Get All ApplicationData with Given ID

Did you know that in Tridion 2011SP1 it is now possible to retrieve all items that have a particular Application Data ID associated? This method basically allows you to search for a given Application Data ID and it returns the TCMURIs of all items that have that AppData ID associated.

This topic would have been very useful when I developed the AppDataInspector Powertool. At that time, in Tridion 2011GA, this functionality was not available. I would have liked to be able to search for a given Application Data ID. Instead, the tool only reads AppData on the 'current' item. [Note to self: add "search by id" functionality to AppDataInspector]

Core Service
You can use Core Service method: ICoreService2011.GetSubjectIdsWithApplicationData

Gets a list of TcmUri of subjects which have application data of the specified applicationId associated.
Namespace: Tridion.ContentManager.CoreService

The sample below is taken from my Core Service Client blog post:


public string GetSubjects(string appDataId)
{
    var result = "";

    foreach (var uri in _client.GetSubjectIdsWithApplicationData(appDataId))
    {
        result += uri + ", ";
    }

    return result;
}



TOM.NET
You can use the following method: SystemManager.GetSubjectIdsWithApplicationData(string id)

Gets a list of TcmUri of subjects which have application data of the specified applicationId associated.
Namespace: Tridion.ContentManager



var result = "";
var systemManager = session.SystemManager;
foreach (var uri in systemManager.GetSubjectIdsWithApplicationData("ugc:ComponentAndPage"))
{
    result += uri + "; ";
}

Running sp_updatestats on AWS RDS database

Part of the maintenance tasks that I perform on a MSSQL Content Manager database is to run stored procedure sp_updatestats . exec sp_updatestats However, that is not supported on an AWS RDS instance. The error message below indicates that only the sa  account can perform this: Msg 15247 , Level 16 , State 1 , Procedure sp_updatestats, Line 15 [Batch Start Line 0 ] User does not have permission to perform this action. Instead there are several posts that suggest using UPDATE STATISTICS instead: https://dba.stackexchange.com/questions/145982/sp-updatestats-vs-update-statistics I stumbled upon the following post from 2008 (!!!), https://social.msdn.microsoft.com/Forums/sqlserver/en-US/186e3db0-fe37-4c31-b017-8e7c24d19697/spupdatestats-fails-to-run-with-permission-error-under-dbopriveleged-user , which describes a way to wrap the call to sp_updatestats and execute it under a different user: create procedure dbo.sp_updstats with execute as 'dbo' as

Content Delivery Monitoring in AWS with CloudWatch

This post describes a way of monitoring a Tridion 9 combined Deployer by sending the health checks into a custom metric in CloudWatch in AWS. The same approach can also be used for other Content Delivery services. Once the metric is available in CloudWatch, we can create alarms in case the service errors out or becomes unresponsive. The overall architecture is as follows: Content Delivery service sends heartbeat (or exposes HTTP endpoint) for monitoring Monitoring Agent checks heartbeat (or HTTP health check) regularly and stores health state AWS lambda function: runs regularly reads the health state from Monitoring Agent pushes custom metrics into CloudWatch I am running the Deployer ( installation docs ) and Monitoring Agent ( installation docs ) on a t2.medium EC2 instance running CentOS on which I also installed the Systems Manager Agent (SSM Agent) ( installation docs ). In my case I have a combined Deployer that I want to monitor. This consists of an Endpoint and a

Debugging a Tridion 2011 Event System

OK, so you wrote your Tridion Event System. Now it's time to debug it. I know this is a hypothetical situtation -- your code never needs any kind of debugging ;) but indulge me... Recently, Alvin Reyes ( @nivlong ) blogged about being difficult to know how exactly to debug a Tridion Event System. More exactly, the question was " What process do I attach to for debugging even system code? ". Unfortunately, there is no simple or generic answer for it. Different events are fired by different Tridion CM modules. These modules run as different programs (or services) or run inside other programs (e.g. IIS). This means that you will need to monitor (or debug) different processes, based on which events your code handles. So the usual suspects are: dllhost.exe (or dllhost3g.exe ) - running as the MTSUser is the SDL Tridion Content Manager COM+ application and it fires events on generic TOM objects (e.g. events based on Tridion.ContentManager.Extensibility.Events.CrudEven
