#Caché

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

Documentation.

I am in the process of creating a python report writer that includes the information contained in "License Usage" page of the management portal. I think I have a handle on the local values contained in the report using the %SYSTEM.License class I have those defined using these methods:

Current License Units Used - -> LUConsumed

Maximum License Units Used --> LUMaxConsumed

License Units Enforced --> KeyEnforcedUnits

License Units Authorized --> KeyLicenseUnits

Hi,

I am running InterSystems iris 2021.1 from the container and I have version 2020.1.1 is installed locally. While running studio locally I am getting below error message:

"Version mismatch. Studio version 2020.1.1 unable to connect to server version 2021.1
Upgrade to a later version of the client to resolve this error"

Looking Forward

Thanks

I'm new to cache, come from an oracle and sql server background. In oracle and sql server I could write basically a stored procedure like script and pass it in as text to the command to execute.

Example:

Below would be the _sqltext

DECLARE @Id INT;

select id into @Id from something;

if @Id = 9

BEGIN

do something

END

The _sqltext would work in sql server, what would be the equivalent for cache for it work?

I get a generic error when I try it with cache

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?

I am writing a Python tool to query our cache instances for various information. I have set up the connection without issue:

import intersys.pythonbind3 as pyb

conn = pyb.connection()
conn.connect_now(.....)

db = pyb.database(conn)
qry = pyb.query(db)
obj = pyb.object(db)

I wanted to make the call:

execRes = qry.prepare_class("SYS.Database",'FreeSpace')

But fetching fails because of data mismatches ( as I understand from other posts) and my testing bears out this type of failure.

How to become a time lord - Time travel

Time travel is like visiting Paris. You can't just read the guide, you have to throw yourself into it. Eat the food, use the wrong verbs, get double the charges, and end up kissing complete strangers.

The Doctor

We are now going to travel through time, that is, we are going to see future and past dates and how to calculate them in different formats. The TARDIS doesn't wait, take the controls and hold on tight.

ECP system ID

Hi,

I'm looking through some journal entries in the hope of finding the root source of an issue.
I was wondering if and how you can map a "ECP system id" to a server.

Any hints would be welcome

Best regards
Ivo

Two new sets of maintenance releases are now available:

  • InterSystems IRIS 2020.1.2, IRIS for Health 2020.1.2, and HealthShare Health Connect 2020.1.2

Installation kits and containers can be downloaded from the WRC Software Distribution site. Container images for the Enterprise Editions of InterSystems IRIS and IRIS for Health and all corresponding components are available from the InterSystems Container Registry.

Hi,

I was playing around with the python binding for caché (2018.1.4) and I ran into some problems.

When executing the class query "List" from SYS.Database the pythonbind interface throws an exception, that seems to be caused by a mismatch of the defined SQL datatypes for this query and what is actually returned (or the lack of type conversion in the pythonbind interface).

Is this a known issue ? Are there solutions/workarounds for this,
Or is this a bug ?

The details:

Is there a way, for testing purposes at least, to change a CSP session over to a different user? We have a lot of things in our system that are allowed or restricted based on the user login, so it would be useful for me to be able to occasionally run as a different user to see how things look and work for them. I've tried using the %CSP.Session.Login function, but that still shows the CSP session as being from the original user, not the one I've switched to.

Maximum Global Size ?

Dear people,

I (really) spent hours on finding the maximum size a Global is allowed to be (for Windows, if that matters). All I seem to run into are database sizes (derived from a max number of blocks and block size), but I refuse to believe that is correct because too small to be realistic. surprise

Java Connection Strategy

We are planning to build a REST API with the Java Quarkus Framework.

  • There'll be a connection pool;
  • The DataSource instance will be automatically injected from the connection pool;
  • We will use JDBI to do SQL instructions and this will give us automatic Connection and Statement management;

This Caché instance already have COS applications running and consuming connections and licenses.

After doing this, we will migrate to IRIS.

Designing valid hierarchies in DeepSee

When designing a hierarchy in DeepSee, a child member must have only one parent member. In the case where a child corresponds to two parents, the results can become unreliable. In the case where two similar members exist, their keys must be changed so that they are unique. We will take a look at two examples to see when this happens and how to prevent it.

I have a SQL query that I want to run against MS SQL from cache ensemble using the SQL outbound adapter. If I run this query direct from MS SQL Studio it take about 7 seconds MAX and returns about half a million rows. The row only contains one column it is a number all same size and if I run this query in the production in ensemble it takes for ever the production finishes without getting the response back. The same query run in cache outside the ensemble environment writing results to a file it returns results taking about 3minutes to complete.

Does anyone have experience using SCCM or any other enterprise application management tool to deploy updates to a thick client (internally developed standalone app) across the enterprise? I have a client that is attempting to get this working for their customer and running into some trouble. If you have any knowledge or experience you can share it would be greatly appreciated.

I have read some MS Technet pages that appear to indicate this is possible

We have a situation where we want to save the patient photo (or any other attachment) received via FHIR to a persistent property without decoding it. When it is sent out again using FHIR is is stored in the encoded format and need not be encoded. We do not need to decode it for our application. We always use it on another system that retrieves it or saves it via FHIR and therefore it is always received or sent embedded in JSON.
