In the same way as you create an instance of any class:

ENSDEMO>set oInst=##class(Demo.Loan.FindRateProduction).%New()
 
ENSDEMO>zw oInst
oInst=<OBJECT REFERENCE>[1@Demo.Loan.FindRateProduction]
+----------------- general information ---------------
|      oref value: 1
|      class name: Demo.Loan.FindRateProduction
| reference count: 2
+----------------- attribute values ------------------
|  AlertActionWindow = 60
|AlertNotificationManager = ""
|AlertNotificationOperation = ""
|AlertNotificationRecipients = ""
|    ShutdownTimeout = 120
|      UpdateTimeout = 10
+-----------------------------------------------------

On this post the answer by @Dmitry Maslennikov might be useful for you.

By looking at the code of the InstanceGUID method in the %SYS.System class we can see where it's stored:

/// Returns instance GUID.
/// <br>
/// An instance GUID is a 16 byte (128 bit) globally unique identifier, assigned per instance of Cache installation.
ClassMethod InstanceGUID() As %String
{
    s ns="^^"_$zu(12)
    if ('$d(^[ns]SYS("INSTANCEGUID"))) Set ^[ns]SYS("INSTANCEGUID")=$system.Util.CreateGUID()
    Q ^[ns]SYS("INSTANCEGUID")
}

It's in ^SYS("INSTANCEGUID") in the CACHESYS database.

However I don't know what might happen if you change it. Best check with InterSystems.

I don't know if this is related, but recently when I've been posting images in new articles, or in answers or comments, I sometimes upload my standard filename (Capture.PNG) but the image that appears in the DC editor window is wrong. It often seems to be one that I've previously uploaded, though not necessarily my most recent previous upload. I delete it in the editor, repeat the upload, and it's usually OK the second time. I recall once having to do two retries. I'm using Firefox 53.0 on Windows 10.

Anyone else seeing this kind of event?

What Cache version are you running?

Are you editing code with Studio, Atelier, Serenji or some other tool?

Do you have any specific configuration management tools in mind? If not, have you looked at Deltanji?

Look at the methods of %SYSTEM.OBJ and in particular ExportAllClasses.

Your reference to LocalSystem means I assume you're running Cache on Windows. On this platform Cache processes started by Cache (e.g. telnet logins, web application handlers, Studio connections) will run at the OS level as whatever Windows account the Cache service is set to log on as (see Windows service control manager tab as shown below).

If you make your Cache service run as a specific account rather than as Local System, then all of the processes started by Cache will run with those credentials.

I don't know if this will help you.

UPDATE: Starting at 2015.2 (I think), it is important to use the cinstall.exe utility (located in your installation's bin subdirectory) to change which account the service runs as:

cinstall setserviceusername <InstanceName> <username> <password>

If you don't do this but instead only  change the setting in the Log On tab of the service (screenshot above), then in certain circumstances the $ZF() functions may return a -1 failure code. See http://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY… Search the docs for "setserviceusername" for more details.

It looks like the AutheEnabled property of Security.System is the equivalent. See class doc here.

Use the Get and Modify classmethods to fetch and update values.

If you're trying to check that the first character is " then you need to double the quotes. In other words, test as follows:

if $e(chunk,1,1)=""""

I expect it gets hit whenever an HTTP client accesses that URL.

I expect it will consume a license in the normal way.

Can you use web server logs to find out where the HTTP requests are coming from?

Also, is this a duplicate of a previous question from you?

As you're asking about an outbound connection, I'm not clear what you mean by making HealthShare "use the virtual IP address" of your 2-server Windows cluster. Please explain.

Maybe adding the /recursive=1 qualifier will give you what you want. If so, please click the checkmark to accept this answer.

Excellent discussion starter Sean. But does your third sentence need a little debugging? You wrote (my highlighting):

It's not because I don't dislike them...
