#Caché

MessagePack is a binary-based efficient object serialization library. It enables to exchange structured objects between many languages like JSON. But unlike JSON, it is very fast and small.

Any chance of adding support for MessagePack?

Hello Fellow Cache Developers:

Has anyone ever created an index on values of a list property? If so, would you be willing to share an example?

Also, feel free to offer input and suggestions regarding use of indexes on List values.

Here is my database scenario:

Parent Class:

PropertyA - %String

PropertyB - %Integer

Child Class:

PropertyC - %Integer

PropertyD - list of %Integer

Data illustration:

Hi All,

SPOOLER functionality is support in Cache 16?
Previously we are using cache 5,Now we upgraded cache(cache 16).
Is any changes required in SPOOLER set-up (Cache 16)?

Thanks,

Hi, Community!

We have our internal backup system which produces *.cbk files for Full, Incremental and Cumulative backup modes.

Does anyone have an automation procedure to restore this files on some target testing system, check the integrity and mark the files as "restorable"?

Please, share?

Thank you in advance!

Well I want to set the type of a piece in a global as a String, because when I use float numbers , the system parse them to numbers instead of use like strings and thats a little bit tricky with the sorts

Here is a code example:

ACB>s ^a("1.0012")=""// that is going to be stored as a number

ACB>s ^a("1.0011")="" // that is going to be stored as a number

ACB>s ^a("1.0010")="" // that is going to be stored as string

ACB>zw ^a

^a(1.0011)=""

^a(1.0012)=""

^a("1.0010")=""

I am trying to set up a sensor in PRTG to connect to Cache, specifically the ens_util.log, so that I can have a live feed of my error count. I am having trouble getting the sensor to log in to Cache. Has anyone had any luck getting PRTG to connect on the database level? Thanks!

Is there any methods/ways through which will get to know whether any of the Unit Test cases is/are failing in the Terminal with status as either 0 or False in case of Failure & 1 or Ture in case of Test Passes (we are getting an url of the csp page with the report which has the passed failed status) as we need to send this failure status to Jenkins for the Build to Fail (where in we have acheived this part in making the build failure/success based on harcoded boolean)

Have very little XML experience and have been able to manually create output. Have a need to take data that I store in a M global (example: ^TML("HDATA", ) and out put it in CCDA XML format.

Are there any examples of M code using the XMLWriter to accomplish this?

Or can anyone provide some guidance

Any help would be greatly appreciated.

When you first start working with InterSystems IRIS, it’s a common practice to install a system with only a minimum level of security. You have to enter passwords fewer times and this makes it easier to work with development services and web applications when you're first getting acquainted. And, sometimes, minimal security is more convenient for deploying a developed project or solution.
And yet there comes a moment when you need to move your project out of development, into an Internet environment that’s very likely hostile, and it needs to be tested with the maximum security settings (that is, completely locked down) before being deployed to production. And that’s what we’ll discuss in this article.
For more complete coverage of DBMS security issues in InterSystems Caché, Ensemble, and IRIS, you may want to read my other article, Recommendations on installing the InterSystems Caché DBMS for a production environment.
The security system in InterSystems IRIS is based on the concept of applying different security settings for different categories: users, roles, services, resources, privileges, and applications.

Users can be assigned roles. Users and roles can have privileges on resources — databases, services, and applications — with varying read, write, and use rights. Users and roles can also have SQL privileges on the SQL tables located in databases.

Hi,
Trying to work with REST protocol, using IIS 8, both client and server are Cache servers,
I have the following problem-
When I send a PUT command, I get the following error:
<HTML><HEAD><TITLE>Length Required</TITLE>

<BODY><h2>Length Required</h2>
<hr><p>HTTP Error 411. The request must be chunked or have a content length.</p>
</BODY></HTML>

Hi community members!

Please, I'm looking for any references or experiences using InterSystems technologies with MQTT (Message Queuing Telemetry Transport) protocol .

Thanks in advance!

Hello,

I have a question about creating properties with curl.

I already did create properties in Java with the following command.

<DO db.%CreateProperty("TotalSteps","%Integer","$.TotalSteps")>

It created the property TotalSteps with the type %Integer and the data path $.TotalSteps (since the header of my data source is also TotalSteps).

Now I would like to create the same property in curl with the following command

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
