InterSystems Caché database is a file where all the data, application scripts, and users, roles and security configurations are stored. Typically the name of the file is cache.dat.
Application to import 12 Datasets along with 43 tables dynamically by using LOAD DATA command which loads data from a source into an IRIS SQL table. List of Datasets
I'm happy to share with the community a web server log dataset from our longtime customer, an operating company.
Their webserver operates on Apache webserver and contains data which can be useful to analyse a load and search engines activity.
After installing the project, you will get the data for a few months that can show a typical load and activity of clients, robots and also you can see how it depends on day of week, holidays and time of a day.
A full cycle project, from initial data initialization, daily update products from the official website, a service for sending a course on request and receiving a schedule for any period.
For those of you who might be new to IRIS, and even those who have used Cache or IRIS for some time but want to explore beyond its usually-assumed boundaries and practices, you might want to dive into this detailed exploration of the database engine that is at its heart, and discover just what you can really do with it, going way beyond what InterSystems have done with it for you.
In this webinar, we’ll do a quick tour of the new LOAD DATA feature, also chime in on packaging global data or file data with ZPM, and run a data-generation script as part of a method in the zpm install.
As always, our experts will answer the questions on how to develop, build, and deploy datasets using InterSystems IRIS.
to dismount/mount a database, use Dismount() and Mount() methods in SYS.Database class available in %SYS namespace. NB: the database ID is its Directory
You'll find some examples of how to dismount/mount and check if a database is mounted (Mounted=1) or not (Mounted=0), and quickly see all the attributes of a database (via zwrite)
I've been accessing Cache tables from a developer/reporting side, but am now involved in a project to create a data warehouse for our application. I'm trying to find a query I can use to return the sizes of all the tables in the database, so we can identify the largest tables and handle those individually. Can someone give me a query I can run against our Cache database to return the sizes of all the tables from largest to smallest?
IRIS and Ensemble are designed to act as an ESB/EAI. This mean they are build to process lots of small messages.
But some times, in real life we have to use them as ETL. The down side is not that they can't do so, but it can take a long time to process millions of row at once.
To improve performance, I have created a new SQLOutboundAdaptor who only works with JDBC.
BatchSqlOutboundAdapter
Extend EnsLib.SQL.OutboundAdapter to add batch batch and fetch support on JDBC connection.
In my previous articles I demonstrated the steps to connect and retrieve data from Caché from Appeon PowerBuilder by using ODBC. In this article I will demonstrated how to Save data to Caché with Appeon PowerBuilder (https://www.appeon.com/products/powerbuilder) by using ODBC
I am relatively new to Intersystems cache database management. As I understand it, a database is set with a maximum size or unlimited and the size of each space allocation for the database is defined. My understanding is that the cache database will then manage the allotment of space to the database as the current space allocation is consumed. Though I do not know why one would want to do this, I have been told that the space allocation to a database can be set to be handled manually. This is something, if true, I was not aware of.
I have a workstation with a CACHE instance up and running.
On that same workstation there is also an instance of IRIS (fresh install). I would like to migrate manually the CACHE database to IRIS (ideally, all globals, routines and classes).
What I tried is to copy C:\InterSystems\Cache\mgr\CACHE.DAT to C:\InterSystems\IRIS\mgr\IRIS.DAT (after shutting down both instances) but it does not work.
I got the following message :(112) The service for the IRIS instance did not start.
In this webinar, you'll get an overview of the interoperability capabilities of InterSystems IRIS, and we'll show you how to use the PEX. Also, we’ll discuss and answer your questions on how to build interoperability solutions using InterSystems IRIS and IRIS for Health.
I would like to know if an encrypted caché database can run significantly slower than a normal "unencrypted" database, in a way that is noticeable to the end user (e.g. slower response time for most pages, especially the ones that rely on read/writing to globals).
I searched in Intersystems knowledge base and couldn't find anything related. I'm looking for possible before/after benchmarks.
This data set is my personal log of running reviews in Open Exchange. It is just a table with 504 records and no special features. Ready to run experiments on various ways of indexing.
Appeon PowerBuilder is an enterprise development tool that allows you to build data-driven business applications and components. It is one of a suite of Appeon products that together provide the tools to develop client/server, Web, mobile, and distributed applications.
I hope you can help me because this is a very serious that I can't wait to resolve... Our back-up is currently taking 3 up to 4 Gb per day and we don't know why. We had 270 Gb yesterday and we are today at 274.3 Gb. We keep a computer history of the messages for only 50 days. Here is a picture of what's currently taking the most data place in our healtshare system:
(don't forget that our DB is also connected to the back-up, maybe it is related, I don't know)
Upon creating namespace I selected same database for both Globals and Routines. How can I separate both the databases. Please note that I already have data and code saved in database.
The index we want to use is called "iFilter". Currently we use the following technique of ignoring all other indices because the automatically chosen index is always too slow.
