Trying to use the $SYSTEM.SQL.DDLImport to import XML File that has ClassMethods, no SQL Table, but it doesn't appear to be working. I can use this ClassMethod to create SQL Tables. The manual method I have been using is to go into Cache Management Portal, Classes, Import.
I create an XML file first, then run the following to import but get no errors. Any ideas?
Someone know which impact would have my database changing the locale and its collationTable? I understand it should works fine, without any drawback.
Could someone else confirm my assumption or tell me what could happen? Has anyone changed something like that? (Not to russian, japanese, chinese, etc..)
Hello everyone, First sorry for the ignorance, but, as I am new in the InterSystem world, I came to the following doubt: Thinking about a database migration.Is it possible, in a non-traumatic way, to take an Oracle database and migrate it completely to Caché?
I have a Problem with the Session Handling in .csp.
I wrote all my Web Services in .csp-Pages and do the work for example in the OnPreHttp Method for to get some data.
After that the Web Service response is in JSON.
I call These Web Services via fetch in my react Single Page application, also Many request parallel. The react App is Rolled out as index.html. Everything Works Fine with the session Handling via Cookie.
I have noticed a problem in some new code I did on one of our productions. I think it is leading to 2 problems.
I have a file, lets call it 1111111111_2300.pdf.
We make the file UNIQUE to avoid an issue. This filename in the working directory gets a session ID Added to it before the .pdf. So lets say it was session ID 9 it would be 1111111111_2300#SID9.pdf in a working directory .
There are further operations to be done on this document before it is sent. For various errors an email is sent back to service users.
I have already asked a question about migrating an Oracle database to Caché, and I was promptly answered.Now, I have one more question, however it is more conceptual.In general, any tool defends its benefits, and looking at Caché's, among many, there is a lot of talk about speed.The question is, if I already have a database, and at the moment, its performance is not a problem, I would like to know what else could influence the change of this database?Remembering that it is functional and without any apparent problem.
I am new to InterSystems Cache and want to explore the database features for one of the use cases we have.
I am trying to find the community version of it from in https://download.InterSystems.com but only found InterSystems IRIS and Intersystems IRIS health community versions.
I have this question for a long time. When I make an insert by SQL from an external application in the fields of type %String, if they are empty, it writes the character $c(0) in the global.
Is there a way so that if an Insert is received in a field of type% String with null value instead of the $ c (0) it leaves it empty?:

Hi Cache team, I am in the need of listing all the user defined schemas that are present my Cache db and also the user defined tables and views and Columns of those tables and views through Queries. So that I can write some JDBC code to run the queries and fetch the above metadata. Any help is appreciated.
I'm looking for the best strategy for extracting data from a Cache table that houses 86 Million lines of data and around 190 columns. I'm currently using DBeaver and the Invoice Service dates go back to 1996. Optimistically I'm looking to pull to a pipe delimited flat file, but even a year's worth of data takes many hours to get query results.
Class Queries in InterSystems IRIS (and Cache, Ensemble, HealthShare) is a useful tool that separates SQL queries from Object Script code. Basically, it works like this: suppose that you want to use the same SQL query with different arguments in several different places.In this case you can avoid code duplication by declaring the query body as a class query and then calling this query by name. This approach is also convenient for custom queries, in which the task of obtaining the next row is defined by a developer. Sounds interesting? Then read on!
Can you please guide me on how to restore the .cbk file from the 2015 Cache version into the 2017 version or any other versions of Cache or IRIS software? I have a new instance on my server. It's an entirely new server. I have a .cbk backup file. I want to restore the backup file into a new namespace which one I will create on my new server. When I am trying on ^DBREST utility, I am getting "This is not a Cache Backup File" this error.
$LIST string format and %DynamicArray and %DynamicObject classes
IRIS, and previously Cache, contain several different ways to create a sequence containing a mixture of data values. A data sequence that has been available for many years is the $LIST string. Another more recent data sequence is the %DynamicArray class, which along with the %DynamicObject class, is part of the IRIS support for JSON string representation. These two sequences involve very different tradeoffs.
Presenter: Anton Umnikov Task: Identify your slowest SQL queries and tune them for better performance Approach: Use InterSystems’ query profiling and analysis tools. Discuss how system configuration can affect performance
This session will show you how you identify the weakest link in your application SQL and introduce you to the fine art of tuning those queries. To do this we will take a look at InterSystems query profiling and analysis tools, as well as how system configuration can impact SQL performance.
Problem: Obscurity on how our SQL engine works

Good day!
Is there an opportunity to debug the ISCAgent behaviour (in Linux)? ISCAgent uses /etc/iscagent/iscagent.conf as configuration file, but in docs I've found a description only for two parameters (port number and interface - http://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY=...). Other parameters I can see by running /usr/local/etc/cachesys/ISCAgentCtrl status:
