Documentation

At least three different ways to process errors (status codes, exceptions, SQLCODE etc is given in ObjectScript. Most systems have status, but for a range of reasons exceptions are more convenient to manage. You spend some time translating between the various techniques dealing with legacy code. For reference, I use several of these excerpts. It is hoped that they will also support others.

How to check the size of your data

InterSystems FAQ rubric

Data for InterSystems products (table row data, object instance data) is stored in global variables.
The data size of each global can be obtained by clicking the properties of the global you want to view from the Management Portal > System > Configuration > Local Database > Globals page, and then clicking the Calculate Size button on the Global Attributes page that appears.
To display the data sizes of globals in a namespace, you can call ^%GSIZE utility on the terminal.

Diagnosing the cause of <PROTECT> errors

If your application is raising <PROTECT> errors and you're finding it hard to work out why, here's a way to get additional information.

First, if auditing is not already enabled, turn it on:

Then use "Configure System Events" (highlighted above) and locate the event named %System/%Security/Protect. In the screenshot below I used the Filter field to do this (type "protect" - highlighted below - and press TAB):

File Passthrough Feeder

IRIS Interoperability Productions formerly known as Ensemble are fun to work with. Yes, I really think my work is fun. I have seen File Passthrough Services and File Passthrough Operations come in handy. At one point we placed test messages in files, then we utilized a File Passthrough Service with Inbound File Adapter to send the contents of the file as a Stream to a File Passthrough Operation with Outbound TCP Adapter.

How to find your imported XSD file

Have you ever imported an XML schema from an XSD file? You might want to look at the original file again sometime later, but forgot where you put it.

Do not worry, that information is being kept as part of the import process.

The whole imported XSD schema is being kept in the ^EnsEDI.XML.Schema global. That global holds all the imported XSDs in your namespace. The first subscript is the name of the schema that you see in the portal.

To resolve the error <PROTECT>, remove the read-only attribute of the system-wide library database (IRISLIB for InterSystems IRIS, CACHELIB for Caché/Ensemble/HealthShare (Caché-based))

Once you have finished importing the routine, remember to change it back to read-only.

[Version 2013.1 and above]
[Management Portal] > [System Administration] > [Configuration] > [System Configuration] > [Local Database] Uncheck "Mount read-only" from the database name link.

Installation

To install isc-dev , you just need to download and import the file isc-dev.xml from last release.
Some ways to import isc-dev .xml file:

  • Go to Management Portal -> System Explorer -> Classes -> Import and select the XML file.
  • Drag the file over Studio.
  • Terminal command:
NS>do $system.OBJ.Load("yourpath/isc-dev.xml","ck")

NS>zpm
zpm: NS>install isc-dev

How to enable this feature:

  • After importing the class in the target namespace, run the following method to set up the working directory:
NS>do ##class(dev.code).workdir("/path/to/your/working/directory/src/")
  • Go to Management Portal -> System Administration -> Configuration -> Additional Settings -> Source Control.
  • Select the target namespace and set the dev.FileManExtension class as the main one and save it.
  • Try to create a new class in the studio and save/compile it
  • Enjoy!

Hey everyone!

I recently learnt something new while working with WRC on an issue, and I wanted to share with everyone on the off chance it could help someone else.

Scenario:

Files are being inexplicably written to a folder on your server and, due to the number of files in the folder and general system throughput, it is not possible to work through the files to track down the source.

IRIS/Ensemble as an ETL

IRIS and Ensemble are designed to act as an ESB/EAI. This mean they are build to process lots of small messages.

But some times, in real life we have to use them as ETL. The down side is not that they can't do so, but it can take a long time to process millions of row at once.

To improve performance, I have created a new SQLOutboundAdaptor who only works with JDBC.

BatchSqlOutboundAdapter

Extend EnsLib.SQL.OutboundAdapter to add batch batch and fetch support on JDBC connection.

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):

Diagnosing Framing Errors

Framing refers to the characters that mark the start and end of an HL7 message (or other types of framed messages). Most HL7 services and operations have a Framing setting that allows the user to define this framing. The most common choices are available as defaults, but with the AsciiMM/NN setting, components can be configured to recognize any framing characters.

Portal tip: The inconspicuous Menu button

Amongst the large fonts and chunky icons of Portal's pages, the Menu button in the top left corner is easily overlooked:

When clicked, it often produces the following menu:

When I remember it's there, I find the "View Console Log" option particularly handy.

I wrote "often" above because I've also noticed that the Menu contents change when I'm on a page within the Ensemble section of Portal:

If you work with interoperability productions of InterSystems IRIS or Ensemble, no doubt you are familiar with the Message Viewer page. The page supports filtering messages according to filter criteria you enter in the Basic and/or Extended Criteria sections. Extended Criteria conditions are specified as property-operator-value triples. Once you click Search button, such triples become WHERE clause conditions of a generated SQL query executed against message header/body tables.

It can be retrieved using the schema INFORMATION_SCHEMA.

INFORMATION_SCHEMA is a system schema and is not displayed by default in the SQL menu of the Management Portal.

The method to display it is as follows.

  1. Open Management Portal → System Explorer → SQL menu.
  2. Check "System" on the left of the schema drop-down.
  3. Select INFORMATION_SCHEMA from the schema dropdown.

If you do not specify the option to remove the mirror attribute of the mirror database when deleting the mirror configuration, the database cannot be restored to a normal state and will be mounted read-only the next time it is mounted. To restore the database to a read-write state, you must remove the mirror attribute using the system routine ^MIRROR.

The procedure is as follows (execute in the %SYS namespace):

One of the topics that comes up often when managing Ensemble productions is disk space:

The database (the CACHE.DAT file) grows in a rate that was unexpected; or the Journal files build up at a fast pace; or the database grows continuously though the system has a scheduled purge of the Ensemble runtime data.

It would have been better if these kind of phenomena would have been observed and accounted for yet at the development and testing stage rather than on a live system.

For this purpose I created a basic framework that could aid in this task.

I'm pleased to see this in the documentation of the just-published 2017.1 Field Test of Ensemble:

"In certain circumstances, it is useful to create namespaces that are not enabled for Ensemble. In this release you can do this by clearing the Make this an Ensemble namespace checkbox when creating a new namespace. "

Hi ObjectScript developers!

How to Protect Your Belongings from Pests While Moving - Delicate ...

InterSystems ObjectScript is perhaps the best language on the planet to deal with globals - and it is an interpretable language.

Yes, it has a compiler. But even the compiler can compile some lines in ObjectScript which will then fire as bugs during the runtime.

There are some technics on how to avoid that such as unit testing, coding guidelines and your coding experience, of course ;)

Here I want to present to you the yet another approach to how you can reduce the number of errors in your ObjectScript runtime and enforce coding guidelines - it's an ObjectScript Quality tool developed by Lite Solutions, InterSystems solution partner.

See the details below.
