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

Documentation.

I’m trying to connect to an InterSystems Caché database from my local development environment using an IPv4 address. Most examples I’ve found show how to connect using the ODBC driver with the localhost or the default IP address (127.0.0.1). However, I want to know how to connect using my local IPv4 address.

Here’s what I need help with:

I have a repeatable field within HL7 that I want to create a List from. Do I have to initialize the List by using $LB, or can I just use $LI to keep adding on to the end of the list as it is looping through the field?

REST API Issue

I have a rest API Class used for getting data from Cache 2018 version.
I have single route '/callfuntions'
I send the following parameters to the API :- className, methodName, params
I use $CLASSMETHOD to execute and send the result back to the client.

If I make more that 10 to 12 requests in quick succession, then it stops sending data.

Hello everyone

I have a question about the maximum number of active license users for CACHÉ.

When I run the command: Do $System.License.ShowCounts()

0 CSP users currently active
1 Maximum active CSP users
0 CSP sessions currently in 'grace period'
1 Maximum CSP sessions in 'grace period'

I have a few routines in ^rINDEX that are missing in ^ROUTINE. At least some of those routines lack a timestamp, probably Date and Time Modified in ^rINDEX. It causes D %RO crash when such a routine is referenced by a routine range, since "" is an illegal $ZDTH value.

Healthy entry (note the timestamp): ^rINDEX("ABC,"INT") = $lb("2021-06-15 15:08:38.846885",) ;The second argument is sometimes present and sometimes not, likely the routine size.

Unhealthy entry (note an empty timestamp): ^rINDEX("DEF,"INT") = $lb("",21)

I inherited some legacy MUMPS / ObjectScript code. A code review identified an exclusive NEW and that is not allowed per our coding standards.

The original code contains:

RUN(CALL,DRVNAME)
S $EC=""
S ^TMP($J,"RMPV","DRVNAME")=DRVNAME
N TMPFILE,OLDIO
S OLDIO=$IO
I $G(^TMP("RMPV","SILENT"),1) S IOP="NULL",%ZIS=0 D ^%ZIS I '$G(POP,1) U IO
D INIT^@DRVNAME
D ; scope variables
.N (DUZ,CALL) ; Protect %response
.S IOF="""""",IOM=80,U="^"
.D @CALL

Hello, I am total newbie when it comes to ObjectScript (just started going through the tutorial). We have a task where we have to update the port number for 75-100 items (say for half of the items in our production). Going through the documentation and other community posts it looks like we could utilize class method 'ApplySettings' in Ens.Production. But we are running into an issue. Below is what we currently have. When we hard code the item, it works. But, if we store the item in a variable and try it pass it through. Then it doesn't work. We are also not seeing an error.

We have a CSP pages script, which gets and sets a cookie for email tracking purposes, we had problems with cookies not being passed to this script when the URL was opened from an email client due to being cross-site, so I set Session Cookie Scope & User Cookie Scope to None instead of Strict.

This solved the issue with cookies not being passed, however the script entirely does not work anymore due to the error:

"Invalid CSP response cookie. SameSite cannot be set to None without Secure. : CSP Error"

Hello everyone,

I just want to know if there is a difference in performance between using Class methods versus MAC routines?

For example:

do Method^MyFunction()

versus

do ##class(MyFunction).Method()

I'm running a query, joining nine tables together. When I run it with a SELECT COUNT(*) I get about 200,000 rows. When I run the SELECT with the columns I want, I get about 2,700 rows. Is there something inherent with the queries that limits the result set size, or anything I can do to make sure I'm getting back all the results? Rather, than trying to run it about 100 times limiting all previously gotten accounts.

Hi

Is there a way to generate an MD5 checksum of a file by performing a checksum against the file's parts? We potentially have to process large files and therefore cannot keep the entire file in memory. From what I understand checksum related logic is typically stateful, allowing file data to be passed through sequentially, however it appears cache script offers only stateless functions offering a simple method of generating a single checksum hash from a single string (or stream), correct me if I'm wrong?

I have an old .NET 4.5 project, working with database InterSystems.Cache. The project is deployed on a Windows server. Data is retrieved using the InterSystems.Data.CacheClient.dll library.

But now I'm planning migration of the project to .NET 8 to container with linux centos.

How can I get data from InterSystems.Cache in this case?

As I understand it, InterSystems.Data.CacheClient.dll is only for the .NET framework.

Access to current line text

Is there a general way to set a variable XYZ equal to the text of the code line being executed now? Debugger or production. For example, for a code below if code is currently assigning a to 1, XYZ would be equal "S a=1". The same question about a variable containing current routine name.

S a=1

Hi everyone,
I am trying to create a listen server in Cache 2016 that can capture data from a specific port. Can someone guide me on how to set this up, including handling incoming connections and reading data from the port? Any advice or example code would be much appreciated!

Thanks in advance!

Hey everyone.

I'm currently looking at a process where we're utilising the Class Ens.StreamContainer, and was looking to do some deletions outside of any purge routines.

Having been burned before, I wanted to make sure that deleting the container also deletes the contents within.

From looking in the class, the %OnDelete ClassMethod appears to be removing an index from a search table and nothing more.
