Timeout for $zf

In one of the projects, when we have ECP with 10 ECP application servers, from time to time we faced the issue when our journals fail to purge, due to open transactions. While we have about 100-150 GB journal files per day, it quite quickly became a big issue, and with mirroring a very big issue. Mostly we just rebooted our ECP Data server, so it searches rollbacks any transactions, but such process is too long, may steal a few hours. I did not find any way, how to get the list of the open transactions from one place from ECP Data Server. We just migrated our Data server to 2018.1.

This is my first post, I have only been using Healthshare for a year.

We support multiple Healthshare test and development environments. We are trying to come up with the best solution for building an environment from scratch, as well as incremental updates. I am interested in hearing the pros and cons between using the Ensemble -> Export Production feature versus creating custom classes to do the install and setup.

I'm finding that in a mobile app setting, that Cache is causing the worst User Experience that I have ever seen in a mobile app - I'm just saying this hoping that someone will be able to help me out, my intent is not to criticise Intersystems.

We have a Xamarin Forms mobile app that consumes web pages that are created by Cache. The app compiles into iPhone, iPad, Android Phone, Android Tablet, UWP (Windows 10, all of phone, tablet, and desktop), as well as MacOS.

How suitable is Docker for standalone deployment of an Ensemble version and Ensemble application together?

The context is deployment by an application partner of an integration application and the supporting Ensemble version as a single package (single file ideally), to multiple environments and to multiple customer sites.

I don't have experience with Ensemble on Docker so I'm wondering what gaps and pitfalls may exist.

Data transformations can be changed in Management portal, but the modifications are not synced with visual studio code. Classes are synced from VSCode to Iris. VSCode can take care of the git repository.

I am curious to know how people are developing data transformations on Iris with VSCode? Are you editing the DT classes with VSCode and forget about the UI? Are you exporting from management portal the files to VSCode directory? Are you using a source control hook?

Thank you

Hi all!

I'm developing a mini-framework to implement annotations in Cache. I want to support two kind of annotations: metadata and method decorators. I've got stuck trying to implement the second one.

Metadata

With metadata annotations I can add metadata to any kind of target. A target can be a method/classmethod, parameter, property and class.

For example:

If I were trying to access an index of a global variable, what time complexity would this operation have? My understanding of languages like Java/C++ is that arrays are stored as blocks of memory so that x[15] would have a lookup time complexity of O(1) because it just goes to (address of the array + 15) and retrieves the value stored there.

How does this work in Cache where the index of a variable isn't necessarily an integer value? If I were to have a variable like the following:

x("Adam") = "Red"

x("George") = "Blue"

x("Bryan") = "Green"

etc...

For my recent tutorial, I used %Query Wizard of Studio.

Could any of the VSCode experts please show me how to generate

Query Statement with input parameters, CONTAINID , ROWSPEC
and the required class methods

I was just not able to do it.

Atelier and overriding

I'm used to using Class/Refactor/Override in Studio to override methods, properties, xData blocks, etc regularly.

I can't see how to replicate that in Atelier at the m moment. Is this possible ?

Just curious how many companies use in their work Docker containers, I mean not only with InterSystems products. And if such companies exist, which of them uses docker and doesn't use it for InterSystems products by some reasons. What are the reasons? For companies which already uses InterSystems in containers, how do you use it? Development environment, testing or even in production ?

And if you don't use but thought about it, what are the reasons which stop you.

As for me, I've been using InterSystems Caché inside a Docker container in some different cases:

httpRequest POST file Upload multipart

1. is there a code example step-by-step, how to build each part ?

I tried the demo from intersystems doc's,

I checked it in .Net response, that didnot recognize the File-data part

2. I noticed, there is :

SET BinaryMIMEPart.ContentType="application/octet-stream"

but missing :

SET BinaryMIMEPart.ContentDisposition (as analogue, let say for VBA EXCEL )

or I do it via the:

Do BinaryMIMEPart.SetHeader("Content-Disposition",...) ?

that is not analouge for VBA

I have created a global say ^myglobal and entered some data. I am storing the name of global in databases and fetching the name based on some criteria. I am getting "^myglobal" in return from databases but i am not able to fetch the data I stored in the global.

I tried set var = result.global which gives me "^myglobal" in var. Doing WRITE var will return "^myglobal" and not the data i stored in this global.
