appender.EventLogAppender]. Reported error follows.
System.Security.SecurityException: Requested registry access is not allowed.

at log4net.Repository.Hierarchy.DOMHierarchyConfigurator.ParseAppender(XmlElement appenderElement)
The Zone of the assembly that failed was:
MyComputer
log4net:ERROR DOMConfigurator: Appender named [EventLogAppender] not found.
Thinking I could narrow it down to a registry permission issue I granted Everyone full permissions to the following registry key and subkeys but it didnt work either: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\eventlog
The custom identity is a member of the following groups:
Event Log Readers
IIS_USERS
Performance Monitor Users
I've also seen the following question which seems to ask the same thing. The Microsoft article seems to suggest it might be a problem with ACLs on an event log and gives examples on how you can change SSDLs but I'd rather avoid that if at all possible.
EDIT:
I have another server running where the log is being populated fine. The custom identity was a member of administrators so I revoked that and rebooted, trying to purposely break it but I cant. Config is identical on both boxes and same identity used to run the MSI which creates the registry keys. Have run procmon on both (after doing a IISReset and spinning up the app pool again) to examine registry activity. Strange thing is - on the box that works you get 477 name not found records for my event source in the wrong places (Application, and a different Custom EventLog "MyCompany"). No hits for the place where it is logging which is "MyCompany\MyCompany.SiteCore". Whilst on the box which is broken, it does appear to be requesting to read the right key (albeit only 6 times) but you then get the Log4Net registry access error.
As I understand it EventStores are stored in the registry, so you only need write permission to registry to create or delete an EventStore. This is usually only needed once and most applications create this as part of the install procedure so that the application does not need to be run as Administrator during normal execution.
However your error message (in the question) includes the method DeleteEventSource from which I would deduce/guess that the EventSource does exist but is wrong in some way. So perhaps this is currently registered as writing to the event log named MyCompany and you are now trying to change it to "MyCompany\MyCompany.SiteCore" which requires you to delete the old eventsource and create a new one.
So it sounds like your installation routine is creating a different EventSource from the one that your application is actually using.
If that doesn't help, then I would suggest enabling internal logging for Log4net (but obviously not to the eventlog) which will probably give you more information.
Giving full permission to the registry key is not enough.
According to Microsoft
To create an event source in Windows Vista and later or Windows Server 2003, you must have administrative privileges.
The reason for this requirement is that all event logs, including security, must be searched to determine whether the event source is unique. Starting with Windows Vista, users do not have permission to access the security log; therefore, a SecurityException is thrown.
Starting with Windows Vista, User Account Control (UAC) determines the privileges of a user. If you are a member of the Built-in Administrators group, you are assigned two run-time access tokens: a standard user access token and an administrator access token. By default, you are in the standard user role. To execute the code that accesses the security log, you must first elevate your privileges from standard user to administrator. You can do this when you start an application by right-clicking the application icon and indicating that you want to run as an administrator.
I think, contrary to the Apache documentation, log4net DOES need write access to the registry – or at least it does in my case. To prove this, I backed up the registry on the server where it wasnt working and granted IIS administrator privileges before spinning up sitecore. Sure enough it started logging away to the eventlog nicely and then when I exported the registry again to run a diff, there WAS a difference.
The value for the eventlogmessage file on my event source had been updated from:
C:\Windows\Microsoft.NET\Framework\v2.0.50727\EventLogMessages.dll
To
C:\Windows\Microsoft.NET\Framework64\v2.0.50727\EventLogMessages.dll
So I assumed that merely changing this value in the registry by hand would work.
But it didn’t.
So I ran procmon on the two servers I have: A=the working one, B=the failing one. Sure enough, on server B I have a line which says:
Operation: RegOpenKey, Path: HKLM\System\CurrentControlSet\Services\EventLog, Desired Access:Read/Write, Result: ACCESS DENIED.
I’ve traced through with Server A and in exactly the same place, the key is requested with Desired Access:Read.
Conclusion:
It seems unavoidable that I will need to grant my app pool identity administrator privileges in production for at least enough time to programatically do the necessary registry writes the first time from within log4net. I dont know why administrator; I have tried granting Full permissions to the entire eventlog node in the registry for my custom app to no avail. It seems to do something which I cannot identify or pin down. I will then revoke this privilege immediately after it starts to log and monitor whether subsequent installs knock out the functionality afterwards. (Hopefully not).
If anyone has any insight into this behaviour it would be greatly appreciated.
I have a flex application that communicates via BlazeDS with two webapps running inside a single instance of Tomcat.
The flex client is loaded by the browser from the first webapp and all is well. However on the initial call to the second webapp the client receives the following error:
Detected duplicate HTTP-based FlexSessions, generally due to the remote host disabling session cookies. Session cookies must be enabled to manage the client connection correctly.
Subsequent calls to the same service method succeed.
I've seen a few posts around referring to the same error in the context of two flex apps calling a single webapp from the same browser page, but nothing which seems to help my situation - so I'd be very grateful if anyone could help out....
Cheers, Mark
Three potential solutions for you:
I found once that if I hit a remote object before setting up a messaging channel then the CientID would get screwed up. Try to establish an initial messaging channel once the application loads, and before any remote object calls are made.
Flash Builder's network monitoring tool can cause some problems with BlazeDS. I set up a configuration option on application load that checks to see if I'm in the dev environment (it is called just before setting up my channel from #1). If I'm in dev, I assign a UID manually. For some reason this doesn't take well outside the dev environment... been awhile since I set it all up so I can't remember the finer points as to why:
if (!(AppSettingsModel.getInstance().dev))
FlexClient.getInstance().id = UIDUtil.createUID();
BlazeDS by default only allows for a single HTTP session to be setup per client/browser. In my streaming channel definitions I added the following to allow for additional sessions per browser:
<channel-definition id="my-secure-amf-stream" class="mx.messaging.channels.SecureStreamingAMFChannel">
<endpoint url="https://{server.name}:{server.port}/FlexClient/messagebroker/securestreamingamf"
class="flex.messaging.endpoints.SecureStreamingAMFEndpoint"/>
<properties>
<add-no-cache-headers>false</add-no-cache-headers>
<idle-timeout-minutes>0</idle-timeout-minutes>
<max-streaming-clients>10</max-streaming-clients>
<server-to-client-heartbeat-millis>5000</server-to-client-heartbeat-millis>
<user-agent-settings>
<user-agent match-on="MSIE" kickstart-bytes="2048" max-streaming-connections-per-session="3" />
<user-agent match-on="Firefox" kickstart-bytes="2048" max-streaming-connections-per-session="3" />
</user-agent-settings>
</properties>
Problem: Duplicate session errors when flex.war and Livecycle.lca files are hosted in separate JVMs on WebSphere Server.
Solution:
Inside the command file for the event, set FlexClientId to null in execute method before calling remote service (Java method or LC Process).
Guess this approach can be used in other scenarios as well to prevent Duplicate session errors.
EventCommand.as file
—————————–
import mx.messaging.FlexClient;
//other imports as per your code
public function execute(event:CairngormEvent):void
{
var evt:EventName = event as EventName ;
var delegate:Delegate = new DelegateImpl(this as IResponder);
//***set client ID to null
FlexClient.getInstance().id = null;
delegate.functionName(evt.data);
}
Background: I'm calling a Web Service written in ASP.NET that queries an Oracle database. I know the Web Service itself works, because I've used it before other applications. So I have a web application in Visual Studio that I've been switching back and forth to point from a 'DEV' web service to a production configured version of the same web service for testing. Pointing to the 'DEV' configured web service is no problem, but calling the production version I always get an exception calling the service:
SoapException was unhandled by user code
Server was unable to process request. ---> could not execute query
[ SELECT this_.FIELD1 as FIELD1_18_0_, this_.FIELD2 as FIELD12_18_0_ FROM ABC.TABLE_A this_ WHERE this_.FIELD1 like :p0 ORDER BY this_.FIELD1 asc ]
Positional parameters: #0>00073%
[SQL: SELECT this_.FIELD1 as FIELD1_18_0_, this_.FIELD2 as FIELD12_18_0_ FROM ABC.TABLE_A this_ WHERE this_.FIELD1 like :p0 ORDER BY this_.FIELD1] ---> ORA-12571: TNS:packet writer failure
I ran the SQL queries against the appropriate database (cut and pasted straight out of the exception message) and the query came back with the expected data. I've tried updating and re-adding the Web Service reference both as a "Service Reference" (.NET 3.0+ way) and as a "Web Reference" (Older .NET way), and both give the same error.
Question: So, what does a "ORA-12571: TNS:packet writer failure" error mean in the context of a Web Service? Looking up the Oracle Error number gives some very vague possible causes such as "loose cable connection" or "IP address conflict". I'm fairly certain it's neither of these, since a different application is currently successfully using that Web Service. Possibly some kind of configuration error, or maybe something more subtle? Anyone else seen this vexing Oracle error number being attributed to something web-service related?
Your call is going from the ws client to the ws server to the oracle database.
Your error is an ORA error, which is generated by the database. So your problem is probably between the ws server and the database.
When you ran "the SQL queries against the appropriate database", did you do it from the web server? If not could you try that. Make sure that you are using the same connection configuration.
EDIT
As per the comment below, the real problem was a driver mismatch.
I would suggest re-examining your assumptions more carefully, as this is clearly an error in the web-service dialogue with the db and should be completely independent of the w/s caller.
If the w/s call is generating this specific exception, it should be doing so for all other invocations, so your 'other application' that's using the web service successfully is simply not executing the same code or there are outside factors at play.
Either way, it's unrelated to how the service is registered or invoked.
Our site is currently having this problem. Basically it only happen when we click some particular links where it will pop-up a new window.
This is the error message we receive :
Unable to make the session state request to the session state server.
Please ensure that the ASP.NET State service is started and that
the client and server ports are the same. If the server is on a
remote machine, please ensure that it accepts remote requests by
checking the value of
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\aspnet_state\Parameters\AllowRemoteConnection.
If the server is on the local machine, and if the before
mentioned registry value does not exist or is set to 0, then the state
server connection string must use either 'localhost' or '127.0.0.1' as
the server name. target site : Void
MakeRequest(StateProtocolVerb, System.String, StateProtocolExclusive,
Int32, Int32, Int32, Byte[], Int32, Int32, SessionNDMakeRequestResults
ByRef)
this is the webconfig that contain sessionstate tag :
<sessionState mode="StateServer" timeout="45" />
I have check the ASP.NET State Service, and it is currently started and set to automatic
I have set the registry stated in the error message to 1, but still not working.
Start–> Administrative Tools –> Services
Right-click on the ASP.NET State Service and click “start”
Additionally you could set the service to automatic so that it will work after a reboot
If you need to change HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\aspnet_state\Parameters\AllowRemoteConnection to 1, remember to restart the ASP.net state service after you change the parameter.
Check that:
stateConnectionString="tcpip=server:port"
is correct. Also please check that default port (42424) is available and your system does not have a firewall that is blocking the port on your system
Type Services.msc in run panel of windows run window. It will list all the windows services in our system. Now we need to start Asp .net State service as show in the image.
Your issue will get resolved.
One of my clients was facing the same issue. Following steps are taken to fix this.
(1) Open Run.
(2) Type Services.msc
(3) Select ASP.NET State Service
(4) Right Click and Start it.
Another thing to check is whether you have Windows Firewall enabled, since that might be blocking port 42424.
I've had the same issue when some ASP.NET installation was corrupted. In that case they suggest running aspnet_regiis -i -enable
I've found that some developers will for some reason define the server's private IP outside of IIS in an unexpected location, like a nonstandard config file (i.e. not web.config) or a text file. This can cause internal operation to fail even when the service is started, ports aren't being blocked, reg keys are correct, etc.
Kaseya, in particular, places a file called serveripinternal.txt in the root IIS directory of the VSA server. I've seen the text of your error when somebody running their own Kaseya instance changed the server's internal IP. The server will be reachable, IIS will respond, and the login page will come up - but login will fail with the cited message.
Not the best answer, but it's an option anyway:
Comment the given line in the web.config.
I recently ran into this issue and none of the solutions proposed fixed it. The issue turned out to be an excessive use of datasets stored in the session. There was a flaw in the code that results in the session size to increase 10x.
There is an article on the msdn blog that also talks about this.
http://blogs.msdn.com/b/johan/archive/2006/11/20/sessionstate-performance.aspx
I used a function to write custom trace messages to measure the size of the session data on the live site.
