In a single server environment, it is rather easy to create a transaction consistent backup.

Simplified:
You find (or force a specific point in time with no open transactions.
Freeze your server, take a snapshot and you are done.

Hi, DeepSee experts!

I need to call a listing programmatically other than the default.

I can do that with %LISTING keyword. E.g. in Samples:

Hi,

I am placing Cache instance in backup mode by using the command:

csession <INST> -U%SYS "##Class(Backup.General).ExternalFreeze()"

and I see in the console log a message similar to follows:

"Journaling switched to: /cache/mgr/journal/20170330.002"

Now, is there a way to programmatically find out this journal file name? In fact, I am interested to find out the journal file that is switched. For example, in the above case, that would be "20170330.001".

Thanks,

Raghu

Hi,

An exception occurs randomly.
I expect the value of ^TEST to be 20, but it's not.
Did i miss something like closing, flush the stream or locking the global?

Exception

Hey community! How are you doing?

I hope to find everyone well, and a happy 2022 to all of you!

Over the years, I've been working on a lot of different projects, and I've been able to find a lot of interesting data.

But, most of the time, the dataset that I used to work with was the customer data. When I started to join the contest in the past couple of years, I began to look for specific web datasets.

I've curated a few data by myself, but I was thinking, "This dataset is enough to help others?"

I am surprised with the performance (poor) of Native API for .NET

Following code (where ^testGlobal,node1 has 50 records) takes 5 seconds to run. Anyone else think there is room for the improvement?

The pandemic that struck the world in 2020 made everyone follow the news and the numbers that involve the COVID-19.

Why don’t you take that opportunity to create something simple and pleasant, to follow the number of vaccinations worldwide?

To face this challenge, I'm using the data provided by Our World in Data - Research and data to make progress against the world’s largest problems.

They have a dedicated repository on Github with the data of COVID-19, and I took the vaccination data to help me with my tracker.

Hi,

Can anyone please recommend an editor for cache database. I am looking for free version.

I am using winsql free version but data is missing while extracting or copying data from winsql.

Thanks

Let's take a closer look at the DC Wall of Fame 2018 and greet everyone with big applause!

I have a query that I am attempting to run, but inner query is being rolled up into the overall query - per the optimizer (and jobexam observation). While I know that if the inner query runs first, I will eliminate a number of records (making the result set smaller, and return quicker).

Just an example of what I am attempting to do:

What is COS Expression? Is the related to SQL Expression?

Can you give a basic code or query related samples? If anyone give a sample, it's understanding easily.

One of the great features in InterSystems IRIS is Monitoring InterSystems IRIS using REST API. This enables every InterSystems HealthShare instance with the ability to use a REST interface to provide statistics about the InterSystems HealthShare instance. This feature includes information about the In

I've written a stored procedure for SQL as follows. The second parameter is a search path that may use a single quote or bracket as part of its expression.

When the expression uses a single quote, I can double it within SQL, and it works well. In this example, 'testDate' is written as ' ' testDate ' ' .

Select HISOL_MEAS.SQLProc_JSONpath(fullAnnotation,'HbA1cTests.sort(''testDate'',false).resultValue') As reverseSortedTests

In the next example I'd like to use brackets (see below), which causes an error.

Hi folks

We are upgrading TrakCare from 2017 version to 2020, when I tried to reconnect our applications with new upgraded environment through IRIS ODBC driver instead of cahe ODBC driver I got this error: "the driver doesn't support the version of ODBC behavior that the application requested" while it is working fine with cache driver. Any help please ?
