Hello everyone.

I'm new to Caché.

I would like to know how I can connect my PHP application to the intersystems database.

Is it the same as MySQL?

Need help.

Thank you

What is Journaling?

Journaling is a critical IRIS feature and a part of what makes IRIS a reliable database. While journaling is fundamental to IRIS, there are nuances, so I wrote this article to summarize (more briefly than our documentation which has all the details) what you need to know. I realize the irony of saying the 27 minute read is brief.

Is there any way (on a Window machine) to rename an installed instance? I installed my instance as 20201 and now I've upgraded in place to 2020.4 and I would like to change the instance name to be 20204, but I'm not sure how/where/or-even-if-possible to rename the instance.

Am I out of luck, or is this possible?

Thanks

Hi All, I need a documentation to configure csp in iis version 7, Any one have documentation regards?

The Documentation team in InterSystems Learning Services is happy to announce the new InterSystems IRIS Server Migration Guide!

Have you ever wanted to copy, move, or clone an instance of InterSystems IRIS to a new server? Maybe the operating system on the old server is no longer supported, or maybe you want to add a new member to an existing mirror. Migrating your application databases is easy, but what about your tasks, users, roles, resources, and other security settings? What do you need to migrate, and how best to do it?

Hi, all!
As I know, InterSystems recommends the use of Huge Pages. And if count of Huge Pages is enough, we'll see (in cconsole.log) something like this during Cache startup:

But if count of Huge Pages is not enough for location of all Globals and Routines caches, Cache won't use Huge Pages.

Currently, we have an application running in one namespace ("Database B") that has globals and routines mapped to another database ("Database A"). After enforcing clean up on Database A, we found that 90% of the disk is free. We would like to compact Database A and release the unused space. However, we are running OpenVMS, which seems to be the issue.

For databases consisting of only globals, we are able to use ^GBLOCKCOPY; however, we need to ensure that the routines and mappings are also copied.

No reason apparently,

no details on audits, no traffic for that, no process to justify this, some ideas ?

In System Management Portal, I'm on UnknownUser (which I've accidentally removed the %All role from), so I log out of UnknownUser and try to log in as root or Admin, but only see the following screen:

So i'm having this problem with the task manager, the tasks simply stopped running. I had a problem with queued massages and trying to figure out what to do i'm afraid I may messed up something else, can someone help me ?

When you first start working with InterSystems IRIS, it’s a common practice to install a system with only a minimum level of security. You have to enter passwords fewer times and this makes it easier to work with development services and web applications when you're first getting acquainted. And, sometimes, minimal security is more convenient for deploying a developed project or solution.
And yet there comes a moment when you need to move your project out of development, into an Internet environment that’s very likely hostile, and it needs to be tested with the maximum security settings (that is, completely locked down) before being deployed to production. And that’s what we’ll discuss in this article.
For more complete coverage of DBMS security issues in InterSystems Caché, Ensemble, and IRIS, you may want to read my other article, Recommendations on installing the InterSystems Caché DBMS for a production environment.
The security system in InterSystems IRIS is based on the concept of applying different security settings for different categories: users, roles, services, resources, privileges, and applications.

Users can be assigned roles. Users and roles can have privileges on resources — databases, services, and applications — with varying read, write, and use rights. Users and roles can also have SQL privileges on the SQL tables located in databases.

I was wondering if there was a certain procedure or documentation on securing (Https://) the Web Portal into IRIS/Ensemble?

Currently we are using LDAP Delegated Authentication to access the Web Portal using LDAP. However as more and more emphasis is put on securing applications within networks, I can see Management/Security asking us to make sure that the web portal is more secure.

Hello,

I have a problem with an Ensemble instance on Windows to access to a network shared directory. Ensemble service (services.msc) is executed with a user which has access to this network shared directory :

- When I try to copy or access files from a terminal ==> this is OK : the command w ##class(%SYS.ProcessQuery).%OpenId($Job).OSUserName returns the user defined in Ensemble service logon screen.
