Hi All, I am a Data Architect and am trying a method of deploying alter statements onto Cache DB.

My Data Modeling tool generates alters as this.. So question is if the Cache has a way to rename table? If so what is it?

ALTER TABLE <SchemaName>.GROUP_TYPE_NODES RENAME TO GROUP_TYPE_10082019140110000
;

This is giving error.

Common Testing Frameworks.

Hi,

I'm after feedback and comments on the sort of tools and approaches the wider InterSystems community uses for QA Testing applications written in Cache/Ensemble or IRIS. I am aware of the %UnitTest package, and understand how that works... but:

- Do you use an alternative or framework built around this native Unit Testing tool ?

- What is your experience with %UnitTest if you use it ?

- Is there a tool you would recommend for your UI (I know this is not specifically an InterSystems' related question)

We have a SOAP web service that we call to retrieve a stream of a PDF file. The web service is written by another group in our company (not a Cache group). We are running into one issue where it seems that the PDF is too big and when it is sent to us we get this "ERROR #6301: SAX XML Parser Error: <STORE>". The stream is about 8mb. This is the first time that we have encountered this issue.

We have a WRC ticket open about this but doing some research, we found that if we increase the $ZSTORAGE then we no longer get this error when we call the web service for this 8mb file.

Hi,

Kindly find the below example :

If I open google chrome and I add the below link (just an example) , it will download a file to my local PC.

https://www.abc.com/cgi-bin/ocs/pswd=123&rpt=1

pswd correspond to the password

rpt represent the report

How can I do the above using code in cache studio ?

What type of services should I use? what's the parameters ? functions? and how can I test it?

When I start a fresh installed IRIS or a Container I always find Interoperabiliy (aka. Ensemble) mapped to namespace USER.

Is there any utility to remove this mapping by a click ?
unmapping it global by global, routine by routine, Package by Package is just a boring exercise.

To be clear: I look for a utility inside IRIS.

The external utility is obvious: Notepad (or any other text editor)
- clean iris,cpf,
- restart IRIS
It's fast, it's efficient, but it's really hardcore.

DTL vs. ObjectScript

As I've become a little more familiar with HealthShare, I'd like to start exploring different ways of doing things. To date, the bulk of my data transformations have been using DTL; only using ObjectScript for a few operations that write to external SQL tables that were largely based on examples provided by my sales engineer.

Until this week, my customer had Ensemble writing HL7 messages to my TCP listener, working fine on ageing physical servers (Windows Server 2003, Caché 2009). They had four app servers (app1, app2, app3 and app4) with an overarching DNS simply called "app". Ensemble was connecting to "app:port", and it somehow found whichever of the four app servers my background listener was running on, and the interface worked fine for 10+ years.

Customer is experimenting with %vid variable for selecting row numbering for sql queries. Basically he's trying to implement paging functionality.

He is confused that select %vid from (select ...) returns dummy number whilst select *,%vid from (select...) returns correct data.

I am trying to connect to an external SFTP. They have our public key and I have the private key which is password protected. I have the credentials set to the sftp username and the password to the private key.

If I set the private key only, I get a username/password error connecting. If I set both the public and private key files, I get the error below:

ERROR #7510: SSH Error '-19': SSH Error [80101013]: Callback returned error [80101013] at Session.cpp:418,0

I am going to start playing with Zen Mojo (again) and as I understand it there are two ways to manage moving data to/from your Zen Mojo page:

  • interacting with REST services
  • using Mojo's built-in transport

I would like to understand the pros and cons of each approach. Which is recommended in different situations and why? I would like to create a sample application that will hopefully be reusable and helpful to others and I would like to understand which approach to pick for my app.

Global ^Errors growing fast

Hello guys.

Can anyone help me about Global ^Errors? Only in 1 specific namespace is it growing fastly. It grows from 2 to 3 Gb per hour when all services are active. Which commands exactly do this? In another similar namespaces, there is not that Global in the class list.

Thanks.

I have a persistent class where I am logging each CCDA I receive. I want to store all of the providers associated to that CCDA (many to one). In a relational database, I would have a child table with a foreign key to the primary table. I'm guessing the equivalent to Cache would be

1. Create a custom class (ProviderList) with the properties I want to store.

2. Add the class as a property of my CCDA persistent class.

Property Providers as Array of ProviderList (SQLProjection = "table/column";

Am I on the right track?

Back in my COBOL days, there was a utility that would analyze running COBOL code and expose bottle necks and those modules that were inefficient or were executed multiple times. This was to help the programmer know where to concentrate streamlining efforts.

Is there any such utility for Caché Routines?

Hi,

We want to monitor an Ensemble Production and send custom email alerts in function of some Rules. For example, if we normally receive 1 message per second, if suddenly we receive 5 or more messages per second, we want to send an email alert. And if tomorrow we don't want to check this again, we want to disable it through Ensemble Business Rules.
