We've been tasked with developing a file upload module as part of our wider system, storing scanned documents against a patients profile. Our Intersystems manager suggested storing those files in the DB as streams would be the best approach and it sounded like a solid idea, it can be encrypted, complex indexes, optimized for large files and so on. However the stake holder questioned why would we want to do that over storing them in windows folders and that putting it in the DB was nuts.

IRIS or Cache?

Hello all, 

I am in a bit of a situation where I could get your help please. 

I want to get certified with IRIS, but I also do see that there is an availability named Cache. 

Are they both the same or different? if different please explain it to me as how? 

Also what is the difference between IRIS, IRIS for Health, Deep Sea? Please explain to me.

Also what do you think I should get my self certified with? 

Please leave your comments below.

Luhn Mod N in Cache?

Hi all

I'm trying to recreate this method below in Cache/IRIS. 

https://en.wikipedia.org/wiki/Luhn_mod_N_algorithm ISO-7812-1 (LUHN-10)

I've been following the javascript example. It seems simple in theory but i'm struggling with which cache methods to pick.

$LENGTH, $System.SQL.FLOOR() - seem ok

$EXTRACT - I think for .charAt (though may need to correct base)

$FIND - for .indexOf

Any suggestion which would be the best ones for the job?

SSLConfig with ECC

Hello everyone,
I can choose between RSA and DSA. ECC seems to be unsupported.
Is there any workarounds without using external binary like curl?

Best regards

Hello,

I created a custom business operation to copy PDF files in Intersystems Healthshare. To copy the files I used:

$ZF(-100, "", "cp", "-f", tSource, tTarget)

tSource contains the source file e.g. "/opt/var/data/dir/1821008687135422926_5849146876.pdf".

tTargetSource contains the target file "/opt/targetdir/Müller_Jörg_1821008687.pdf".

Copying files without german Umlaute works fine (e.g Smith_Robert_1821081542.pdf), but when the string contains special characters like "ä", "ö", "ü" or even  "ß" copying is not successful.

At the heart of IRIS and Cache is a very interesting database architecture that we, at M/Gateway Developments, refer to as "Global Storage".  If you ever wanted to know more about the fundamentals and capabilities of this underlying database, you might want to read a major analysis we've put together:

Amongst other things you'll discover that:

$preprocess failure

There is an undocumented command, $preprocess, that can be called as below. In this case it takes the class name and converts its code into a text array. That includes comments as well. Two questions about it if you know:

Hello Community,

we read data from an Oracle database. The desired order is created by an 'order by' in the sql statement. The individual elements of the result set are converted into objects and inserted into a parent object using 'insert' on a property, which implements a one-to-many relationship with the result objects. Later, we iterate over the objects in a for loop and process the contents. At this point the order is apparently no longer identical to the order in which the elements were inserted.

Hi Team, 

      A month ago, we purchased the cache license for a 10user limitation. We are a 6developers and using 3different development (internal)servers for this same license. All Developers aren't login at the same time. We have a limitation for login 2developers at a time in a server. But sometimes, we are facing a <LICENSE LIMIT EXCEEDED> issue.   We don't know why we are facing this one.  So anyone please guide me, why we are getting this type of issue. I have attached the errored screenshot.

Hi Team,

I have a requirement to delete the Ensemble interfaces , as per User request. I would like to write a routine for that and once I execute, it should remove the interface components through code.
Could you please provide code samples for the following actions ?

  • Deleting an individual rule from a rule class
  • Deleting a class from Ensemble
  • Deleting a Host (Service/Operation/Process) from the Production.

Appreciate the help.

Thanks,

Hello everyone,

 

I have a doubt, its possible to use interface like C# using COS? 

Remember, interface is different from Abstract Class, because a abstract class can implement code in the method, so I don't want this, I want only define the methods from Class, not allowing implement code.

I'm looking for a SQL function equivalent for SQL server STRING_SPLIT.   I have records like this:

join_to_tx_history (key), ss_note_multi_dict_1_value (varchar)

64559.001 Assistant Principal, Case Worker, Client, Dad, Daughter, Mentor, Mom, Other, Principal, Psychiatrist, School Counselor, Teacher

and I like the field ss_note_multi_dict_1_value split to rows for each comma delimited value.  So I can get this:

Hello Community,

We want to send ALL updates from our Cache server to a remote SQL Server instance that will be used as a reporting data warehouse.

Has anyone done this already and if so what is the best way to go about setting this up?

Thanks

Hi,

I'm getting thousands of errors like the ones below:

 

2021-05-03 14:11:44 [SQLCODE: <-400>:<Ocorreu um erro fatal>] [Cache Error: <<READ>Dispatch+14^%SYS.BINDSRV>] [Location: <ServerLoop>] [Client info: <Username: KIORAS, Node Name: 3IK0VLS5UU, IP Address: 192.168.1.223, Executable Name: EXTRService.exe, Internal Function: B0>] [%protocol: <52>] $Id: //ce/2018.1.2/kernel/common/src/aclass.c#1 $ 23468 104

objects in javascript :

var oM = new Object;

var mMode=["down","up","click"] ;
var key,val ;
    for (key in mMode)
    {

       val = mMode[key] ;
        oM[val]={} ;
        oM[val].id   ="" ;
        oM[val].type ="" ;

       ...

 }

so I can access the .type directly as :

oM.down.type

or:

oM["down"].type

what is the syntax in CACHE or IRIS, to achieve such approach via class/key/property...?

acctually: class/object/key/property anlaogue to ^GLOBAL(key,"property")=val

Let's say I have a persistent class Sales.
I need to create a report that shows the amount of sales for each branch.
By simply using the class Sales for the source of the cube, I can show what I want with one little exception - the branches that did not have any sales are not shown.
Is there a way around that that does not involve creating a whole new table just for this cube or using a Data connector (they have horrible documentation and I am unable to figure out how to use them properly)?

I need to show the absence of data, so I have to join the list of predefined values with a result of a select statement.
However, it seems like Table Value Constructors in JOIN are either not supported, or I do not understand the syntax.
Basically, I am going for something like this:

Select v.valueId, m.name 
 From (values (1), (2), (3), (4), (5)) v(valueId)
     left Join otherTable m
        on m.id = v.valueId

Is it supported in Cache SQL or not?
