Variables in Global Name

I have a number of globals I want to loop through depending on a passed in string...

^A("SYSTEM")

^B("SYSTEM")

^C("SYSTEM")

^D("SYSTEM")

^E("SYSTEM")

I am passing in a string of "A:C:D"

Piecing that to pull out A,C,D, then want to use that to pull out A,C,D from above, but having problems setting the name of the global to be the name of the variable I have pulled out of the string

How do I set this?

I have tried ^varname("SYSTEM")

Fast JSON formatting (IRIS)

t's also an example for a customized command extension (ZZJSON) in IRIS

IRIS has a nice %JSON.Formatter class.
But for debugging it is not really handy.
see:

ZWRITE js1  
js1="{""Name"":""Cunningham,John C."",""SSN"":""294-11-9150"",""DOB"":""1933-01-08"",""Home"":{""Street"":""4249 Ash Street"",""City"":""Tampa"",""State"":""MD"",""Zip"":""30176""},""FavoriteColors"":\[""White"",""Red"",""Green""]}"   

so you proceed for the most simple case

Hi guys, I'm helping one of our customer to use unattended install to standardize their deployment. I'm using Unattended Installation and Installation Manifest.

Although I can use the combination to install HealthConnect and then create namespaces and DBs as they need, there are still several tasks that I did not find the solution yet. As following:

1. Configure mirrors

2. Set the directory to store journals

I have an Ensemble installation with an FTP business operation which I would like to connect to a server over SSL in explicit mode (see also: https://www.rebex.net/kb/tls-ssl-explicit-implicit/default.aspx). I keep running into timeouts while attempting to do this via Ensemble. Does Ensemble actually support SSL in explicit mode??? Because I can't seem to find any setting where to switch it on.

I've asked a lot of questions leading up to this, so I wanted to share some of my progress.

The blue line represents the number of messages processed. The background color represents the average response time. You can see ticks for each hour (and bigger ticks for each day). Hovering over any point in the graph will show you the numbers for that period in time.

This is super useful for "at a glance" performance monitoring as well as establishing patterns in our utilization.

I have table

CREATE TABLE nodes (
        name VARCHAR(50) NOT NULL, 
        parent VARCHAR(50), 
        PRIMARY KEY (name), 
        FOREIGN KEY(parent) REFERENCES nodes (name) ON UPDATE cascade
);

I put some data

INSERT INTO nodes (name, parent) VALUES ('n1', NULL);
INSERT INTO nodes (name, parent) VALUES ('n11', 'n1');
INSERT INTO nodes (name, parent) VALUES ('n12', 'n1');
INSERT INTO nodes (name, parent) VALUES ('n13', 'n1');

Let's delete all

DELETE FROM nodes;

Nope, no way.

SQL Error [124] [S1000]: [SQLCODE: <-124>:<FOREIGN KEY constraint failed referential check upon DELETE of row in referenced table>]
[Location: <ServerLoop>]
[%msg: <At least 1 Row exists in table 'SQLUser.nodes' which references key 'NODESPKey2' - Foreign Key Constraint 'NODESFKey3', Field(s) 'parent' failed on referential action of NO ACTION>]

We have the following code, but recently had a few issues with messages sent to downstream systems being rejected.
After investigating, seems that the message being sent is being truncated, the RawContent that we are pulling from Ens.EnsLib_HL7.Message only has the first 10k of the message

We are storing message body IDs in a table, then when we receive later messages, we look up the corresponding record in the table,
extract the message and alter some fields from the saved message based on the received message and send onto downstream systems

Hi folks!

I'm curious if it is possible to change the class method to another class?

I call a method of a system class to generate another class. But there is a bug/feature in a library class, so I need to tweak a bit the generated method, e.g. add additional parameter and change the line to "if" the parameter.

I hope to do this programmatically after class generation and change the code in a way I like.

What are the options?

Debugging Business Operations

Often we need to debug a Business Operation. Tracing and logging work but sometimes you want to work with a BO as with your local terminal session.

Here's how you can do that on any operating system.

Windows has a great tool for debugging Business Operations - Foreground mode. In that mode Windows launches a local terminal with operation job.

EnableConfigItem() scripting

We have scripted a process where we can run EnableConfigItem from the cron in AIX so we can run multiple scripts at a time vs the scheduler in Ensemble that is single threaded. For the most part this works fine, until that service/operation has an error on it then it seems that everything else that is called after that instance halts.

Is there something that is stopping EnsConfigItem() from running once something has error'd?

Can something be forced like it does if we try to enable/disable in the gui and it times out?

this is the single command line we are calling

It is often necessary to sort the results of a query on a string field containing a combination of alphabetic and numeric characters. In cases like this the default string collation may not always return the data in the expected sequence.

An example of this may be where a select from Samples.Person should order the results by the street address, but firstly ordered by the street number part as numeric, and then by the street name.

The default query will return the results as follows:

VIP in GCP

If you're running IRIS in a mirrored configuration for HA in GCP, the question of providing a Mirror VIP (Virtual IP) becomes relevant. Virtual IP offers a way for downstream systems to interact with IRIS using one IP address. Even when a failover happens, downstream systems can reconnect to the same IP address and continue working.

The main issue, when deploying to GCP, is that an IRIS VIP has a requirement of IRIS being essentially a network admin, per the docs.

To get HA, IRIS mirror members must be deployed to different availability zones in one subnet (which is possible in GCP as subnets always span the entire region). One of the solutions might be load balancers, but they, of course, cost extra, and you need to administrate them.

In this article, I would like to provide a way to configure a Mirror VIP without using Load Balancers suggested in most other GCP reference architectures.

You may have already heard that, starting with IRIS and HealthShare HealthConnect 2023.2 versions, the internal Apache Server will be removed from the default installation, so it will be necessary to have an external application server such as Apache Server or NGINX.


In this article I am going to proceed to install a HealthShare HealthConnect 2023.1 so that it works with a pre-installed Apache Server. For this I will use a virtual machine on which I have installed an Ubuntu 22.04.
