Hi

I get always the following error when I query our FHIR repository with a specific TAG

/csp/healthshare/fhirserver/fhir/Encounter?_tag=

ERROR #5002: Cache error: <INVALID OREF>zSearch+86 ^HS.FHIR.Repository.Operations.1

I've deleted rows from cache database. On the table HS_FHIR_Repository_Resource.Encounter as we had duplicate records...

Any help would be great

Kind Regards,

Joao Palma

Hi everyone!

We have many severs (DEV, QA and LIVE) besides many other slave servers (about 133) that are running Caché instances. Before writing this utility myself, I would like to know if anyone has done it before. We need to change the SuperUser password and do other credential setups like this on all of these servers and we don't want to do it one by one.

A few customers have seen this happen, so I thought it would be worth mentioning here on the Developer Community. This could affect users running versions between 2014.1.3 and latest who install or upgrade Wireshark. There is a bug in the Visual C++ 2013 redistributable shipped with the current Wireshark 2.2.1.

This is from Microsoft’s bug report https://support.microsoft.com/en-us/kb/3138367 :

I would like to start a discussion regarding Caché Objects and Caché SQL.

It is my understanding that the creators of Caché Objects see Caché SQL as the reporting arm of Objects and as such SQL is essential to Caché Objects.

I once met a Caché Objects programmer who was writing code to $Order through the Globals because that person thought that Caché SQL was too slow and inefficient. I attempted to convince the person otherwise.

So, what say you? Is SQL essential to Caché Objects?

This is a translation of the following article. Thanks [@Evgeny Shvarov] for the help in translation.

This post is also available on Habrahabrru.

The post was inspired by this Habrahabr article: Interval-associative arrayru→en.

Since the original implementation relies on Python slices, the Caché public may find the following article useful: Everything you wanted to know about slicesru→en.

Note: Please note that the exact functional equivalent of Python slices has never been implemented in Caché, since this functionality has never been required.

And, of course, some theory: Interval treeru→en.

All right, let’s cut to the chase and take a look at some examples.

Hello,

I have been struggling and could use some help as I think I'm burnt. I am trying to change a Textual 2.5.1 OBX;5 with multiple iterations to a simple non-iterating outbound result. I have played around with $piece but can't seem to get it to work. The outcome I would like is for OBX;5 to look like this: |Positive| and currently it looks like this: |Positive~_~_~_~_~|. Any suggestions would be appreciated.

June 26, 2017 – Alert: Data Corruption with Mixed Endian Mirror Shadowing

InterSystems has corrected a defect that may result in corruption of Unicode data on a shadow system whose source is an async mirror member.

This defect affects all currently released Caché, Ensemble, and HealthShare distributions beginning with version 2012.2.0. All platforms and operating systems are affected.

Hello community,

I would like to know answer to the question: What would be an optimal way to connect an Ensemble and a pure Caché server? Optimally in such a way for the Caché system to be able to fire Ensemble processes and the Ensemble server to call Caché server functions.

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

Question
· Jun 22, 2017
Hash values of columns

I try to find a function, which generates hash values of columns. In MS SQL Server I can use

select hashbytes('sha2_256', my_column) ...

to create hash values of my_column. Is it possible to use such things in Caché?

Thank you
André
