Get Current Publish Transaction

I was struggling a while back to retrieve the current Publish Transaction from template code. This is the Publish Transaction that is currently being executed in the Publisher. I needed it to identify who sent the current item to publish and with which priority. I found out it wasn't easy to retrieve the current Publish Transaction. In fact, it was impossible to identify it with absolute certainty.

I tried looking at the Publishing Queue and pick the transaction 'In Progress' or with status Rendering. However, this doesn't work reliably due to possible concurrent rendering threads or even multiple Publishers, so it is impossible to know for sure which exactly is the current Publish Transaction.

Then the following hack came to light thanks to a post by Chris Summers. And what a hack it is indeed: take the Binary storage path of the RenderInstruction and extract the Publish Transaction TCMURI from it.

The Binary storage path looks something like C:\Temp\tcm_0-164479-66560.Content\Binaries, so I can apply a Regular Expression to it to extract the TCMURI.

public PublishTransaction GetPublishTransaction(Engine engine)
    String binaryPath = engine.PublishingContext.PublishInstruction.RenderInstruction.BinaryStoragePath;
    Regex tcmRegex = new Regex(@"tcm_\d+-\d+-66560");
    Match match = tcmRegex.Match(binaryPath);

    if (match.Success) {
        String transactionId = match.Value.Replace('_', ':');
        TcmUri transactionUri = new TcmUri(transactionId);
        return new PublishTransaction(transactionUri, engine.GetSession());

    return null;

In the meantime, I filed an enhancement request on this topic.

Thanks for sharing Mihai - this just saved my ass. I have no idea where that post of mine was (I have little recollection of it), but I had certainly forgotten this trick.

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

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: I stumbled upon the following post from 2008 (!!!), , 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

Event System to Create Mapped Structure Groups for Binary Publish

As a continuation of last week's Publish Binaries to Mapped Structure Group , this week's TBB is in fact the Event System part of that solution. Make sure you do check out the previous post first, which explains why and what this Event System does. To reiterate, the Event System intercepts a Multimedia Component save, take its Folder path and create a 1-to-1 mapping of Structure Groups. The original code was written, again, by my colleague Eric Huiza : [ TcmExtension ( "MyEvents" )] public class EventsManager  : TcmExtension {     private Configuration configuration;     private readonly Regex SAFE_DIRNAME_REGEX = new Regex ( @"[\W_]+" );     public EventsManager() {         ExeConfigurationFileMap fileMap = new ExeConfigurationFileMap ();         fileMap.ExeConfigFilename = Path .GetDirectoryName( Assembly .GetExecutingAssembly().Location) + "\\EventSystem.config" ;         configuration = ConfigurationManager
