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

getting "The value of the property 'cspHttpServerMethod' is null or undefined, not a Function object" error while executing the csp page. All the server side methods stop working at this time although javascript functions still work but until the point where a server side method is getting called. Any clues why we get such error.

Hi all,

I've a RESP API service in a Business Service to server different methods

I've created the route with the name of the method, each one has been created in lowercase 

XData UrlMap [ XMLNamespace = "http://www.intersystems.com/urlmap" ]
{
<Routes>
    <Route Url="/user" Method="POST" Call="User"/>
    <Route Url="/emailactivation" Method="POST" Call="EmailActivation" />
    <Route Url="/login" Method="POST" Call="Login"/>
</Routes>
}

But only there is a response if the call is used in lowercase

You might find it useful or not. It depends on what you can imagine it to be used with, like I had to.

Either way, I created a lib that can fetch environment variables from a file or from the OS where Caché is running.

Mostly know as dotenv. Many languages have it, so why not Caché?

The usage is pretty simple:

If you want to use OS env vars exclusively, just use the method:

Good day, every process in my software is about to update 3 specific globals in row when the process is called to do some job. I need to guarantee that during updating of those globals with multiple processes there is only one process that is actually working with those globals. Moreover I need my globals unreadable if other process is in critical area.

Hi guys!


Unique, PrimaryKey and IDKey?
In what contexts does it apply?

IDKey sets the registry key access to the store.
PrimaryKey, Unique, and IDKey define the uniqueness in the records, but what is correct?

I use everyone? What is the context of each?

Back in my COBOL days, there was a utility that would analyze running COBOL code and expose bottle necks and those modules that were inefficient or were executed multiple times. This was to help the programmer know where to concentrate streamlining efforts.

Is there any such utility for Caché Routines?

Hi,

We have a application developed in CSP and JS. Is there any way to make this application available in multiple language like Spanish etc.

We are ready to re-write the code in Zen also if it supports that feature.

Could any one of you please assist/advice a Solution to reach the required goal using Cache technologies, it will be a great help if someone has any sample code for the same.

Thanks

Paras

Hi,

After restoring all the Cache related files on a machine, I am performing journal recovery using the command "^JRNRESTO". It works as described in the document and the recovery succeeds. However, the command is interactive. Is there a way I can run it in a programmatic way? I don't want to just supply a text file containing answers to all the prompts. I am wondering if there is way I can pass all the information upfront to the command.

Thanks,

Raghu
