Deployer settings - max size and polling timeout

Question

I am getting the issue Polling for notification for destination: has exceeded polling attempts for transaction

What is the max setting I can use in the httpupload web.config?

• maxRequestLength
• maxAllowedContentLength

Also, in the cd_deployer_conf, what is the suggested timeout for polling? Is there a max?

Answer 1

The maximums are different units, strangely - one is kilobytes, and the other is bytes!

 <?xml version="1.0"?>
   <configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0">         
        <system.web>
            <!-- This value is in **kilobytes** -->
            <!-- http://stackoverflow.com/questions/4548305/maximum-value-of-maxrequestlength (See the answer by Petr - not the accepted answer) -->
<!-- 2097151 kilobytes = 2.09715 GB --><httpRuntime executionTimeout="1200" maxRequestLength="2097151" useFullyQualifiedRedirectUrl="false" minFreeThreads="8" minLocalRequestFreeThreads="4" appRequestQueueLimit="100"/>
        </system.web>

        <system.webServer>
            <security>
            <requestFiltering>
                <!-- This is the value in **bytes** -->
                <!-- 524288000 bytes = 500MB -->
                <!-- The maximum for this is 4,294,967,295 (3.99GB) - http://stackoverflow.com/questions/4022434/-->
                <requestLimits maxAllowedContentLength="524288000" />
            </requestFiltering>
            </security>
        </system.webServer>    
    </configuration>

I'm not sure about the maximum timeout for the polling. However, in addition to the web.config settings above, you may also need to add a MaxSize attribute to the HTTPSReceiver element in your cd_deployer_conf.xml configuration file:

< HTTPSReceiver MaxSize="2147483648" Location="C:\Program Files\Tridion\incoming" InProcessDeploy="true"/ >

To the first question you asked, below is my understanding:

The maxRequestLength specifies the maximum file upload size supported by the application/service, whereas the maxAllowedContentLength specifies the maximum length of the content in a request supported by IIS Web Server.

To deal with large transport package size, we need to set both maxRequestLength and maxAllowedContentLength in the web.config - if the values are different, the attribute having smaller value takes the priority
