Hello Fellow Caché Developers,

The purpose of this post is to ask for everyone's thoughts and input around the use of transient, SQLCalculated/Computed properties within persistent classes.

This approach allows for extra data values needed in SQL queries to be available without having to join to other tables.

Very simple/basic example to illustrate the topic:

Let's say I have a persistent class named ICDAutoCodeDefn to hold ICD Auto-Coding definitions, such as:

Is there a way to use a HL7 field value as part of the File Naming in the Business Operation FileOperation class. I know we can do this in a custom class, but I was wondering if it could be done the default FileOperation class?

Example:

MSH-4 contains the value 12345

We would like to name the file 12345_YYYYMMDDHHMMSS.HL7

MSH.4 value here_%Y%m%d%H%M%S.HL7

It may not be possible, but I just want to see if anyone has any information

Thanks,

Kevin Brown

Cache Compile Problem

Hi Guys,

We experiencing a strange problem with one of the clients on Cache 2008, for time to time they can't run any of their Crystal reports and each time we had re-compile the classes used in the affected report to get it running, then it happens again for the same reports.

This is not an issue in ObjectScript, due to its typeless nature. But it's essential for external programming languages that care a bit more about types of variables.

And in any case, it's still reproducible in ObjectScript. I have table

CREATE TABLE some_table (
        id INTEGER NOT NULL, 
        x INTEGER, 
        y INTEGER, 
        z VARCHAR(50), 
        PRIMARY KEY (id)
)

And data

INSERT INTO some_table (id, x, y, z) VALUES (1, 1, 2, 'z1');
INSERT INTO some_table (id, x, y, z) VALUES (2, 2, 3, 'z2');
INSERT INTO some_table (id, x, y, z) VALUES (3, 3, 4, 'z3');
INSERT INTO some_table (id, x, y, z) VALUES (4, 4, 5, 'z4');

Available space in a DB

When we run data purges in a namespace, the size and space of the DB does not change. I assume like Oracle it leaves white space that is usable by cache, but is there a way to see how much of this space is available? Today I increased the size of the disk available to the system as we were reaching critical low disk space, however, with the purges, we should have several hundred GB of available space inside the database to use. And is it safe to allow the system to run out of available disk space, as long as there is enough free space in the DB for writing data?

InterSystems has identified an issue with product distributions containing Certificate Authority certificates that expire at the end of 2020. This issue does not affect system operation or system security in any way, although it does generate alerts about expiring certificates in the cconsole.log or messages.log files.

Hello!

Intersystems is a fascinating yet niche marketed.
We are using it, but we struggle to find good developers to join us to work on Caché or Ensemble products.

Who is interested into joining us? the job will be in Geneva, Switzerland!

For more information, please drop me an email to: erika.stegagnini@ch.randstad.com or call me directly +41 58 2015408.

Thanks!
Erika

%UnitTest Code Coverage

Hi,

When we write unit test cases for cache object script code using %UnitTest.TestCase, what is the best way to write code to identify code coverage?

So, let say my unit test case hit all 10 lines of code of a method for a given class. So, unit test coverage should be 100% for that. But, using line-by-line coverage [(%Monitor.System.LineByLine] getting wrong percentage, because it also includes code comment/documentation as part of code. So, practically we can not ever achieve 100% of code coverage by using this API.

Using ECP across IRIS and Caché

Migration from Caché to IRIS can be quite a challenge if your code is grown over many years
and probably not so clean structured as you may like it. So you face the need to check your
migrated code against some reference data. A few samples might not be a problem,
but some hundred GB of data for testing might be.

A possible step could be to have your fresh code in IRIS but leave your huge datastore on Caché and connect both environments over ECP. I have created a demo project that gives you the opportunity to try this based on 2 Docker images with IRIS and with Caché connected over ECP.

Artificial intelligence has solved countless human challenges – and medical coding might be next.
As organizations prepare for ICD-11, medical coding is about to become more complicated. Healthcare organizations in the United States already manage 140,000+ codes in ICD-10. With ICD-11, that number will rise.
Some propose artificial intelligence as a solution. AI could aid computer-based medical coding systems, identifying errors, enhancing patient care, and optimizing revenue cycles, among other benefits.

We have a requirement to write to an AWS S3 bucket from Cache.

We haven't upgrade to IRIS yet, but are looking at doing so in the future. This requirement cannot wait for the upgrade to happen, unfortunately.

Will appreciate if any one can share any example code, that enables cache to write to an AWS S3 bucket?

I have an interface that does not send me specific ID's, so I am scanning the AIL3.2 (Text) field for certain characters. The Routing rule is getting pretty big with all the OR statements. Is there a way that I can define what I am searching for in the data lookup table, and not have to scan the whole field that it does by default? Is there a way that I can simplify this?
