Standardizing Error Logging

I have been tasked with creating a class that will handle error logging in a consistent manor for an application I am working on. The need is to have all variables in the calling method logged along with some other information.

The example given was zwrite which is exactly what I need, however, I somehow need to capture the output of ZW and put it into a database table. Any easy way to capture this data? I was able to dump ZW to a file, but that is not ideal.

Any help is appreciated!

As many of you, our partners, are more widely using modern UI frameworks to create client front-end, you may have encountered a question, "So how do I secure my data when I just finished developing all new fancy browser based client experience?"

The answer is easy. Use a standard, proven OAuth2 and OpenID!

"OK, but how can I do it? I have never done it before."

No problem, just have a look here, if your client is Angular (not AngularJS) based, there is a demo project available for you to review and get inspired!

Making the most of $Query

I ran into an interesting ObjectScript use case today with a general solution that I wanted to share.

Use case:

I have a JSON array (specifically, in my case, an array of issues from Jira) that I want to aggregate over a few fields - say, category, priority, and issue type. I then want to flatten the aggregates into a simple list with the total for each of the groups. Of course, for the aggregation, it makes sense to use a local array in the form:

agg(category, priority, type) = total

Such that for each record in the input array I can just:

Dynamic SQL to Dynamic Object

Hello community! I have to work with queries using all kinds of methods like embedded sql and class queries. But my favorite is dynamic sql, simply because of how easy it is to manipulate them at runtime. The downside to writing a lot of these is the maintenance of the code and interacting with the output in a meaningful way.

Hi all,

In the days when I was still using studio, the indentation character of choice was tab, due to misalignment of code when using non-monospaced fonts.

In VSCode when I create new class files, this defaults to 4 spaces. Where and how do I set the default indentation for ObjectScript class files?

Also, with python it should be spaces. So what is recommended when doing python script inside objectscript classes?

Thank you.

Suppose I have an image and need to convert that image into a PDF for inclusion in an HL7.

I know that Zen Reports can display an image in a PDF but I do not want to view the image in a web page. I just need to convert the image to PDF in a Process and then include that PDF in an HL7. The workflow would be like this:

Get image -> Convert image into PDF -> Include PDF in HL7 OBX.

I know how to do the last part to include PDF in HL7 OBX. Just need ideas on the first part.

Whenever the Windows SNMP Service restarts, the snmpdbg log says the following.

13:08:59 :Attempting initial TCP connection(s) with 1 Cache instances ...
13:08:59 :Get connection with ENSEMBLE on port 1972
13:08:59 :Connection refused on port 1972, check if Cache instance ENSEMBLE is started.
13:08:59 :Cache iscsnmp.dll initialized for 1 configs

Ensemble and all productions are running. I've set up Caché SNMP agent on many other servers in our company and those are working fine. However this one server won't budge.

Today my customer ask me a question about how to write the MDX with a summary row however this row with different aggregate functions for each column.

We know in DeepSee analyzer has pivot table option "Summary", user can select sum, avg ... aggregate functions to get the summary row/column. However we can not specify different aggregate function for each measure column.

Here show the example to use All level and IIF function achieve that. see the example (Holefood cube in Sample namespace) below

Suppose you have a persistent class with data and you want to have a simple Angular UI for it to view the data and make CRUD operations.

Recently @Alberto Fuentes described how to build Angular UI for your InterSystems IRIS application using RESTForms2.

In this article, I want to tell you how you can get a simple Angular UI to CRUD and view your InterSystems IRIS class data automatically in less than 5 minutes.

Let's go!

Hi everyone

How can I connect using the Terminal to a remote server?

I changed the server indication on the Healthshare icon on the Windows toolbar.

The management portal works but not the Terminal. When I open the terminal it displays only some information about the server ("SSH-2.0-OpenSSH_7.2p2 Ubuntu-4ubuntu2.2"), but it doesn't give the possibility to log in.

Do you have any suggestions how I could fix it?

Thanks a lot and best regards

Milena
