InterSystems Caché is a multi-model DBMS and application server. See more details here.

Documentation.

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.

Hello InterSystems Community,

We're excited to announce that we've completed our first Open Exchange submission for InterSystems platforms.

BridgeWorks VDM is an ad hoc reporting and graphical SQL query builder application that was designed for any user who needs access to their SQL projections in InterSystems Caché, InterSystems IRIS, InterSystems IRIS for Health databases as well as access to InterSystems DeepSee and InterSystems IRIS BI Cubes with minimal SQL scripting experience.

VDM features:

Hi everyone. I'm new to cache, and i was looking for a command who reads a .txt file and store the informations in variables. I've found on the documentation the EnsLib.SQL.SNapshot class, and, even if i'm not sure if that's what i need, when i run the code it says that the class doesn't exist, but i couldn't find the right superclass to extend.

Transactions in Global InterSystems IRIS

InterSystems IRIS supports a unique data structure, called globals, for information storage. Essentially, globals are persistent arrays with multi-level indices, having several extra capabilities—transactions, quick traversal of tree structures, and a programming language known as ObjectScript.

I'd note that for the remainder of the article, or at least the code samples, we'll assume you have familiarised yourself with the basics of globals:

Hello Everyone,

I'm want to know, what is more common for your company to use, the abbreviation syntax or the complety name of commands, and why?

Ex.

S VAR=10 / D FUNC^ROUTINE F 1:1:1000

Set VAR=10 / Do Func^Routine / For 1:1:1000

set var=10 / do func^routine / for 1:1:1000

Here in my company, we are familiar with the abbreviation syntax, because to spell is more faster.

Hi developers!

I just want to share with you the knowledge aka experience which could save you a few hours someday.

If you are building REST API with IRIS which contains more than 1 level of "/", e.g. '/patients/all' don't forget to add parameter 'recurse=1' into your deployment script in %Installer, otherwise all the second and higher entries won't work. And all the entries of level=1 will work.

/patients

- will work, but

/patients/all

- won't.

Here is an example of CSPApplicatoin section which fix the issue and which you may want to use in your %Installer class:

    <CSPApplication Url="${CSPAPP}"
      Recurse="1"
      Directory="${CSPAPPDIR}"
      Grant="${RESOURCE},%SQL"
      AuthenticationMethods="96"
      />

Why log in to view pivot tables when you can have them delivered directly to your inbox? Are you in need of automated reporting for InterSystems IRIS Business Intelligence? Pivot Subscriptions is your solution: a tool for subscribing to scheduled email reports of pivot tables inside InterSystems IRIS Business Intelligence (previously known as DeepSee).

I am trying to make architecture for my project. And for it, it needs to make list property in which there is list of objects of another table, the data must be unique, therefore I make sql-query to check objects of another table if it is used or not, but I can't make sql-query to check elements in list in property with elements of another table. Can you help me? In property ID of object is used.

Pretty straight forward.

I'm tempted to hard-code ISO-8859-1 inside my VSCode extension when working with CSP because this seems to be the encoding used by default, but I need to know if there's any other possible configuration. So can you share your experience when working with CSPs? Like issues with encoding, discoveries regarding it, workarounds etc.

Also, can someone tell me if it's possible to work with UTF-8 encoded CSP files using Atelier without breaking the encoding of the output file?

Hi,

It turns out that on windows if you run a command with a windows command file you need to escape the % character as %%

In my case I could test freeze and thaw calls at the command line successfully as

..\bin\cache -s. -U%SYS ##Class(Backup.General).ExternalFreeze()

...but when my freeze script ran it would fail.

it turns out that a single '%' is striped when run in a windows command file, and it must be escaped as '%%' windows gets:

Hi,

I believe the healthshare Debug module did this (if you added it) but I no longer have access to Healthshare to look so am asking here.

Suppose I have;

Set fruit="apple"

set person="john"

d ..Something(fruit, person)

quit

ClassMethod Something(objs...) {

; Names of variables passed in

}

In side "Something" how can I see the original name of the variable passed in (i.e. know the variables passed in were called fruit and person and not just their values).

A few years ago, I was teaching the basics of our %UnitTest framework during Caché Foundations class (now called Developing Using InterSystems Objects and SQL). A student asked if it was possible to collect performance statistics while running unit tests. A few weeks later, I added some additional code to the %UnitTest examples to answer this question. I’m finally sharing it on the Community.

Hello community!

I have a question about the %OnSave method of a class. We have a class that has two properties that are classes.

Class A

Class B

Class C

Class A.PropertyB as Class B

ClassA.PropertyC as Class C

Classes B and C also need to point back to Class A - it's just the way it is. We need to be able to use any one of these classes and get to the others (it's actually even more complicated than this, as Classes B and C also have a PropertyC and PropertyB as well, respectively) :

We are currently implementing the Data Innovations Instrument Manager product. In setting up our backup process we are wanting to use Veam snapshots. The application runs in a Caché 2016.1/Windows Server 2016 instance. We are running an HA primary/secondary/arbiter config. The statement below is from DI. I am curious to see what others that have implemented the DI Instrument Manager in the same or similar config have in place for backup.

"DI recommends is recommending that we not perform snapshots, but if you do choose to do so, here is some important information to consider.

InterSystems has corrected several critical defects that can result in data integrity issues. These defects were identified and corrected within a short time, so InterSystems has simplified the upgrade process by consolidating them into a single package. The effects of encountering these defects may not always be visible.

I have a custom written date, setup as myDate in my application, which always behaved fine for years, and now it's acting a little weird.

When I run SQL in Display mode the date shows as 1/10/1841 for some but not ALL rows.

When I run the same exact query in logical Mode the date shows normal format, in my case, for example 10/1/2019. When the application is running is shows the incorrect date. When I run the terminal session and open a ref point and ask to write a date is shows 10/1/2019, but I am expecting internal format here - 65287.

Question
· Nov 1, 2019
Compaction of Large globals

I would like to Compact globals in a database to free up space.

I would begin the process on Saturday morning, but am concerned, due to the size, that it would not complete by Sunday evening. I understand that the process is setup so that it can run with users on the system, however, as the advice indicates, this would not be ideal.

Can the process be stopped if it does not complete by the time you want/need it to?

Do you know how to guestimate how long the process would take?
