When we have to predict the value of a categorical (or discrete) outcome we use logistic regression. I believe we use linear regression to also predict the value of an outcome given the input values.

Then, what is the difference between the two methodologies?

Hi

Just want to know the difference between IRIS and IRIS for Health?

Thanks
 

Here are a few examples of conversions and operations you might need, along with links to documentation where you can learn more.

At the time I wrote this, Eastern Daylight Time was in effect for my Caché system.

How Caché keeps the time and date

Caché has a simple time format, with a longer range of recognized dates compared to some other technologies.

The current time is maintained in a special variable $HOROLOG ($H):

USER>WRITE $H64146,54027USER>

The first integer is the count of days since December 31, 1840. The second integer is the count of seconds since midnight of the current day.

tahnks for answering

The release of InterSystems IRIS 2021.1 introduces Adaptive Analytics. To get started with a familiar InterSystems IRIS BI sample cube, we have created a HoleFoods Sample Application for Adaptive Analytics. This Sample Application is available on Open Exchange. There is also a learning services course available to learn more about Adaptive Analytics.

I'm working with a REST API that will sometimes rate limit our requests by returning an HTTP 429 Too Many Requests status code. Is there a good way in a business operation to handle this by throttling our requests until we get a success response? My initial thoughts are:

• Reduce the pool size on the business operation to 1 so all requests are first in, first out.
• If the API returns a 429 response, set %rate = $get(%rate,1)*2, then hang %rate, then send the request to the back of the queue.
• If the API returns a success response, kill %rate

We’re looking for Python developers to participate in our Embedded Python Early Access Program!  If you (or someone you know) are a Python developer and are interested, please contact us via the email address below.

InterSystems is bringing the power and simplicity of Python to IRIS.  We’re hard at work integrating Python directly into the IRIS kernel, making it a full peer to ObjectScript.

• Use any of thousands of pre-built Python libraries
• Easy access to IRIS from Python, and Python from ObjectScript
• Mixed ObjectScript and Python classes

I have created a custom role in IRIS for users to provide limited view-only access for querying tables in the HSANALYTICS namespace. WinSQL has been installed on a Windows server (WinSQL Lite version 14.0.244.784) and an ODBC connection entry has been created in WinSQL for the users to log in and run SQL queries. The custom role provides the roles/resources included in the attached file. The WinSQL System DSN entry defined is:

Health Insight UAT HSANALYTICS    64-bit    InterSystems ODBC35

The ODBC35 driver is defined as:

InterSystems ODBC35    2018.01.00.184    CACHEODBC3564.DLL    9/19/2018

Hi developers!

Hi,

I have a DR member and in this cache server the database "cachetemp" start to getting bigger without any reason (50GB that was all the free disk space we have)

In the members of the mirrors the cachetemp its ok and the size is 31MB.

I restarted the server because I read that the cachetemp database purge when restarting, but didnt happend.

Any recommendation to clean this database? can I just deleate the CACHE.DAT from this database?

Thanks!!!

Hi

While configuring FHIR Server I could not find "Health > FHIR Configuration > Server Configuration" option. I am using InterSystems IRIS community edition on my local PC.

Thanks

Hi everyone, 

I am talking from Brazil and we have one very important customer that requested our support to find a consultant, deeply specialized in Cache that could work with us attending this customer. It has a tons of data and its core application is based on Cache.

If you are interested send me an email with the subject title - Cache consultant opportunity - and we will make contact with you. The main request is how strong are your skills in cache and it would be considered a differentiator if you are a portuguese speaker.

Regards - Helberth Cavalcante.

Hi

I have had customers who would rather use a backup application rather than using IRIS Backups. In my experience, I have tried a number of free backup tools and I have paid for at least two "very good Backup Tools" and all of them have failed to create usable backups especially if my Ensemble/IRIS Instances are still running and even if Ensemble/IRIS have been shut down I have found that the backups created by these tools have around an 80% chance of being able to restore a system (let's assume that I am not trying to backup core Windows elements like the Registry and Windows system files). 

Error:$ZERROR: <ZSG>%Save+5^GL.Account.1

Does anyone know what this error means?

Hi colleagues!

Is there a way to export globals in XML if I have the access to Management Portal or any other web app?

Currently, it gives the option to export into gof format only.

Hi,

I have the requirement to dump large result sets into files. I am currently using %SQL.Statement and the result set created by it.

The DisplayFormatted is used to write a CSV. The query I used to test does not contain any filters, it is just a select * from a table with 16 million rows.
The file created is 2GB in size. The issue I have is that it takes 8 hours to create this file.

Hi folks!

Here is how I grant SQL access of user to a particular class/table:

GRANT SELECT, UPDATE ON Packacge_X.Table_Y TO UserZ

How can I grant SQL access of a certain user to a whole schema?

Hello,

I need to create a dialogbox  on my zenpage to confirm a Delete operation. 

I tried using below code on in a my client side method but its creating a blank dialog box.

zenLaunchPopupWindow('%ZEN.Dialog.confirmationDialog.cls','confirmationDialog','resizable,width=380,height=180');

Is there a way i can create a Dialog box with text "Do you want to delete" and two buttons "Yes" and "No" and store the response in the calling client/server method.

Thanks,

Hello Respected members,

I am new with InterSystems IRIS , want to setup the environment on RHEL 7.5 with multiple lun layouts (separate LVM for DB , Journal, and WIJ), 

I would like to get some help in setting up the same, as far as I know, the installation will go through on a single directory ( I did not see any option to chose path/directory for DB's or WIJ /journals), hence after installation I would like to move my DB's to separate LVM and WIJ on another LVM set

Please suggest or share the steps for the  same document if any for the same, that will be really helpful, Thanks

Regards

RS

Hi Community,

Please welcome the new video on InterSystems Developers YouTube:

⏯ Automating InterSystems IRIS Instances Configuration

We’ve published an update to the Serenji debug extension for Visual Studio Code, making it ready for the Workplace Trust feature in VS Code 1.57.

This allows the Serenji ObjectScript editor to work without restrictions across all workspaces and, by bringing it in line with the VS Code update, only allows the debugging feature to be used in trusted workspaces.

Hi all, I am new to IS Objectscript and I would appreciate some assistance regarding this. 

I am trying to find out how to count the number of elements within a dynamic abstract object and I am having some trouble using the size method.

Here is the code below:

The key value pairs are originally in JSON and I would have converted it in to an object for use.

We would need some help

We are trying to create a function to generate a random number with always 4 digits

We have already read the following topics:

https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cl…

https://community.intersystems.com/post/how-generate-random-string-fixe…

https://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KE…

How would you recommend to write a function to handle this use case?

Getting this error:

ERROR <Ens>ErrFTPPutFailed: FTP: Failed to Put file 'TestsDaily.xlsx.xlsx' 
(msg='Error in SFTP Put('\\Reporting\reports\Daily-Weekly\TestsDaily\To Be Processed\TestsDaily.xlsx','/TestsDaily.xlsx.xlsx') 
ERROR #7500: SSH Put Error '-2147024894': The system cannot find the file specified. [80070002]',code=0)

is this due to the file extension? Also, if its just because the file isn't there, how to fix that?

thanks

Some key points are emphasized in this article in order to save your time to get linux ldap client in cache working with windows AD (active directory) LDAP server. The first thing to do is to get successful TLS connection to windows AD. Raw tcp case is beyond of this article, there is no problem with it, it is trivial. Windows ldap server uses port 636 for tls and this port can be used to get ldap certificate. As we will see later there is reason for this. linux ldap client uses STARTTLS special ldap extension to switch plain tcp to TLS only. Hence, connection should use port 389. After
