#Caché

In recent discussion on CachéQuality I was (friendly) blamed for old syntax promotion and deliberate obfuscation of the code. Therefore I decided to clarify my point and shed some light on one of possible source of side effects that may unexpectedly occur with RETURN command with an argument.

March 14, 2019 – Alert: Data Integrity Issue with Mirror Database Catchup

InterSystems has corrected a defect in our mirroring technology that can result in inconsistency between mirrored databases. This defect exists for currently released Caché and Ensemble versions beginning with 2017.2 and for InterSystems IRIS Data Platform version 2018.1.

When the issue occurs, some journal updates are not applied to a mirrored database on the backup mirror member or an async member that is being caught up.

How can a remote webserver be configured to access the application on a different application server ?

Example: customersdomain.com running on the customer's server, to access the csp application running on the service provider's own server ?

Hi there,

    I'm trying to develop a  program calling Cache REST service twice with Cors. The first is fetching some information of a patient with GET request, the second is using obtained information to call another REST service(implemented in the same class though) with POST to  perform other tasks.

what is the bullet point char value in COS the equivalent of •

Sometimes global mapping of the same globals can be defined in different ways. E.g., I need to define it for 3 globals ^qAuditC, ^qAuditLog, ^qAuditLogC from the same database named APP-NOJOURN. Which approach should be better from the performance point of view?

1) qAudit* => APP-NOJOURN (one record in global mapping table)
or

2) qAuditC => APP-NOJOURN
qAuditLog => APP-NOJOURN
qAuditLogC => APP-NOJOURN (three records in global mapping table)

From one hand, the less records in global mapping table, the better. From other hand, * can cause additional processing at run time.

Why  method and class method are different? . What is the purpose for using these are seperatly?

ClassMethod Test(){

}

Method Test() {

}

I need to start doing unit testing for some of my code.

Why does it delete the unit testing class from Cache when I run the test?

Is there a way to turn this off?

Class User.samplexlsconversion Extends (%Persistent, %Populate) [ Owner = {_PUBLIC} ]
{
Property name As %String;
Property DOB As %Date;
Property address As %String;
Property PhoneNumber As %Numeric;
Property BloodGroup As %String(DISPLAYLIST = "", VALUELIST = "A A- B B- O");
ClassMethod ExtractXls()
{
               Set file=##class(%Library.File).%New("C:\Users\Ponnumani\Desktop\Ponnumani Tasks\file.csv")
               Do file.Open("WSN")
               Do file.

Is there a quick way to see if an SSL/TLS configuration name is valid, short of switching over to %SYS and checking Security.SSLConfigs:Exists?

InterSystems Data Platform includes utilities and tools for system monitoring and alerting, however System Administrators new to solutions built on the InterSystems Data Platform (a.k.a Caché) need to know where to start and what to configure.

This guide shows the path to a minimum monitoring and alerting solution using references from online documentation and developer community posts to show you how to enable and configure the following;

1. Caché Monitor: Scans the console log and sends emails alerts.

2. System Monitor: Monitors system status and resources, generating notifications (alerts and warnings) based on fixed parameters and also tracks overall system health.

3. Health Monitor: Samples key system and user-defined metrics and compares them to user-configurable parameters and established normal values, generating notifications when samples exceed applicable or learned thresholds.

4. History Monitor: Maintains a historical database of performance and system usage metrics.

5. pButtons: Operating system and Caché metrics collection scheduled daily.

Remember this guide is a minimum configuration, the included tools are flexible and extensible so more functionality is available when needed. This guide skips through the documentation to get you up and going. You will need to dive deeper into the documentation to get the most out of the monitoring tools, in the meantime, think of this as a set of cheat sheets to get up and running.

Hello.

There is a way to install and try Cachè 2018.1 on Ubuntu 16.04 distribuition or it's necessary use Red Hat/Suse distribuition to try Cachè on Linux?

Hi Community,

I have to make a daily task (Job) which will run (7 am to 7 pm) in a day at an interval of 3 hours. Timings are as (7:00 am, 10:00 am,13:00 pm,16:00 pm,19:00 pm). But at each time when task will run i have to set a variables as per below condition

Sample:

1) If task run at 2019-03-19 07:00 am in morning

I  have to set two variables (start and end) whose value will become like this

(set starttime= 2019-03-09 07:00:00.00 and set endtime=2019-03-09 10:00:00.00)

2) But if task run at 2019-03-19 10:00 am in morning, the value should change as per below

(set starttime= 2019-03-09 10:00:00.

Hi all,

Lets imagine that there's a process that locks an entry of a gived domain, in my example the ID 2 of the table User.tApplications and using an exclusive lock.  Additionally the error handling is managed by a $ETrap routine wich will look for error data in order to log it

Set $ETrap = "Do Err1^ErrRoutine"

Set obj = ##class(User.tApplications).%OpenId(2,"4",.errors)

If ($System.Status.

Hi community,

I have a rights problem when giving a user permission to perform some select queries on particular tables. So I have created a user with the following rights.

So this all works well. No problem so far. But the customer is using a program where you can easily build visually the query by selecting the table, choose the right colums etc. So the problem we have is when I give the user the Role %All the tables are shown.

And the user is allowed to query all tables.

Can I apply a custom resource to a Management Portal page through code, using the method or global? The documentation only shows the manual mode: https://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY=GCAS_rsrcs#GCAS_C181701

Or export the settings already saved.

I have a cache client trying to call a web service using  SOAP version 1.2.  We receive a SOAP error with the following text:

COD>w ##class(DBMS.Tools).DecomposeError(%objlasterror)

ERROR #6248: SOAP response is a SOAP fault: <Fault><Code><Value>s:Sender</Value>

<Subcode><Value>a:ActionMismatch</Value></Subcode></Code><Reason><Text xml:lang=

AP Action, 'siad.tpic/ITpicDefaultService/Audit'. </Text></Reason><Detail><a:Pro

From the documentation for SOAP 1.

This code snippet is an example of a CSP page that has a dynamically reloading table:

Hi All,

Can any one know how to change the font style as Italics in Terminal

Hi Community!

There are two general ways to execute arbitrary SQL  in serverside ObjectScript code: EmbeddedSQL and ObjectScript SQL a.k.a. Dynamic SQL.

E.g. if we want to get the value of the property of instance with a certain ID using SQL we can do:

&sql(SELECT Name INTO :name FROM Sample.Person WHERE ID=1)

write name

Same result with %SQL.Statement:

set rs=##class(%SQL.Statement).%ExecDirect(,"SELECT Name as name FROM Sample.Person where ID=1")
  do rs.%Next()
  write rs.name

Let's imagine you have only SQL. You need some table where you should increment value in some property when you update this line.

We have the table

CREATE TABLE "test" (
  "identifier"   VARCHAR(200) NOT NULL,
  "value"        INTEGER,
  PRIMARY KEY ("identifier")
)

Hi, 

what is reason of this error (Not all parameters bound/registered ). this is not happening consistently.

those are class method parameters

Query GetWorkItemsByEncounterID(encounterID As %Integer, userId As %Integer, IsSuperOrDev As %Integer = -1, facilityAccessListCSV As %String(MAXLEN=32000), locationAccessListCSV As %Library.String(MAXLEN=32000), skipReferralFilter = 0) As %SQLQuery [ SqlName = spGetWorkItemsByEncounterID, SqlProc ]
 

After compilation of routine .int file is not generated and toggle breakpoint is also not visible for that routine. It is showing error #5001 Editing of INT file is not allowed. How can I resolve this ?

Just wondering an Insight in the difference between these two indexes

IdKey / PrimaryKey
================= 

Property Identifier As %Integer

Index Index1 on Identifier [Idkey]

Index Index2 on Identifier [PrimaryKey]

What's the difference?

1. If I don't have Index1 and only have Index2,  then cache does still make its own id.
So how and why  do I ever use the PrimaryKey.  In Joins ??

Table1.Identifier = Table2.Identifier instead of Table1.Id = Table2.id ??
But I can still use Table1.Id = Table2.Id as cache still made one ID field

So where is PrimaryKey useful in cache?

Hi

Just curious to know about the pros and cons of Parent/Child Vs One/Many.

We do use a bit of both. 
One big reason we use Parent child is we feel if we delete one global, it gets rid of all child data too and all parent child data is stored in one global. Much easier to manage.

I know it's late, but I really love the advent of code theme each year to find some project ideas to go out and code something and push myself.

I had the intentions of completing the AOC 2018 before the new year, but I've got 2 young kids (1yo and 4yo), so most nights I just want to sleep.

I've been looking at this on my half hourly commute each day before and after work.

So whilst doing this, I found not many people had posted what they had done and in previous years.

I have one abstract class and several subclasses. All share one data/id global.

How can I get concrete class name from id (without opening the object)?

What I have so far:

write $p($lg(^DATAGLOBAL(<id>),1),"~",*-1)

It does the job, but is there a more official way?

I have a problem,ExtentSize,Selectivity etc is stored in class definition.

I have multiple namespaces with globals maped and only one class definition for All, for example Orders.

Order definition is only one,mapped to main namespace,but in different namespaces have different ExtentSize etc.

Here's a simple indirection snippet. It fails with <UNDEFINED> error and I'm not sure why.

ClassMethod ind()
{
  kill info

  set active = 1
  set reactive = 2

  for i="active","reactive" {
    set info(i)= @i
  }

  zw info

  break
}

I'm getting this exception: <UNDEFINED>zind+5^test.Client.1 *active

In this series of articles, I'd like to present and discuss several possible approaches toward software development with InterSystems technologies and GitLab. I will cover such topics as:

• Git 101
• Git flow (development process)
• GitLab installation
• GitLab Workflow
• Continuous Delivery
• GitLab installation and configuration
• GitLab CI/CD

In the previous article, we covered Git basics, why a high-level understanding of Git concepts is important for modern software development, and how Git can be used to develop software. Still, our focus was on the implementation part of software development, but this part presents:

• GitLab Workflow - a complete software life cycle process - from idea to user feedback
• Continuous Delivery - software engineering approach in which teams produce software in short cycles, ensuring that the software can be reliably released at any time. It aims at building, testing, and releasing software faster and more frequently.
