How to Create a Folder Structure with the Core Service?

This topic has been asked recently on StackOverflow. The question was how to create a Folder (or actually a series of nested Folders) like /aaa/bbb/ccc/ddd using the Core Service in Tridion 2011SP1?

The answer is you have to create each individual Folder as a sub-folder of an existing parent. This means the approach is very well suited to be handled with a recursive call.

I created a method called GetOrCreate(path) that checks if the path exists. If it does, it returns the FolderData object. Otherwise, it splits the path into a parent path and a new folder name and applies recursion on the parent path. On the way out of the recursion, the new folders are created as children of the (by now) existing parents.

private FolderData GetOrCreateFolder(string folderPath, SessionAwareCoreServiceClient client)
    ReadOptions readOptions = new ReadOptions();

    if (client.IsExistingObject(folderPath))
        return client.Read(folderPath, readOptions) as FolderData;
        int lastSlashIdx = folderPath.LastIndexOf("/");
        string newFolder = folderPath.Substring(lastSlashIdx + 1);
        string parentFolder = folderPath.Substring(0, lastSlashIdx);
        FolderData parentFolderData = GetOrCreateFolder(parentFolder, client);
        FolderData newFolderData = client.GetDefaultData(ItemType.Folder, parentFolderData.Id) as FolderData;
        newFolderData.Title = newFolder;

        return client.Save(newFolderData, readOptions) as FolderData;

Note: the method does not validate the folderPath. Rather, it expects it to be syntactically correct and its stem to represent a valid and existing Publication WebDAV URL.

Call this method using a construct like this:

    FolderData folderData = GetOrCreateFolder(
        "/webdav/020 Content/Building Blocks/aaa/bbb/ccc",
        new SessionAwareCoreServiceClient());

You cal also use a CoreServiceSession, as described in my earlier post.

I love being able to Google a Tridion question to find Yet Another example on your blog, Mihai. Definitely helped with some "folder export" code I wanted to try.

"Just say no" to manual folder creation!

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
