#Mapping

3

Mapping of classes, routines, globals to Namespaces.

My dilemma is that I'm working with a file that has three different data records plus the header and trailer.  The record type is in positions 21-23.  The header and trailer have spaces in positions 1-20.  The data records have a variable data in positions 1-20.

SQL for ^ERROR Global 
This is a coding example working on Caché 2018.1.3 and IRIS 2020.2 
It will not be kept in sync with new versions 
It is also NOT serviced by InterSystems Support !

Standard error logs in IRIS / Caché / Ensemble are written global ^ERRORS.
As this piece dates back some decades back to previous millennium its structure
is far from the typical SQL storage structures.

I'm trying to setup a REST server with CORS support. I have created a class that handles a specific part of the service (printer control). This class I have referenced in my main REST class by adding <Map Prefix="/print" Forward="myClass.PrintAPI" />

My main class does have its own <Route>s and handles CORS requests perfectly. But in my subclass OnHandleCorsRequest() is only run when requesting from same origin and never run when making a CORS request. I have set Parameter HandleCorsRequest = "true" in both my main REST class and the subclass.

Hello,

I like to know if we need to have the message in a file to process a Record Map?

I am working with Interoperability Production that processes files /messages using Record Maps. My team was asked to redesign the solution for deployment in AWS. We use containers. We had problems with having multiple containers processing files from the same directory. We are considering Amazon Simple Queue Service instead of having files on a shared file system.

When I start a fresh installed IRIS or a Container I always find Interoperabiliy (aka. Ensemble) mapped to namespace USER.

Is there any utility to remove this mapping by a click ?
unmapping it global by global, routine by routine,  Package by Package is just a boring exercise.

To be clear: I look for a utility inside IRIS.

The external utility is obvious: Notepad (or any other text editor) 
- clean iris,cpf,
- restart IRIS
It's fast, it's efficient, but it's really hardcore.

If two globals have same structure, how to reuse one CacheSQLStorage-based class to read both locations?

Thanks!

Update:

Let's say we have two globals:

^a(1)="dataa1"
^a(2)="dataa2"

and

^b(1)="datab1"
^b(2)="datab2"

i.e. the structure difference is global name only.

I would like to have two classes TableA and TableB both are inherited from TableAB, and TableAB taking global name as a parameter.

Semi-Persistent Classes and Tables

If you define a Persistent Class / Table the class compiler generates for you an appropriate Storage definition.
A different option is to define a SQL mapping for an already existing Global storage.  This has been excellently
explained already in a different series of articles.   The Art of Mapping Globals to Classes 1 of 3
