Git plugin for Cache Studio

Has anyone recently deployed the cache-git-studio plugin from Github repo?

In particular, I see that this plugin is installed at the namespace level, so it appears for each user have their commits in their own name, they must all be running a locally installed cache server when doing their dev work. I suspect that is the preferred way.

In my organization they are currently just accessing a remote cache server from Studio. In that scenario, it looks like it would be one installation of git for the whole team. and thus only one shared git user.

Hi community,

I need to write an SQL query to fetch a random record from a table, that table has millions of data.

In postgresql, for example, there is a RANDOM() function to do something like that:

SELECT column FROM table
ORDER BY RANDOM()
LIMIT 1

Is it possible to do something like that in Caché?

Thanks in advance

What’s the contest about?

In the last year, InterSystems added and expanded Native APIs for Java, .NET, Python, and Node.js. The Native API provides high speed access to globals, the ability to instantiate and use ObjectScript objects, and fine-grained control over transactions.

I have been using %Net.FtpSession and while it works, its handling of file/directory listings from an FTP server is less than ideal and, while this is due to the FTP protocol itself, the class could be written to handle this as would an FTP client such as FileZilla and command line/class FTP handlers for other languages. I was wondering if anyone knows how the Ensemble adaptor works with this in case it provides code that would help, though the source does not seem to be available. Below are the issues I see in FTP, some are based on past experience writing our own FTP handler in the past

InterSystems has corrected two defects that affect online backup of very large databases. Backups taken via external methods, such as snapshots or direct file copies, are not affected. These defects exist in all released versions of all InterSystems products.

Hello Community,

I want to secure a SOAP Webservice (an EnsLib.SOAP.Service one, if that matters) adding a SSL/Username Policy to it. As im not sure how detailed my request here should get, ill try giving a detailed as-is description of my setup, what I've tried, how I tried to test the connection and what problems including some logs I ran into.

As a small foreword: I'm pretty new to the whole security aspect of intersystems and soap itself.

Hello,

We are trying to connect to a database through a JavaGateway.

We observe that the JavaGateway reports:

Failed to start the Java Gateway server: ERROR #5002: Error de cache: <UNDEFINED>zGetJavaVersion+22^%Net.Remote.Service.1 *versionWithPrefix

We have checked that we do have the Java Home set:

/usr/java/jdk1.8.0_65

And we have seen the java files in the server:

Hello all, I have a question about constucting thousands of clones, and scope.

In my code, I'm looping through a database, say 200k+ objects, and creating a clone of each object (we need to evaluate a modified clone of the object, but not account for what's on disk).

I see this a lot in the documentation:

Debugging in HealthShare

Hi, if you develop production with HealthShare, you may have noticed there is a nice tracing feature available - HS.Util.Trace.Operations. This feature allows visually tracing debug information, in structured way. It complements good old logging macros like $$$LOGINFO, $$$TRACE and alike.

I use this feature a lot. However, it has limited functionality, it works nice with classes that extend XML Adapter, streams or data types, but it doesn't work well with arbitrary objects that do no extend from XML Adapter.

IRS Docker micro Durability

Allow limited durability for demo and development IRIS-Docker-micro-Durability During development of a container based demo I found the need to access a fresh docker
an instance of IRIS image (e.g intersystems/iris-community:2020.2.0.199.0) over and over.
To bypass loading my code repeatedly I developed this workaround.

It is a reduced variant of Docker - light weight durability
