Tridion Event System Timeout

问题

I am currently running Tridion 2011 SP1.

I am writing some code that runs whenever a page is published. It loops through each component template in the page, gets the component and writes out various fields to an XML document. For pages with many component templates or components with many fields this process can take a while to run. If the process takes more than 30 seconds I get an error

The operation performed by thread "EventSystem0" timed out.

Component: Tridion.ContentManager
Errorcode: 0
User: NT AUTHORITY\NETWORK SERVICE

followed by another

Thread was being aborted.


Component: Tridion.ContentManager
Errorcode: 0
User: NT AUTHORITY\NETWORK SERVICE

StackTrace Information Details:
   at System.RuntimeMethodHandle.InvokeMethod(Object target, Object[] arguments, Signature sig, Boolean constructor)
   at System.Reflection.RuntimeMethodInfo.UnsafeInvokeInternal(Object obj, Object[] parameters, Object[] arguments)
   at System.Delegate.DynamicInvokeImpl(Object[] args)
   at Tridion.ContentManager.Extensibility.EventSubscription.DeliverEvent(IEnumerable`1 subjects, TcmEventArgs eventArgs, EventPhases phase)

I believe I have three options.

1. Increase the timeout

This seems like a lazy solution and only hides the problem. There is no guarantee that the timeout problem won't reoccur. I'm also not sure where the timeout value is stored (I've tried changing a few values in the Tridion Content Manager.msc snap-in but no luck).

2. Do less in the actual event handler routine and have a separate process do all the hard work

This doesn't seem like the correct solution either. I would really like to keep all my event handler code in the one place. We have a solution like this in place for our live 5.3 installation and is a nightmare to maintain (it is very old and poorly written).

3. Make my code more efficient

My components have many fields and my code must delve deeper into each field if they are ComponentLinks. I guess because the properties of Tridion objects are lazy loaded there is one call to the API/database for each property I access. It takes on average 0.2 seconds to retrieve a property which soon stacks up when accessing multiple properties. If there was a way to retrieve all properties in one call this would be useful.

Any ideas?

回答1:

Have you considered running your event asynchronously? You can do this by changing the following line:

EventSystem.Subscribe<IdentifiableObject,TcmEventArgs(....)

EventSystem.SubscribeAsync<IdentifiableObject,TcmEventArgs(....)

回答2:

One thing you might consider doing is using the Component's .ToXml() method and get your values from the XML DOM instead of using the Tridion API. This is usually considerably faster, and you can use XSLT or Linq to "walk" through your fields.

If you are really only interested in fields, then just use the .Content (and .Metadata) properties and, again, use Linq or XSLT or whatever technology you want to parse the xml (except RegEx perhaps).

You are simply doing a lot of processing and that takes time. Maybe there's a technical fix, but the first thing to do in this situation is to go back to Why and What? Publishing a page is fundamentally about rendering the HTML and binaries that you want to output for that page. How long should that take?

So please could you tell us why you are doing this? Perhaps part of the effort can be moved somewhere else without compromising on good design. If we know what the purpose is, perhaps we can help more.

SDL Customer Support have advised that I increase the timeout. While not a great solution its the only one that is available. To do this

On the server that the content manager is installed open the Tridion.ContentManager.config which should be located in the config/ subdirectory of the Content Manager root location, which defaults to C:\Program Files\Tridion\ or c:\Program Files (x86)\Tridion\
Find the <eventSystem> node
Increase the threadtimeout value (this is in seconds) to something higher (I put it to 120)
Save the Tridion.ContentManager.config and restart the Tridion Content Manager Service Host service

Further documentation is available http://sdllivecontent.sdl.com/LiveContent/web/pub.xql?action=home&pub=SDL_Tridion_2011_SPONE&lang=en-US#addHistory=true&filename=ConfiguringEventSystem.xml&docid=concept_48C53F76CBFD45A783A3975CA72ECC49&inner_id=&tid=&query=&scope=&resource=&eventType=lcContent.loadDocconcept_48C53F76CBFD45A783A3975CA72ECC49. It does require a username and password to access.

If you really need the processing time then I think you should write a web service that performs the actions you need, which you can call from the event handler. This would not influence user experience (in the case of a synchronous event handler) as much either.
