GraphQL is a standard for declaring data structures and methods of data access that serves as a middleware layer between the client and the server. If you’ve never heard about GraphQL, here is a couple of useful online resources: here, here and here.

In this article, I will tell you how you can use GraphQL in your projects based on InterSystems technologies.

Hi,

I was wondering if there were any guides, similar to the ones for an upgrade, that walkthrough at a high/medium level the process for migrating an Ensemble Instance.

I am presuming that the general flow would be to install a fresh instance in the target environment, and migrate items over.. but any specific order? gotchas? things to avoid? Some things that should/shouldn't be im/exported (ie, must be manually migrated) ?

Timeout for $zf

In one of the projects, when we have ECP with 10 ECP application servers, from time to time we faced the issue when our journals fail to purge, due to open transactions. While we have about 100-150 GB journal files per day, it quite quickly became a big issue, and with mirroring a very big issue. Mostly we just rebooted our ECP Data server, so it searches rollbacks any transactions, but such process is too long, may steal a few hours. I did not find any way, how to get the list of the open transactions from one place from ECP Data Server. We just migrated our Data server to 2018.1.

Hi

We are trying to use Ensemble as a Router for DICOM Worklist. So when a DICOM Client sends a request (ECHO Or C-FIND), We want Ensemble to carry such request to Epic EMR. When Epic EMR responds with a Response, We need to be able to forward that response back to DICOM Client. I wanted to see If anyone has a working example of this scenario.

Examples we have in DEMO namespace are not entirely falling into this scenario.

Hello I am looking to take a message that is coming from a radiology service, depict whether there were abnormal findings. Then create a message that can be sent to a printer and mailed for patient follow up. Has anyone done anything with printing a created message from Ensemble before? I have created dynamic emails, but never printed anything.

Thanks!

Joe

SQLCODE Error -400

I have a code block in a BPL. I have the below SQL and code. All variables have been declared and set. When I run the SQL, if there are no values returned, I get 100 for the value of SQLCODE when I perform the FETCH, which is correct. If values are returned, I get a -400 error when I perform the first FETCH. I've investigated, but cannot find the reason for a -400 error. Hoping someone out here understands this and knows what's wrong.

Created a record map to read a flat-file of lab results.

Have multiple lines that represent result components for a given order per pt MRN.

Grouping these records together based upon the order number in a custom service to create a single XML message.

Within the XML message, there are some fields that occur once and some that occur one or more times.

Within the record map, the fields/properties that occur once are configured as "As %String. The fields/properties that occur more than once are configured as "As List of %String.

Hello All,

I am able to transmit a small batch of billing files: B/W 5 and 20 without issue-
Put stream 11@%IO.LibraryStream to /SFTP/unmhsmcsa/OUT/TEST_021920201426.tst

But when the size of the batch increases to over 20 the operation hangs and I receive the error below: The file is created in the SFTP server with 0 data.

Class Queries

Class Queries in InterSystems IRIS (and Cache, Ensemble, HealthShare) is a useful tool that separates SQL queries from Object Script code. Basically, it works like this: suppose that you want to use the same SQL query with different arguments in several different places.In this case you can avoid code duplication by declaring the query body as a class query and then calling this query by name.

I understand RecordMaps can be used to send delimited files through a production without custom coding. The data segments are delimited by tilde character followed by $Char(10) in Linux/Unix. When I test the same IO data in Windows, I have $Char(13) and $Char(10) instead of just $Char(10). I like to use just tilde character for record delimiter and ignore $Char(13) and $Char(10) between the tilde and the leading data of the next segment / record. Is this good idea or not if someone wants to generate classes will it override code?

I'm not sure what the purpose of this is, but the Management Console causes the browser to refresh periodically. If you're in a form or an editor such as the DTL or Routing Rule editors, you may lose work unless you save frequently. This did not occur in Caché 2018 and earlier releases.

I've had a couple of incidents where I've created a number of rules in the DTL editor, answered the phone or stepped away for a few minutes, then come back to find any work since the last save erased.

I've noticed this in both 2019 and 2020 releases of IRIS.

Heads up!
