Some third party backup products may by default restore CACHE.DAT files as UNIX sparse files when there are trailing zeroes in the backup file.

The support for sparse files vary from UNIX distribution and file system types.  Sparse files attempt to use file system space more efficiently when blocks allocated to the file are mostly empty similar to thin-provisioned storage.  The file system transparently converts metadata representing empty blocks into "real" blocks filled with zero bytes at runtime. The application is suppose to be unaware of this conversion.

Do you need to quickly build a web page to interact with your database? 

Take a look at these two courses to learn how Zen Mojo can help you display collections and make your collections respond to user interactions.

Displaying Collections and Using the Zen Mojo Documentation

Learn the steps for displaying a collection of Caché data on a Zen Mojo page, find crucial information in the Zen Mojo documentation, and find sample code in the Widget Reference. Learn More.

Hi,

I created an iKnow domain, where I supplied dictionaries, blacklist, metadata and stemming. The datasource is a table.

I would like to use iFind semantic search feature. It is said in the documentation that iFind use iKnow semantic analysis. But I want iFind to use the iKnow  domain configuration I created earlier earlier. How can I do that ?

Regards,

Jack Abdo.

Hi!

Is there any simple way to query data about processed messages in all Ensemble productions?
What I ultimately would like to do is to periodically export that data to another system and run statistics on it.

I've been digging around in the SQL tables view and Ens.MessageHeader seems to contain most of what I'm after.
Using ODBC I could access that table view and query data, but only for one namespace per DSN it seems.

The object and relational data models of the Caché database support three types of indexes, which are standard, bitmap, and bitslice. In addition to these three native types, developers can declare their own custom types of indexes and use them in any classes since version 2013.1. For example, iFind text indexes use that mechanism.

Is there a possibility to map a CSP page residing in namespace ABC to a namespace XYZ so you could access it as if executing from XYZ: http://localhost:57772/csp/xyz/MyPage.csp ? Some odd cocktail of web application and package mappings that could make this happen?

The idea is to keep the CSP page in sort of a read-only namespace that only contains code, with the data residing in another namespace. This works for zen pages, but not for CSP.

Oracle plans to deprecate the much-maligned Java browser plugin in JDK 9. For years, the bundled plugin put users at risk with its numerous security flaws. The web is clearly moving to a plugin-free state, which is a good direction.

If you are relying on the Java browser plugin, you should take a look at Java Web Start.

Here is the official blog post by Oracle:

This is a nice introductory explanation of MQTT that I thought would be of general interest. The technology used for the broker in this case is not that important as there are several brokers available.

At global summit we will be demonstrating ways to use MQTT with Ensemble to get information from the Internet of Things into your enterprise applications and business processes,

In some project, I found the need to use SMIME format https://www.ietf.org/rfc/rfc3851.txt, basically is an standard used to wrap a message together with its signature using a certificate (usually X509). Ensemble don't have a single class to do that but inside the Ensemble installation we have the openssl utility, so in this example I use the "openssl smime" command to sign or verify a message.

The example has two Business Process that able to sign or verify and in order to test I made a simple production.

Hope this helps

Announcing Deltanji 6.0, the latest version of the well-respected George James Software source control product formerly known as VC/m.

Deltanji comes in four editions, including Solo which is quick to install on Caché or Ensemble (2009.1 or later), easy to get started with, and perpetually free.

Deltanji runs within the environment whose code it is managing, integrating closely with Studio and Portal, and storing code versions in a CACHE.DAT database.

So calling this lookup manually from the console works as expected:

PHR>set key = "WMMC_IMM"
PHR>w ##class(Ens.Util.FunctionSet).Lookup("BlockFeed",key)
1

 

However, calling it from a method with some concatination to build the key is giving me problems:

I'm working on some custom utility functions that I can utilize in Business Rules as well as other places.  I saw this line in the docs:

For each function you wish to define, add a class method to your new function set class. There is no support for polymorphism, so to be precise, you must mark these class methods as final.

I have a routing rule that processes messages from multiple customers. I would like to create some sort of flag or setting that I can toggle to indicate if a given customer is allowed to pass messages through the router. Should I use a registry entry, lookup table or something else? Which can be accessed from a routing rule and how?

Hi,

I'm trying to create a Zen Report that, when rendered to PDF has a header on every page that includes some items from the group that I'm iterating over in the <body>.  I can't use <header> as that only displays once for each iteration, even if that spans more than one page, but <pageheader> seems to be independent of <body> so again doesn't work.

 

Cheers,

Steve.

When posting content there's got to be a better way to insert a screen shot. Saving to a file and then uploading is very primative plus the content isn't display in-line as one would expect these days. I don't want to "view a document" I want to see the image in-line.

Confluence does a really good job with this. Can we emulate this behavior?

I have a service named FTP_In that is of class EnsLib.HL7.Service.FTPService.   It picks up files from multiple subfolders and sends them to an EnsLib.HL7.MsgRouter.RoutingEngine.   What I want to do is somehow capture the subfolder as a variable for use in the routing rules.  Is this possible?

Let's say I have the following files and directory structure on my FTP Server

New to CSP and Zen.  I've been going through tutorials and have made some progress.  Using the "Contacts" tutorial as an example, I'm trying to create a "ViewContact" page.  I want this to be linkable so I'm using URI Parameters, which I understand.  However, what I'm not sure about is how to retrieve a specific record.  Should I use a SQL statement?  If so, how?
