Ran into an issue with our upgrade from HealthShare Health Connect 2018.1.3 to IRIS HealthShare Health Connect 2022.1, that I thought I would reach out about, I already have a ticket open with WRC and started a chat on Discord. We have a couple of MS SQL tables that I have setup as Linked Tables within Cache to query NPI, Patient Account Information, Visit information, etc... When we upgraded last week we found that within a day or even a half a day that we were having problems with our JDBC connections.

Upon investigating with WRC we were able to track it down to our Queries against Linked

Several steps should be done in order to secure the connection through xDBC clients to an IRIS Server instance using TLS. Most of the information can be obtained from the documentation about TLS on IRIS here, about configuring the security layer for encrypted connections. In the next paragraphs we will cover an step-by-step guide on how to configure and test the connection using SQL Clients apps using ODBC and JDBC.

You can download the drivers from InterSystems IRIS Driver Packages

In this article, we will establish an encrypted JDBC connection between Tableau Desktop and InterSystems IRIS database using a JDBC driver. While documentation on configuring TLS with Java clients covers all possible topics on establishing an encrypted JDBC connection, configuring it with Tableau might be a little bit tricky, so I decided to write it down.

Securing SuperServer

Before we start with client connections, you need to configure SuperServer, which by default runs on port 1972 and is responsible for xDBC traffic to accept encrypted connections. This topic is described in the documentati

Hi all,

I'm trying to use LOAD DATA to insert 11k (11,377) rows of data. LOAD BULK DATA is not available for the version of IRIS I am using.

After calling LOAD DATA it says only 5,500 rows has been inserted. The LOAD DATA docs says any error rows are skipped and a count of skipped rows can be found in %SQL_Diag.Result however there are no results here. There are no errors in the xDBC error log either.

Why have over half the rows been skipped?

Hi,

Does anyone have experience with connecting to IRIS with OLEDB through an OLEDB-ODBC bridge? In this case the client can only speak OLEDB at this moment.

WIN SQL is the normal editor used by most of the users .But we can't download large amount of data using winsql . So I have written a tutorial how to connect with a new Java based editor called Squirrel SQL which can easily download or export data in excel or any other formats. Also I included a Java JCBC connection program to connect with the IRIS database especially a mirroring/failover server.

Hello,

I have a question regarding the Intersystems Caché Database and its jdbc driver. I need to set the connection timeout for the database, but I couldn't find any documentation stating that the jdbc driver for Caché supports setting the connection timeout. However, I noticed that the jdbc driver for the Intersystems Iris Database appears to support this feature.

My question is, can I use the Iris jdbc driver to set the connection timeout for the Caché Database?

The jdbc driver I use: cache-jdbc-2.0.0.jar

Thank you for your help.

Best regards,
Kalle

SSH framework is a relatively representative framework of Java, which was popular many years ago. There are Struts+Spring+hibernate and Spring MVC+Spring+hibernate. Of course, I used the second one in college. If I can connect IRIS to Hibernate as a library, does it also mean that IRIS can be developed using SSH framework in theory?

Dear community members!

A very common problem of our users is to use an external database as data source in an IRIS production. As many of you already know, we have two ways to connect directly to an external database, the first one is using an ODBC connection, the second is using JDBC.

In our example we are going to create a connection using JDBC, and we are going to build a simple Docker's project, in this way you will be able to modify the example as you wish.

The code is available from this URL: https://github.com/intersystems-ib/workshop-sql-jgw

In our docker-compose.yml file we are going to

The last days I've work with the great new feature: LOAD DATA With this post I would like to share my first experiences with you. The following points do not contain any order or other evaluation. These are only things that I noticed when using the LOAD DATA command. It should also be noted that these points are based on the IRIS Version 2021.2.0.617 which is a preview release. So it may be that my observations do not apply to newer IRIS versions. But maybe they are helpful for others.

1) The file path is on server side

I have done my first tests via JDBC.

Introduction

There are many entities in IRIS which are extremely difficult to transfer to another system.They usually contain important system-stored objects: users, roles, privileges, mappings, and applications. The exception to this list is for resources, which are facilitated by the ability to select and save them from the management portal interface [System > Security Management > Resources]. Yet, things are not as good with other system objects. I even got an idea for this topic

I devoted this article to the explanation of how to transfer gateway connection settings [System >

I am trying to troubleshoot an issue I am having with the JDBC Gateway Server crashing at the %SYS level. I have numerous Linked Tables that are using JDBC to connect to a MS SQL database/tables to query values. I have written queries in other class files and within the class definition of the linked table to do the queries.

1. Should I be running the query in the class definition of the linked table as a class method? or is it best practice to run the query as a class method outside of the class definition of the linked table?

2. I was reading documentation and came across the Config.Gateway SQ

I just wrote up a quick sample to help a colleague load data into IRIS from R using RJDBC, and figured it's worth sharing here for future reference.

Ultimately it was pretty simple, aside from IRIS not liking "." in column names; the workaround is to just rename the columns. Someone better at R than me could probably provide some generic approach. 

# Need a valid value for JAVA_HOME prior to calling library(RJDBC)
Sys.setenv(JAVA_HOME="C:\\Java\\jdk-8.0.322.6-hotspot\\jre")
library(RJDBC)
library(dplyr)
# Connect to IRIS – needs path to InterSystems JDBC JAR in your installation

I was attempting to test a Linked JDBC View to MS SQL database and noticed I could not connect. When I look at the JDBC Gateway I noticed that at the Server Level it was down. However the page keeps timing out when ever I attempt to make any changes or start it, it will not respond.

I thought I had found the Cache command to start it but it will not start. Is the following steps correct?

As we all know, Caché is a great database that accomplishes lots of tasks within itself. However, what do you do when you need to access an external database? One way is to use the Caché SQL Gateway via JDBC. In this article, my goal is to answer the following questions to help you familiarize yourself with the technology and debug some common problems.

Outline

• What are the connection parameters you need to connect to a remote database?
• What is the JDBC Gateway vs the Java Gateway Service in Ensemble?
• What tools and methods are available to debug issues?
• What are common types of problems and

Is it possible to access (read, write) to an external Oracle database via Cache SQL Gateway using JDBC in Cache Object Script?  I am currently using ODBC successfully but wanted to see if JDBC was an option too.  If it is possible, does anyone have a basic Object Script example(s) that I can review?

Thanks!

Hi ,

     When I use jdbc driver to query the column info ,the "REMARKS" field always show the same as the "COLUMN_NAME" field.

When I use the sql "select * from INFORMATION_SCHEMA.columns a where a.table_name='some table name ' " to query columns info,there has a "DESCRIPTION" field ,the value is some comment for the current field.

So is there anyway to return the description to the jdbc  remarks field? And is there anyway to update the desciption or remarks field? Or is there some other way that I don't know to manage column comment info?

Hi team,

I'll start with an apology as I am trying to wrap my head around the architecture of how InterSystems IRIS database management works. I am attempting to connect to the platform remotely through say a JDBC or ODBC connection in order to run queries, searches (through SQL statements) on my laptop and was trying to understand whether this would be possible? It is possible to setup an inbound client connection and wanted to better understand the architecture of how the database association works for IRIS database management. Does it use it's own internal SQL database or are we able to connect to our own database and which databases are certified to run against the platform?

Hi,

Hello,

I work on deploying IRIS using Kubernetes operator and Red Hat OpenShift. I encouraged another team working on Java application to consider using IRIS as database. My team deployed IRIS cluster using two mirrored data pods for the other team. The other team asked me for the connection information.

To learn how to use Java with IRIS, I attempted to deploy two apps from Open Exchange:

Here I got errors like this:

package com.intersystems.jdbc does not  exist

Hello everyone!

I am writing a SQL CALL (using JDBC) to a stored procedure that outputs a structured object (Oracle Object).

However, the adapter method is not accepting the corresponding JDBC Data Type STRUCT for the output parameter, returning the following error:

ERRO #5023: Erro no Gateway Remoto: JDBC Gateway SP execute(0) error 0: Remote JDBC error: ORA-06550: line 1, column 7:
PLS-00306: wrong number or types of arguments in call to 'AGUARDAR_EVENTO'

We are planning to build a REST API with the Java Quarkus Framework.

• There'll be a connection pool;
• The DataSource instance will be automatically injected from the connection pool;
• We will use JDBI to do SQL instructions and this will give us automatic Connection and Statement management;

This Caché instance already have COS applications running and consuming connections and licenses.

After doing this, we will migrate to IRIS.

Is there any pitfalls that we must be aware before taking this approach?

If you want to see some code the PoC can be found here.

Thanks.

Consider a Natural Key with an Identity (Serial) field.

I cannot seem to acquire the generated value after persisting my entity. That is, the returned entity by Spring Data's "save" does not have the generated value.

The value is generated by the database, and I can query it after repository.save(entity).

I have done some testing and created a Github repo with it...

5 years ago, on December 19, 2013, the ESA launched an orbital telescope called Gaia. Learn more about the Gaia mission on the official website of the European Space Agency or in the article by Vitaly Egorov (Billion pixels for a billion stars).

However, few people know what technology the agency chose for storing and processing the data collected by Gaia. Two years before the launch, in 2011, the developers were considering a number of candidates (see “Astrostatistics and Data Mining” by Luis Manuel Sarro, Laurent Eyer, William O’Mullane, Joris De Ridder, pp. 111-112):

• IBM DB2,
• PostgreSQL,
• Apache Hadoop,
• Apache Cassandra and
• InterSystems Caché (to be more precise, the Caché eXTreme Event Persistence technology).

Comparing the technologies side-by-side produced the following results (source):

The first four will probably sound familiar even to schoolchildren. But what is Caché XEP?
