#Caché

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?

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.

A function iterates global ^data(a,b,c) with $order using 3 nested for-loops. At certain point, for example with a=10, b=20, c=30, the function exits and later has to resume the iteration from the same point. What could be easiest way for it? My solution looks too ugly.

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,ererybody!

help,

how to use M language get local Computer MAC Address?

I know get local ip use : w $ZU(67,15,$j),but i don't know this.

Hi

Upon creating namespace I selected same database for both Globals and Routines. How can I separate both the databases. Please note that I already have data and code saved in database.

Thanks

I keep seeing <INVALID OREF>zMyproperty<

Hi,

I have written a procedure with the help of object scripting to export data to a csv file. There is more data than the csv limit.

Can anyone please tell me how to get the row count of csv file using object scripting, so that I can write an if condition and write to a second csv file.

Please find the code writing to the csv given below.

Let's suppose two different routines use one and the same chunk of code. From the object-oriented POV, a good decision is to have this chunk of code in a separate class and have both routines call it. However, whenever you call code outside of the routine as opposed to calling code in the same routine, some execution speed is lost. For reports churning through millions of transactions this lost speed might be noticeable. Any advice how to optimize specifically speed?

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:

I understand this is a rather broad topic (and at times involves religious sentiments) yet I would like to look at it from the Caché perspective:

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()
Set tBackup.Filename = pBackupFile
Do tBackup.WriteLine("<?xml version=""1.0"" encoding=""UTF-8""?>")
Do tBackup.WriteLine("<Tasks>")

How would I export the WHOLE PROJECT rather than just a single class file out to an XML file?

I would like to, on every file change export the whole project to XML

Thanks for your time

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.
