We are migrating to new servers, and I need to copy the information from Business Partner's over to the new server. Is this information in a Global or SQL table somewhere that I can export and import into the new IRIS environment?

Thanks

I am looking into creating a ZSTOP as you probably have seen from my previous posts, is there a way to capture the type of shutdown that occurred? So say if there was an unknown hardware failure (forced), vs a user shutdown? Mainly looking for user or system shutdown when we force another destination to become the primary in the mirror. So if a user shutdown the production to do.,... Task A, Task B etc..

Thanks

To prepare a migration to IRIS I use Docker images.
The (aged) application is built around Caché Terminal
And on Windows,  IRIS uses the same ctelnetd.exe as Caché.

In my Docker installation, Telnet Settings are just grayed out in SMP.
and my Terminal can't 'connect.
Port mapping is OK and verified with TCP

Working from the console in Docker  with the whole set of ESC and
screen formatting is not acceptable.
We tried WebTerminal but there is just no Partition behind as in Terminal.

How can I switch on Telnet support in the Docker image?
 

Released with no formal announcement in IRIS preview release 2019.4 is the /api/monitor service exposing IRIS metrics in Prometheus format. Big news for anyone wanting to use IRIS metrics as part of their monitoring and alerting solution. The API is a component of the new IRIS System Alerting and Monitoring (SAM) solution that will be released in an upcoming version of IRIS.

However, you do not have to wait for SAM to start planning and trialling this API to monitor your IRIS instances.

I am working on setting up our Failover techniques as we move to a Mirror Environment with a Arbiter, 2 Failover Nodes, and a Async (DR) Node. There are some system commands that I would like to call when the Mirror moves, and I am working on a ZMIRROR routine for that, but I also wanted to create an additional step if we wanted to manually shutdown and for the Mirror to move. So I was looking at using ZSTOP to call a couple of different items while shutting down, while the documentation has an example a couple of questions come to mind about using ZSTOP.

I am new to setting up a mirror environment....

We will have a Arbiter, Two Failover members (A,B), and a Async (DR) member (C). I have the two failover members in sync and are configured for Arbiter Control.

My question is about the Async member, when I initially set it up I pointed it to the mirror on the primary node A.

Is that correct?

What happens to the Async member (C) if we fail over the mirror to the secondary member B?

We are trying to script a High Availability Shutdown/Start script in case we need to fail over to one of our other servers we can be back up within mins. Is there a way to configure the startup procedure to Automatically Stop/Start the JDBC server when shutting down or starting up cache? is there an auto setting we can change?

Thanks

Can someone confirm that HealthShare Health Connect 2022.2 is the correct latest release that is available via the Online Distribution? I tried looking at the HealthShare Health Connect on WRC and now do not see a 2022.2 or 2022.3 version. Is this correct? So I shouldn't be running 2022.2? Did Health Connect get renamed? A couple of months ago I downloaded HealthConnect-2022.2.0.368.0-lnxrh8x64 but not seeing it now on the WRC site.

Hi Team , 

Can I please check if anyone has encountered SOAP authentication error when trying to submit a certificate signing request or when trying to get certificate .

I configured a local CA server without SMTP configuration and I configured a local CA client. These steps worked okay.

Then I tried to Submit Certificate Signing Request to Certificate Authority server and I am getting the following error :

Similar error is appearing when I try to use the Get Certificate(s) from Certificate Authority server option

I am trying to adjust my VSCode settings.json to make my repository to Server Side Source Control. When Adding "uri" to the settings.json to change the setting but VSCode is telling me that the Property uri is not allowed.

Why is this happening?

Some Usage cases

1. A deployment may consist of two high availability instances and two disaster recovery instances in a different data center.

The corresponding UAT environment could replicate this giving a total of 8 instances. How do you confirm CPF and Scheduled task alignment across ALL instances.

2. Another team (possibly in anther organization) makes changes to an IRIS instance to correct a problem, improve security, or modify shared system task configuration. Capture the CPF before and after to see what was done across instances.

Introduction

There are many entities in IRIS which are extremely difficult to transfer to another system.They usually contain important system-stored objects: users, roles, privileges, mappings, and applications. The exception to this list is for resources, which are facilitated by the ability to select and save them from the management portal interface [System > Security Management > Resources] Yet, things are not as good with other system objects.

Quality of Service Mirroring Timeout Configuration

           The Quality of Service (QoS) timeout determines how long a Mirror configuration of Caché will tolerate a loss of connectivity between its members. However, the exact method by which it does this and what that means for someone looking to configure this setting on their own system is not entirely obvious.

Hi All,

I want to move into CACHE/IRIS DBA role. Can anyone suggest what all learning must be done in order to move in this role. 

It would be great if you can provide the learning path as well for the topics. (links from I can learn the provided topics)

Thanks in advance!!

I am trying to migrate our SQL Connections from HealthShare Health Connect 2018.1.3 to IRIS HealthShare Health Connect 2022.2 using the Data Export/Import Wizard through the Management Portal. I am able to export the data fine, but I am running into issues trying to Import it into 2022.2 using the Data Import Wizard. When I run through the steps it is not importing everything from the txt file I created from 2018.1.3. I would rather not have to rekey all the connections if possible.

Here is the Background Task Error Log

Is there a way around this Validation error?

Overview

Predictable storage IO performance with low latency is vital to provide scalability and reliability for your applications. This set of benchmarks is to inform users of IRIS considering deploying applications in AWS about EBS gp3 volume performance.

Summary

• An LVM stripe can increase IOPS and throughput beyond single EBS volume performance limits.
• An LVM stripe lowers read latency.

How do I delete these system tasks that are obsolete..  The task in the attached image has no possibility to delete... 

We have a UNIX VM with an InterSystems IRIS instance which we cloned for testing purposes, and we have found that $System (which is used for self-identification in email notifications) is still showing the hostname of the original VM, rather than the hostname of the cloned VM.  This is coming from $System.INetInfo.LocalHostHame().

Does anyone know what you need to change on a UNIX clone in order for it to display the appropriate new host name in $System?  

In our current UCR arhcitecture, we use two installations. We have one machine with Access, Registry and Edges and one machine with the ODS. On the machine with the Registry, I can create a user/clinician. When I log into the management portal with this user, a so-called delegated user is created in the cached users table. So far everything is going well. 

When I try the same on the machine with the ODS I get the message : 'ERROR #822: Access Denied' . so no delegated user is created.... Does anyone have any idea where I can find the solution?

Introduction

Memory is managed in pages.  The default page size is 4KB on Linux systems.  Red Hat Enterprise Linux 6, SUSE Linux Enterprise Server 11, and Oracle Linux 6 introduced a method to provide an increased page size in 2MB or 1GB sizes depending on system configuration know as HugePages.

At first HugePages required to be assigned at boot time, and if not managed or calculated appropriately could result in wasted resources.  As a result various Linux distributions introduced Transparent HugePages with the 2.6.38 kernel as enabled by default.  This was meant as a means to automate creating, managing, and using HugePages.  Prior kernel versions may have this feature as well however may not be marked as [always] and potentially set to [madvise].  

Transparent Huge Pages (THP) is a Linux memory management system that reduces the overhead of Translation Lookaside Buffer (TLB) lookups on machines with large amounts of memory by using larger memory pages.  However in current Linux releases THP can only map individual process heap and stack space.

Hi everyone,

I have an issue when calling Trakcare's webservices using a web application.

The issue is that, the browser is blocking the queries because of the CORS Policy.

In fact, the browser is sending a first HTTP query OPTIONS called "preflight" (in Chrome's developers tools) and Apache server answers with no CORS Control Origin in Header (CORS header ‘Access-Control-Allow-Origin’ missing). So the query is blocked and does not reach the Webservices server (IRIS Interoperability).

I know there is the ability to enable Rule Sets within a Business Rule by dates, but what about Sub-Rules or just Rules in general? We have an upcoming go-live that is at Midnight and I was wondering if there was a way I could script out enabling rules/sub-rules within a Business Rule to save my team some time and headaches. Or is the best practice is just to create another rule for the go-live, then move it over once we are live...

YASPE is the successor to YAPE (Yet Another pButtons Extractor). YASPE has been written from the ground up with many internal changes to allow easier maintenance and enhancements.

YASPE functions:

• Parse and chart InterSystems Caché pButtons and InterSystems IRIS SystemPerformance files for quick performance analysis of Operating System and IRIS metrics.
• Allow a deeper dive by creating ad-hoc charts and by creating charts combining the Operating System and IRIS metrics with the "Pretty Performance" option.
• The "System Overview" option saves you from searching your SystemPerformance files for system details or common configuration options.

YASPE is written in Python and is available on GitHub as source code or for Docker containers at:

I am trying to troubleshoot an issue I am having with the JDBC Gateway Server crashing at the %SYS level. I have numerous Linked Tables that are using JDBC to connect to a MS SQL database/tables to query values. I have written queries in other class files and within the class definition of the linked table to do the queries.

1. Should I be running the query in the class definition of the linked table as a class method? or is it best practice to run the query as a class method outside of the class definition of the linked table?

2. I was reading documentation and came across the Config.

NB. Please be advised that PKI is not intended to produce certificates for secure production systems. You should make alternate arrangements to create certificates for your productions.
NB. PKI is deprecated as of IRIS 2024.1: documentation and announcement.

In this post, I am going to detail how to set up a mirror using SSL, including generating the certificates and keys via the Public Key Infrastructure built in to InterSystems IRIS Data Platform. I did a similar post in the past for Caché, so feel free to check that out here if you are not running InterSystems IRIS. Much like the original, the goal of this is to take you from new installations to a working mirror with SSL, including a primary, backup, and DR async member, along with a mirrored database. I will not go into security recommendations or restricting access to the files. This is meant to just simply get a mirror up and running. Example screenshots are taken on a 2018.1.1 version of IRIS, so yours may look slightly different.

Hi:

Are these all depreciated in 2022.1? Our tasks don't run as can't find it and using a search of the docs they are last recorded against 2021.1?

Search InterSystems Documentation
There isn't any line in release notes to note that these no longer exist. 

Trying to identify which records in the %SYS.Audit table are fails.

Eg, as user "WORKER", I run an attempted a grant, the terminal returns:

[SQLCODE: <-112>:<Access violation>]
[Location: <ServerLoop>]
[%msg: <User WORKER does not have required privileges to grant the privilege(s)>]
[ISQL]ERROR: Could not SQLExecute
 

but the record in the audit table gives
