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

Documentation.

I'm using a %Net.HttpRequest which had been successful in the past, but started failing at some point with a SSL/TLS protocol error.

ERROR #6085: Unable to write to socket with SSL/TLS configuration 'groundca', error reported 'SSL/TLS error in SSL_connect(), SSL_ERROR_SSL: protocol error, error:14077102:SSL routines:SSL23_GET_SERVER_HELLO:unsupported protocol'

The SSL/TLS configuration:

when doing ETL process from cache database to mysql database(ods) and to another mysql database(dwd).

There are lots of DR columns in one table.

In the first step we need two databases to be totally consistent(ods=cache database)

However, the DR column in another database lost its meaning and become to normal number.

In the last step we do the data governance in ODS to DWD. My question is how to write sql without many `join` in this step.

Is it possible to audit code changes in a namespace?

Ideally what we'd like to be able to do is check which classes were compiled (or deleted) in a time period, eg in last 3 months, and which user made those changes. Even better would be an audit of what those changes were, but that's less important (for us, as we can probably find that information in other ways).

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.

Error Compiling class

Hi,

When I try to compile a specific class it fails and gives the below error message.

ERROR #5002: Cache error: <FUNCTION>zLockUse+5^%ExtentMgr.GlobalRegistry.1
> ERROR #5030: An error occurred while compiling class 'ClassNameHere'

Is there anything I can do to fix this issue?

Thank you in advance for your response.

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?

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!

Hi Community,

I have a problem I am hoping someone can help with - I have created a front-end with HTML/CSS/JS in a CSP page in Iris Studio. I am trying to use objectscript on the back end to connect to a SQL Server Database (with valid credentials), and execute a stored procedure.

I have a fileList variable that is a stored as a comma separated string through a user input textBoxContainer. This is to be used as a parameter in the stored procedure called @Docs

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.

Using Cache 2017.2 sever as my target.

I have a x64 Ubuntu client setup going. This is NOT server. Just client.

I have the Linux Ubuntu x64 ODBC driver gzip file.

ODBC-2018.1.5.659.0-lnxubuntux64.tar.gz is all I could find. Someone posted it in another post.

I can connect to a test sever that does NOT use SSL. That works pretty easily.

But I have A server with SSL enabled. With Windows Cache ODBC drivers I can use SSL just fine.

This is what my SSLDefs.ini file on the Windows machines look like and it works just fine.

When using standard SQL or the object layer in InterSystems IRIS, metadata consistency is usually maintained through built-in validation and type enforcement. However, legacy systems that bypass these layers—directly accessing globals—can introduce subtle and serious inconsistencies.

Error importing XSD

I'm attempting to import all the FHIR XSD files provided by http://hl7.org/fhir but get the immediate and unhelpful error message:

I've tried different versions of EOLs to no avail. Any idea what this error could mean?

Here's the XSD I'm trying to import:

I'm trying to open a TCP connection to a remote system. The Caché command I'm using to open the connection is OPEN "|TCP|"_PORT:(IP::"PSE"):10 where PORT is a port number in the range 40000 to 40100 and IP is a standard IPv4 addess like 10.200.100.50
the connection appears to open because $TEST becomes 1.
I'm then writing to the open port with USE "|TCP|"_PORT:(::"S") WRITE "some text",*-3
It's a windows system

Hi everyone,

I'm working with JavaScript in InterSystems IRIS, specifically in CSP pages. One issue I'm running into during development is that the browser keeps loading the cached version of my JavaScript files, even after I’ve made changes or recompiled the code.

I would have to clear my cache files or browser history for it to reload and work.

I am trying to get the value of a Submit button on a CSP object page.

<input type="Submit" value="Assign" name="action" id="action">

I tried getting it thru $GET(%Request.Data("action")), but it throws an Undefined error. Isnt $GET supposed to handle it if its undefined anyway?

How do I get the "value" of the button pushed when the form is set to POST?

I like Application Error Log a lot, both for its full stack and a big list of variables. I'd like to "hack" this functionality and record the same in this log when a certain variable has a certain value. This quasi error should not be visible to the user, and it should not interrupt the application flow. Is that possible?

Throwing an error in a try-catch block does not record the error, tested. I am considering recording variables and the stack differently, I know how to do both, but that would miss the nice Application Error Log functionality.
