Hi I am getting this message for some databases but not for others: This database is mounted as read-only due to 'Failed to access iris.lck file'! and not for others on Google Cloud community non-health edition.

For example this default database displays the message: Name IRISLIB Directory /usr/irissys/mgr/irislib/

But this default database does not: Name IRISSYS Directory /ISC/dur/mgr/

Hi Developers!

I'm pleased to announce that ObjectScript package publishing is now generally available on Open Exchange with this November 2019 release!

If you want your ObjectScript application to be published in ObjectScript Package Manager just enable "Publish in Package Manager" option:

And send the app on approving.

Once the application is approved it will be published automatically in ObjectScript Package Manager Registry and will be available for installation via ZPM client.

See the details below.

Hello!

I am taking the 'Creating an InterSystems Class Definition' course, and the Exercices asks to open a Terminal from the Management Portal to create and interact with a new object.

I have a case where I have an external table that lives out in MS SQL. Using Ensemble Security functions has anyone created a csp or cls page that acts like a portal to allow users to Update a multidimensional table without knowing SQL? I could clone the EnsPortal.LookupSettings but that was made for LUT which are only 2 columns.

I know its a long shot but trying to see if there was anything off the shelf that I can use to help meet the requirements of this project.

Performant index on date field

Is there a way to get a good performing index on a date field? I have tried various date property indexes and the query plan is always in a pretty high range. Below are query plan result values I have observed:

StartDate > '2019-12-01' --cost = 699168
StartDate = '2019-12-21' --cost 70666
StartDate between '2019-12-21' and '2019-21-28' --cost = 492058

The query plans above were for type %TimeStamp.

File System

Hello All,

I am working on Files where I have to compare contents of two files and display result.
e.g Suppose file1 contains data in Name and Roll form and file2 contains data in name and class form, so it should compare name from file1 and file2 and display those matching data(Name,Roll,class).

I have piece of idea about file system so any help would be appreciated.
Thanks in advance.

Regards,
Gunwant

Portlets that use data from DeepSee


In the previous part of this series, we saw how to reference a web page that will enhance our dashboard experience. Now we will look into referencing data that is already in our cubes.

In this example, we will be referencing the controller object and we will be extracting data from it. This data will then be displayed as text in our Dashboard. In Part 5, we will show how to incorporate this data into other charting libraries.

I am trying to use the %ListOfDataTypes functionality, but am hitting a limit of 50 characters for each entry, when being used in a Web Service. Is there a way to increase the number of characters that can be used in the %ListOfDataTypes through a web service?

Hi everyone,

I've encountered this annoying issue so many times before, if any one also encounter this issue, please share here if you have any solution.

So, I've been working on a web service project using HealthShare 2015. Sometimes I have to set a debug target to a csp file to debug it. If I pause the debug process about 3 minutes above or so (to examine an object, variable, etc..) the studio will hang.

Hi,

The class %JSON.Adaptor is very convenient,

I wonder if anyone faced the following scenario using it-

Exporting an object, that has a many to many relationship, and getting the details of the related objects.

For example, if we have three classes - Teachers, Students, and an intermediate class TeacherStudent .

The classes extend %JSON.Adaptor, and we would like to open a Student object, use %JSONExport, and get a JSON

That includes the details of the student and all the teachers that teach the student, something like:

Hi Developers!

Often we need to use relatively small arrays with constants, static arrays in algorithms, etc where we need to do something with each element of an array. There are several ways to deal with it in ObjectSctipt.

Previously I used to use globals, locals, PPG for this but not so long time ago figured out that %List is a way too handy.

Indeed, suppose we have an array of months and need to set up and use it in our code.
