Does anyone have any experience with getting, unfortunately, an older version of Cache to authenticate via SMTP to send email? I have verified that the settings are set up properly on the mailbox as I have successfully sent an email from a LAMP server, which comes from the same IP address.

If you have any thoughts, I would greatly appreciate it.

This is the error I receive

ERROR #6034: SMTP server connection failed during MAIL FROM command: <READ>zSend+105^%Net.SMTP.1.

JSON to HL7

I have a project to convert a JSON message with two patient identifiers into an HL7 ADT^A31. Is there any documentation or training that you would think is appropriate?

Currently using Ensemble 2014.1.5 on AIX

I have a NewBie Question.

I have been playing around with "Basic CLass Queries."

I have defined a very simple "Basic Class Query." (see below)

However, I cannot find in the I/S documentation how to execute this query.

Any help is appreciated.

EnsLib.HL7.Message.cls provides many API methods for manipulating an HL7 message. RemoveSegmentAt(), for example, can be used to remove a segment by path or index, but only one segment at a time. There may be times that you'll need to remove all segments within a group or even many groups of segments from the HL7 message. Surely you can iterate through each segment in each group and remove them one by one, but there's a much easier way.

With just one command, like below, you can remove all OBX segments in an ORU_R01 message (msg):

One of the benefits of Atelier is easy integration with source code management tools. Some Eclipse installations include the EGit plugin, or you can install it from the Eclipse marketplace. EGIt makes integration with Git and GitHub easy. Here are the steps I used to connect Atelier to a GitHub repository:

Macros in the InterSystems Caché

In this article I would like to tell you about macros in InterSystems Caché. A macro is a symbolic name that is replaced with a set of instructions during compilation. A macro can “unfold” in various instruction sets each time it is called, depending on the parameters passed to it and activated scenarios. This can be both static code and the result of ObjectScript execution. Let's take a look at how you can use them in your application.

TLS v1.2 support in Caché

Question:

What version of Caché supports TLS v1.2?

Answer:

Caché 2015.2 announced support for TLS v1.1 and v1.2. In this version, the SSL/TLS configuration page provides checkboxes for TLS v1.1 and v1.2, which allows the versions to be configured individually. This allows sites to, for example, require TLS v1.2 only.

Additionally, some earlier versions of Caché provide undocumented support for TLS v1.1 and v1.2, specifically Caché 2014.1.3 and above and 2015.1, on Windows, Linux and Unix.

Get columns dynamically?

In MSSQL I think you can do something like this:

select *
from HS_IHE_ATNA_Repository.COLUMNS
where TABLE_NAME=&#39;Aggregation&#39;

How can I do this in Cache SQL?

[%msg: < Table 'HS_IHE_ATNA_REPOSITORY.COLUMNS' not found>]

Let's say I open a stream/file.

If it's not in UTF8 i need to call $ZCVT, and if it's already in UTF8, then I don't need to call $ZCVT.

Is there any way to determine character encoding for input stream/file?

Simple Cache systemd Unit

Hello

I have noticed that Cache (2016.1 at the time of writing) doesn't come with a systemd startup script for RHEL7.

Here is a small example script I have built.

[Unit]
Description=Intersystems Cache

[Service]
Type=forking
ExecStart=/bin/bash -c '/usr/cachesys/cstart 2>&1 | logger -t cache_start'
ExecStop=/bin/bash -c '/usr/cachesys/cstop quietly 2>&1 | logger -t cache_stop'
RemainAfterExit=yes

[Install]
WantedBy=multi-user.target

The file should be placed as /usr/lib/systemd/system/cache.service
