#5003 not implemented

I am trying to create a scheduled task but get not implemented error when I try to run it.

Class PICIS.Core.Tasks.CleanEntry Extends %RegisteredObject
{

ClassMethod ClearTasks(pBackupFile As %String = "d:\Temp\BackupTasks.xml", pDelete As %Boolean = 0)
{
// Create backup file
Set tBackup = ##class(%Stream.FileCharacter).%New()

problem with Mirroring

Hello, Thanks in advance for all replies. I have been practicing setting up mirroring between two development servers in preparation for mirroring our production server in a few weeks. I started by setting the servers up with minimum security which worked easily, then I set it up in lock down mode again without any issues. Now I am setting it up in lockdown mode with encryption and this one is testing me. I have everything setup but my async dr member cannot connect to the primary.

Greetings! This article describes yet another simple way of creating installers for the solutions based on InterSystems Caché. The topic covers applications, which can be installed or completely removed from Caché with one action only. If you are still documenting installation instructions that have more than one step to do to install your application — it’s high time you automated this process.

Web Sockets

Hi

I am working on a project that will interact with some software called ROS (Robot Operating System). One of the development challenges we have is as follows:

ROS uses web sockets... So one connect with ws://localhost:9090 to the web socket server. It starts off as http, but then "upgrades" to web socket. It then keeps open this "tunnel" for bi-directional communication..

I need something like a HTTP Outbound adapter, but the Web Socket version of it...

Does anyone have any experience in this area?

Hi,

I am experimenting with Cache-Python binding. In the following piece of Python code

import intersys.pythonbind3

conn = intersys.pythonbind3.connection( )
conn.connect_now('localhost[1972]:SAMPLES', '_SYSTEM', '123', None)
samplesDB = intersys.pythonbind3.database(conn)
p10 = samplesDB.openid("Sample.Person",'10',-1,-1)
p10.run_obj_method("PrintPerson",[])

MAXSTRING limit issue

MAXSTRING (longstring) is enabled.

We have a Class containing a property definition

Property SettingsJSON As %Text(MAXLEN = 3600000)

The property is used for storing a string of JSON data however in some cases we get a Cache error: %SaveData error when trying to save a string of JSON a lot less than maximum "allowed" length, any ideas anyone?

Creating custom SNMP OIDs

This post is dedicated to the task of monitoring a Caché instance using SNMP. Some users of Caché are probably doing it already in some way or another. Monitoring via SNMP has been supported by the standard Caché package for a long time now, but not all the necessary parameters are available “out of the box”. For example, it would be nice to monitor the number of CSP sessions, get detailed information about the use of the license, particular KPI’s of the system being used and such. After reading this article, you will know how to add your parameters to Caché monitoring using SNMP.

Adding TLS to ZAUTHENTICATE

I wrote a ZAUTHENTICATE.mac a couple of months back, and found recently that it is creating coredumps on almost a nightly basis. I think I have figured out this problem to be not clearing out my MsgSearch after I am doing 2 of them within the code.

1. Get User Attibutes from AD

2. Get User Groups From AD

So while I am trying to cleanup the code I thought it would be a good time to add a Certificate and TLS to the mix since I should of been using that all along. However I keep running into issues

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.

Hi,

The following sql statement is working through the SMP but couldn't make it work through the code.

The table is a linked table to oracle db.

Tried to change the date property in the linked table class from %Date to %String and also tried using %SQL.Statement and %Library.ResultSet

this work through SMP:

INSERT INTO PACKAGE.SOME_TABLE_NAME

(EFFECTIVE_START_DATE,MORE,DATA,HERE)

VALUES (to_date ('2018-04-01','yyyy-mm-dd'),123,456,789)

In the code i'm using '?' in the statement for the parameters.

Please find the code writing to the csv given below.

Hi all,
By using VS code, I want to copy multiple files to local directory, then sync them to server, but I can't find where local directory is stored?
In Atelier IDE, I could open a view of server and can copy the code to the project, then code is saved in the local directory. When I copy multiple files to the local directory -> choose sync in Atelier -> the code will be synchronized to the server
How to do this from VS Code?
Thanks!

Something that shot up the popularity stakes last week was this article on a very interesting initiative: RealWorld:

https://medium.com/@ericsimons/introducing-realworld-6016654d36b5

I decided it would be a good idea to use this as a way of creating an exemplar implementation of a RESTful back-end using QEWD against their published API (https://github.com/gothinkster/realworld/tree/master/api)

The results are here:

Your application is deployed and everything is running fine. Great, hi-five! Then out of the blue the phone starts to ring off the hook – it’s users complaining that the application is sometimes ‘slow’. But what does that mean? Sometimes? What tools do you have and what statistics should you be looking at to find and resolve this slowness? Is your system infrastructure up to the task of the user load? What infrastructure design questions should you have asked before you went into production? How can you capacity plan for new hardware with confidence and without over-spec'ing? How can you stop the phone ringing? How could you have stopped it ringing in the first place?
