It's well-known that namespace global mapping helps us to write code independent on database storage details (Caché instance name, directory path). But sometimes we can face problems accessing an unsubscripted global which has subscript level mapping (SLM) defined. Most of such cases are evident and associated with administrative tasks that should be done on database level, but some of them can confuse even an experienced developer. Just to start:

• We can't export such a global using Caché Block format (a.k.a. GOF).
• We can't kill such a global.

Maybe you can continue this list.

Each of these

Google Cloud Platform (GCP) provides a feature rich environment for Infrastructure-as-a-Service (IaaS) as a cloud offering fully capable of supporting all of InterSystems products including the latest InterSystems IRIS Data Platform. Care must be taken, as with any platform or deployment model, to ensure all aspects of an environment are considered such as performance, availability, operations, and management procedures.  Specifics of each of those areas will be covered in this article.

October 12, 2018 – Advisory: VMWare vSphere and Data Integrity

Clients running vSphere 5.5 or later should review a very important article that VMware published on October 9, 2018.  The article describes the possibility of file system and database corruption, which can lead to outages and possible data loss.  We have confirmed that this has caused data integrity problems for InterSystems clients. Therefore, we encourage you to act on this as soon as possible.

The VMWare knowledge base article is titled:

Hello,

I'm wondering what the path is to learning healthshare & ensemble?   I've looked on the learning page and its minimally helpful.   I've found that as a long time mumps programmer that new jobs are requiring this.  I've just been using mumps to assist with epic emr.   Everything I'm seeing is either VistA or Healthshare.  Does someone know where do I go to learn these apps?  Seems like a catch 22.  You need to know these prior to getting a job but you can't get a job where you can learn them.    Frustrating.

October 12, 2018 – Alert: Ordering of XML Sibling Elements

InterSystems has corrected a defect that can cause a reordering of sibling elements in an XML document. This issue is limited to sibling elements that are represented in the database as objects in a relationship.

This problem exists on all platforms for the following products:

• InterSystems IRIS Data Platform 2018.1.0 and above
• InterSystems IRIS for Health 2018.1.2
• Caché and Ensemble 2017.2.0 and above
• Health Connect/HSAP based on Caché/Ensemble 2017.2.0 and above

Note: HealthShare functionality has been reviewed and is not impacted by this

Is there any out of the box capability in Ensmeble to remove an FHS segment from a batch file? We have a client that is creating a batch of HL7 messages and they insert an FHS but there is no trailing FTS.

We are hoping to avoid custom COS code to handle this scenario.

Upgrade of custom application

Dear community,

we are a company located in central Germany working with Intersystems Caché since 2003 (Jesus, that's actually a long time in IT).

As we struggle to keep pace with outside development we still operate on Caché 2013.1

We are, of course, aware that we need to upgrade Caché and therefor plan an upgrade to 2017.2.

Now my question to you bold ObjectScript warriors:

• Did anyone do this with a legacy application (still have macro routines, the old style)?
• Has anyone experienced any bigger issues with a move like this?
• Are there existing checklists apart

I need to record all incoming email into data classes. 

After asking around , no-one has come up with an answer, I have confirmed that is is being done.

The application is in the cloud and the customer exchange server is in house.

Is their a way to (setup) automate the removal of users accounts from the system once they have logged out of cache and than recreate them once they log in, so basically the user list only contains live logged in users plus some of the default user accounts.

Hi, 

Can we create a new class in the studio using any command rather then using the Menu Item Option from Menu Bar in Studio . 

Requirement : Create/Draft a new class and able to extends the other classes using  a command in Cache Class .

In other words , I want to Dig in the Menu Item class from which Menu bar is created in studio and option are provided  Like New..., Open..., etc 

Thanks,

Hi!

We would like to retry message so that it's restored to end of operation's queue. This is in situation where order of messages is not needed to be handled by Ensemble, there is version number in message data and receiving application can ignore incoming message if necessary.

We would try to send message until it's accepted (or manually suspended), but this should not block operation's queue.

We have already this in actions:

D - Disable the Operation, log an error and restore the message to the front of the Operation's queue.

Would be nice to have one like this:

Q - Disable the Operation, log an

Hi all,By using LDAP cache method ##Class(%SYS.LDAP).GetValuesLen(LD,CurrentEntry,Attribute) we get the list of attributes but in "ObjectSid" attribute have the SID in binary format(objectSid^U¤:c@ãºþÕLCP]). how to convert to the readable format from the binary format in cache side.

Hi Community!

I want to share with you my impressions of Global Summit 2018.

It was my first time in the USA and my first Global Summit. And I can say that it was really amazing trip and a great experience!

I have been building Business Processes in Ensemble for a few months and in a process i'd use a combination of data from the request that started the process and context variables that where filled by earlier calls in the process as input for a data transformation. I do not know how to achieve that.

What I do currently is that in my process I first call a data transformation and then make a call to an operation.

Hi, Community!

I'm pleased to announce that InterSystems Open Exchange is now operating and available for everyone!

Hi, Community!

Just came back from Global Summit 2018 and want to share my impressions.

Key highlights of my choice:

1. The announcement of a new InterSystem Data Platform: InterSystems IRIS for Health!

2. Community and Express licensing for InterSystems IRIS 

3. The Launch of InterSystems Open Exchange - the gallery of InterSystems Solutions, Tools, Technology examples, Adapters, and Interfaces! E.g. test coverage tool and Ethereum Blockchain Adapter

Hello!

Is it possible to use Cache Studio on a Linux operating system? Maybe there are similar tools for Linux?

Hi all,

I'm pleased to announce this personal project to convert a number to text, in spanish, english, catalan and russian.

the aim of this function is to convert numbers into text. It allows a maximum number of 15 digits.

I have created some roles, and would like to know if there is a way to export the Roles and save them off to a file? I want to create a backup file of these roles for DR purpose, and in case I ever get hit by the preverbal bus.

Thanks

Hello,

I am a beginner with Object Script and I hope anyone can help me solving my questions.

1. Is there a way to time a loop in Object Script? 

2. My code leads to the following error, even though it executes the method.

Is there a way to ignore this specific error, so that I can repeat my code in a time loop over and over again without stopping?

• Load a ML model into InterSystems IRIS
• K-Means clustering of the Iris Dataset

Hi 

Anyone worked on "ccontrol  list " command execution through Cache Object Scripting.

I executed through  bat file passing this ../bin ccontrol  list  . Icould not get the results through COS  but executed in command prompt

Need help here to address the same stuff through cache object scripting.

Hi,

This is available on github and wairing for approval on the Open Exchange.

It  allows you to

• "Serialize" any class instance that extends from the adapter to a DynamicObject.
• "Deserialize" a DynamicObject to a class instance that extends the adapter.
• References to other classes can be followed recursively and serialized.
• Arrays and lists of Serial objects and DataTypes are handled for serialization en deserialization
• Arrays and lists of Persistent objects can be serialized in full, on the deserialization it can't create referenced objects, but an array or list of ID values can be provided and it

Hi folks,

I've created a datatype class whoch extends from %Library.String with a REGEX parameter and the validation of the value against the regular expression. The class does not support Populate using the regular expression as a template for data population.
