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

Documentation.

Is there a way to add specific table permissions to a security role programmatically? I'm working on scripting some of the initial setup work when we sell certain add-ons to our software, and I see how I can assign resources to a role and give it a description, but I don't see how I tell it that this role gives the user, for example, SELECT privileges only on the invoices table, or SELECT, INSERT, UPDATE, and DELETE.

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.

This error occurs when an instance of the class is already open at compile time.

There are two ways to deal with this issue:

  1. Terminate the process or application that has the instance open
  2. Compile options in the studio build menu: Check the compile flag “Compile classes in use” and compile.

If you want to determine which process is using the class, try the sample routine below.

NewBie's Corner Session 20 Parameters and Status Part I

Welcome to NewBie's Corner, a weekly or biweekly post covering basic Caché Material.

Parameters

Parameters are another name for Variables when used in passing data from one Routine to another.

Let us say we have 2 routines (RtnA and RtnB), and we want to pass 3 parameters (Parm1, Parm2, Parm3) from RtnA to RtnB.

RtnA would look like:

.NET Gateway vs. Java Gateway

Hello,

we have to implement some application logic using either Java or .NET. Which should we choose? Given that all other considerations are equal, which is in your experience better way performance-wise to interact with external components in Caché: .NET Gateway or Java Gateway?

Thanks.

Sometimes you can face the situation when you did update the web app on Caché server but you cannot get the newest version of the app in a browser.

Here are couple recipes which help me to solve it. From simplest to more sophisticated and not obvious.

1. Refresh page in a browser

In Chrome it is Ctrl+R or 'Refresh' button. Obvious, but helpful.

2. Hard reset in a browser

If you are in Chrome, open Developer tools

There is a finite list of date formats that users want to use to enter a date in a form. These formats include single digits for month and day and double digits for year. The field is represented by a dateText control.

How would one get to allow a dateText control to accept multiple date formats ? I see only 3 listed here, do those include using single digits for month and day ?

Custom %ListOfDataTypes

Hi community.

I want to create a custom list inheriting %ListOfDatatypes in order to implement some methods like Map, Filter, ForEach, but I have some questions.
Just to mention, I have already read the topic about DeclarativeCOS.

When I define a property like following, caché uses %Collection.ListOfDT or %Collection.ListOfObj, as it's shown in the documentation

Working with a client who has two TryCache instances on his W10 machine. Trying to bring in globals from a text file which works fine in my environment but on his, he cannot make ^%GI accept a file from his C drive. His Cache is on C as is mine. Checking the path and the file name carefully, it is accurate. D ^%GI and enter the path with filename (as works fine for me on my system) and he gets a message [unavailable] and when he hits enter out of that message, he sees Cannot import from THIS device. I think I'm missing a config or security setting of some kind but I don't know what it is.

SQL gateway. 'Locking' problem.

while debugging, is there in Caché a command to 'unlock' the instance of a class ?

close class, and kill class is not enough.

same problem in %Activate link

for each debug I have to exit (Halt) the terminal,

make debug in C#

coming back , and re-load again in Caché.

Regards,

Emanuel

I'm connecting to a remote device using TCP. It has a binary protocol.

set host = ""
set port = ""
set io = $io
set device = "|TCP|7000"

set timeout = 2
open device:(host:port:"M")
use device:(/IOT="RAW")
read string:timeout

use io
zzdump string

The problem is when reading from it, I get a 0A (also known as 10 or \n or linefeed) byte, which terminates the read.

Expected output:

0000: 42 00 7B 0A 11

But I get this output:

0000: 42 00 7B

How can I fix that?

Hello, community!

I've stumbled on some unexpected behavior, and decided to check with you if this is normal. Basically, I'm rebuilding indices and the result is not journaling (which leads to missing indices at shadow server).

The $ZV is "Cache for UNIX (Red Hat Enterprise Linux for x86-64) 2015.2.1 (Build 705U) Mon Aug 31 2015 16:53:38 EDT"

I have an example class 

Class tmp.A As %Persistent;

Index IP1 On P1;

Property P1 As %String;

for example there is one object which have P1 = 1, so

Hi everyone,

I have an existing application on HealthShare 2015 and decide to move it to HealthShare 2018 to make use of Atelier support. I am using Eclipse Photon with Atelier Plugin 1.3.

Most of things are working better on Atelier comparing with Built-in studio of HealthShare. However, when I tried debugging CSP file with Atelier I encounter 2 problems:

Hello there,

Someone know which impact would have my database changing the locale and its collationTable? I understand it should works fine, without any drawback.

Could someone else confirm my assumption or tell me what could happen? Has anyone changed something like that? (Not to russian, japanese, chinese, etc..)

About queries.. is there any side effect?

Regards

I'm trying to save a list of AccessTokens a user for a specific user. This way I could present it together with other user-data.

I have tried calling ##class(OAuth2.Server.AccessToken).OpenByCode(authCode) from %OAuth2.Server.Authenticate's AfterAuthenticate() method. This only returns things like State and AuthorizationCode, but the AccessToken is empty at this point (afterwards it becomes filled out).

Is there a way to achieve storing the AccessToken as part of the login system?

I have a python script that is pulling the cache instance key expiration date ( KeyExpirationDate() ) which comes back as an integer. With the queryscript function - $ZDATE(73284) I can derive the actual expiration date. Is there a manner or method of creating an equivalent Python script that will convert the integer return by the KeyExpirationDate() method into a date string?
