I'm connecting to a remote device using TCP. It has a binary protocol.

set host = ""
set port = ""
set io = $io
set device = "|TCP|7000"

set timeout = 2
open device:(host:port:"M")
use device:(/IOT="RAW")
read string:timeout

use io
zzdump string

The problem is when reading from it, I get a 0A (also known as 10 or \n or linefeed) byte, which terminates the read.

Expected output:

0000: 42 00 7B 0A 11

But I get this output:

0000: 42 00 7B

How can I fix that?

 

Some additional info:

  • read completes in 0.1 seconds despite 2 seconds timeout.
  • $zb contains the value of 0D

1. Blockchain

As I am writing this article, Bitcoin costs less than one-fifth of what it used to be at the pinnacle of its success. So when I start telling someone about my blockchain experience, the first thing I hear is undisguised skepticism: "who needs this blockchain stuff now anyway?"

That's right, the blockchain hype has waned. However, the technologies it is based on are here to stay and will continue being used in particular areas.The Internet in general offer tons of materials describing the general usage of these technologies

WebSockets as a communication technology wins increasing importance.
In the SAMPLES namespace, you find a nice example for running a WebSocket Server.
There is also a useful example for a Browser Client. But it is still in the browser. 

My point is:
How to consume the output of a WebSocket Server in your application?

Hi All,

I created a Business Operation to Integrate with Amazon S3.
I have used HTTP Outbound Adapter for the same. Used Get method of Adapter Class.
Basically in a request I want to send Unique File Name and File and in Response I want to get Version ID and if operation was successful, then set flag to true.

I have created a class for request in that I have two properties, as shown Below :
   

    Property fileName As %String;
    Property file As %GlobalBinaryStream;

This is in my Operation Class
 

            set pResponse = ##Class(SaveFileResponse).%New()
            set fileName = pRequest.fileName
            set file = pRequest.fil

Hello Cache Developers:  I was curious if anyone has ever created a TWAIN interface to their Cache Application?   I am new to TWAIN and hence the reason for this question.  From what I understand, TWAIN is software used by various digital imaging software and TWAIN provides an API for applications to call to be able to import images into their application.   I work with a healthcare application and was wondering what types of things are required for a Cache Web Application to call the TWAIN API to be able to load images into a Cache table.    Any input, sample code, or suggestions is appreciated.   Thanks and Have a Great Day!    Happy Coding.

Running predictive models natively in an InterSystems IRIS Business Process has of course always been the goal of our PMML support, but somehow never made it into the kit because there were a few dependencies and choices that needed addressing and answering. Anyhow, thanks to some pushing and code kindly provided by @Amir Samary (Thanks again Amir!), we finally got it wrapped in a GitHub repo for your enjoyment, review and suggestions.

This post is intended to guide you through the new JSON capabilities that we introduced in Caché 2016.1. JSON has emerged to a serialization format used in many places. The web started it, but nowadays it is utilized everywhere. We've got plenty to cover, so let's get started.

Hi,

I need to route a message synchronously to multiple targets using a routing rule.

In IRIS I built a general routing rule set, made up of a couple of rules. For one Rule in particular, and based on a common condition, I want to send the incoming message to 2 different targets. (no transformation is used)

I can select, in the single SEND action, multiple target names, or, I can create consecutive SEND actions, one after the other, each sending to their specific target.

The issue I have is that I want to do this routing synchronously, and only send the document to the second target, after the first target has finished processing (returns some response).

I know that - rather than using a routing rule, I can use a Business Process, however, I was hoping to avoid that if I can.

Any ideas how to send synchronously from a generic routing rule ?

Thanks - 

Steve

Hi,

I ran into the Issue https://hibernate.atlassian.net/browse/HHH-10620. The workaround  described at https://community.intersystems.com/post/support-java-hibernate-5 worked for me. I'm using Hibernate Version 5.3.2.Final.

It would be nice if someone from InterSystems could fix the the problem in Hibernate. That was mentioned in https://community.intersystems.com/post/support-java-hibernate-5 but it doesn't seem to have happened.

Ive been asked to investigate Intersystems Cache' for a new software initiative and was hoping to be able to download a limited-use or dev license to kick the tires but I need it for a couple of specific OS builds.  AIX and Linux (CENTOS).  I don't see a place to download specific versions, other than Windows, various builds of Unix and that's about it.  Can someone give me some guidance on how to make sure I'm downloading the right item to build some test instances with?  

thank you in advance :)

This is a FYI for anyone who has experienced the following error after upgrading an existing  instance to any product based on Caché 2017.2.2. In our case, the products are HealthShare HealthConnect for Redhat x64 and for Windows x86-64 but I believe it would be a common problem for any InterSystems product on any platform, if based on Caché 2017.2.2. After upgrading our development instance from 2016.2.2 to 2017.2.2, we experienced the following errors when attempting to start a pre-existing Java Object Gateway that was defined prior to the upgrade:

Execution returned: 'Error: Could not find or load main class '

*ERROR* Return from StartGatewayObject: ERROR #5001: There were errors returned when trying to start the Java Gateway

An error occurred while trying to start the Gateway Server

I want to call java method and return $lb structure from it.

JDBC jar seems to contain relevant class -  com.intersys.jdbc.CacheListBuilder, but so far I only managed to return a string that looks like a list.

Here's my java code:

package isc.poi;

import com.intersys.jdbc.CacheListBuilder;
import java.sql.SQLException;

public class Test {

    public static String Test() throws SQLException
    {
        CacheListBuilder list = new CacheListBuilder("UTF8");
        list.set(123);
        list.set(456);
        list.set("\"abc\"");

        return list.toString();
    }
}

And Cache part

I'm working on a task where I need to apply journal file records to another database. I can't use Journal.Restore class methods as I need to perform some data transformation, therefore I'm reading journal file record by record using %SYS.Journal.Record API.  

It seems that there are only few journal records that I need to process, namely:

Type TypeName
6    SET
7    KILL
8    KILLdes
9    ZKILL
10   RemoteSET
11   RemoteKILL
12   RemoteZKILL
14   BitSET

No problem, while I'm just curious: which COS command could provide KILLdes record? I've met it only once in the context like this:

KILLdes ^SYS("Task","TaskD",1006,"EmailOnError",1)

I can't imagine that Caché is smart enough to recognize the command series

Hi - has anyone successfully used the python binding on a mac. I carried out the install instructions per InterSystems documentation and it fails completely. 204 warnings and 9 errors. Obviously this was never tested by InterSystems. Is it even worth pursuing?

Thanks

Managed File Transfer (MFT) feature of InterSystems IRIS enables easy inclusion of a third-party file transfer service directly into an InterSystems IRIS production. Currently, DropBox, Box, and Kiteworks cloud disks are available.

In this article, I'd like to describe how to add more cloud storage platforms.

Here's what we're going to talk about:

  • What is MFT
  • Reference: Dropbox
    • Connection
    • Interoperability
    • Direct access
  • Interfaces you need to implement
    • Connection
    • Logic
  • Installation

There are numerous ways to interact with InterSystems Caché: We can start with ODBC/JDBC that are available via SQL gateway. There are API for .NET and Java too. But if we need to work with native binary libraries, such interaction is  possible through Caché Callout Gateway, which can be tricky. You can read more about the ways of facilitating the work with native libraries directly from Caché in the article below.
